Publications related to the Manchester Museum’s Entomology Department, an 2021-22 update

A selection of the papers published in the last 2021-22 academic year, based on or containing references to specimens or collectors associated with Manchester Museum’s Entomology Department

This blogpost is the latest of the annual series summarizing publications based on Manchester Museum’s Entomology Collection over the last academic year. A total of 32 paper were published in the period between 1 August 2021 to 31 July 2022 referring to the specimens from our collection. Topics included the analysis of historical data, the support of conservation programs or ecological studies, and the legacy of collectors (including former Keeper of Entomology, Colin Johnson; Figure 1a). Descriptions of new species and accounts of particular MM’s arthropod collections are also presented. The publications were authored by more than 50 researchers from 12 countries (Belgium, France, Italy, Spain, Finland, Israel, Russia, Ukraine, India, Japan, South Africa and the UK), their list is given below.

The majority of the papers were devoted to descriptions of new species: viz., spiders from Spain, Portugal, Italy, UK, Russia, Ukraine, India, Nepal and Kenya; beetles from Côte d’Ivoire, Sierra Leone, Zambia, China and Taiwan; and stick insects from Vietnam (Figure 1a). Over two thirds of the papers focused on spiders (Araneae), with the remaining third dealing with five other arthropod groups (Figure 1b).

The value of sharing data from specimens

The MM’s Entomology Department was one of many natural history museums and societies supporting conservation initiatives. By gathering and using historical data from specimens and records of the Chequered skipper butterfly Carterocephalus palaemon (Pallas, 1771), Wildman et al. obtained a better understanding of how this species declined to extinction in England in 1976 and used this information to recommend conservation activities for other declining or endangered species. Records of this species, including those from the Manchester Museum, are now part of the Butterflies for the New Millennium (BNM) database created by Butterfly Conservation and the Biological Records Centre (BRC) (Wildman et al. 2022).

The updated checklist of four families of the order Diptera (Atelestidae, Brachystomidae, Empididae and Hybotidae) for Lancashire and Cheshire is not just a species list. Compiled by Phil Brighton using museum specimens and other sources, including local and national recording schemes, the paper includes relevant information on distribution, ecology, habitats requirements, and national and local conservation status. Data from the records and specimens assembled by former Museum’s Keepers, Harry Britten (from 1920 and 1950) and Alan Brindle (1950s), made a major contribution to this checklist (Brighton 2021).

News from the Entomology Department

Colin Johnson, the last person to hold the title Keeper of Entomology at the Manchester Museum (1982 – 2003) sadly passed away last year. Colin was an internationally renowned expert on beetles who described an amazing number of species new to science (especially tiny beetles of the family Ptiliidae, Cryptophagidae and Latriididae; for more information see in the blogpost “A life devoted to describing tiny beetles”). Colin contributed greatly to the expansion of the British Coleoptera at MM (92% of known British beetles are represented in the collection). An account on Colin’s work and legacy was compiled and published by his friend, Roger Dennis, in the obituary published by the Entomologist’s Monthly Magazine (Dennis 2022; Figure 2).

J. C. Otero & J. M. Pereira described Atomaria (Atomaria) johnsoni, a new species of the family Cryptophagidae from China, dedicated to Colin Johnson (Otero & Pereira 2022), making a total of 19 species named after him.

Accounts of the Museum’s collections

• A paper on the collections of mites and ticks (Acari) in the Manchester Museum, written by two of our honorary curators (Graham Proudlove and Laurence Cook) and the Curator of Arthropods (Dmitri Logunov), gives a brief account of the history of the collections and collectors (including the work of former Museum keepers and assistants). It is also includes an analysis of historical specimens and material acquired in the last decade, for the first time. This collection of 2900 slides preparations was recently recurated, documented and stored in the original standard Hill units and drawers (Proudlove et al. 2022; Figure 3a&b). This paper immediately started generating numerous enquires regarding this collection, which was never published before.

• A publication regarding a small butterfly collection from Sierra Leone, given by Lieutenant Leech in 1895, explores not only the social life of the century and the colonial past, but also shares information on the natural heritage of west Africa. This collection had not previously been documented, apart from the handwritten labels. It contains 93 identified species of butterflies, moths and insects of various orders as well as other material. The specimens were collected between 1891 and 1893 in the vicinity of Freetown, the capital of Sierra Leone, however there are uncertainties about collection localities for a group of specimens. Many butterflies were kept in triangular paper envelops (Figure 4a). The specimens have been mounted, labelled, identified and accessioned (Cook et al. 2022; Figure 4a&b).

• In June 2022, a Special Issue (Vol 19) of Arachnology, edited by Dmitri Logunov, published 24 papers and proceedings from a symposium celebrating the life and legacy of John and Frances Murphy and Mike Roberts. Members of the British Arachnological Society (BAS), speakers from 39 countries and many spider enthusiasts, attended the online event. All symposium talks are available via the BAS YouTube channel. This volume contains eight papers based on the symposium presentations and 16 other contributions (freely available here).

Within the Special Issue, the scientific legacy of Murphy’s publications and archival material was analysed and summarised by Logunov (Logunov 2022a). This paper also includes a brief account of Frances and John’s life, fieldwork (Figure 5) and a brief description of the spider collection assembled over 45 years (Logunov 2022a; Arzuza Buelvas 2018). The Murphy Spider Collection and their archival materials are available at the Manchester Museum.

The issue also contained seven more taxonomy papers based on specimens of the Murphy spider collection (Azarkina 2022; Ballarin & Pantini 2022; Sherwood et al. 2022; Logunov 2022d; Pett 2022; Tanasevitch 2022; Zonstein & Marusik 2022). New species and a new genus from Kenya, and new species from Italy were described (Azarkina 2022; Ballarin & Pantini 2022; Pett 2022; Zonstein & Marusik 2022). The issue also contained an annotated catalogue of tarantulas (family Theraphosidae) retained at the Manchester Museum (Sherwood et al. 2022; Figure 6).

Highlights of other papers and authors

• Laurence Cook and Chris Shortall analysed the frequencies of melanic forms of three moths over the last century, including the melanic morph, carbonaria, of the Peppered Moth Biston betularia, using data of the Rothamsted Insect Survey. This industrial melanic morph was not present in the analysed data. However, the intermedia morph (Biston betularia insularia) and the industrial melanic forms of the Scalloped Hazel (Odontoptera bidentata) and the Pale Brindled Beauty (Apocheima pilosaria) were found widely over Britain. Possible reasons to this finding are discussed in the paper (Cook & Shortall, 2022).

• Specimens of stick insects, genus Trachythorax, were used in a review of this taxonomic group. This project examined specimens from related taxa including type materials, records of images and data collected during citizen science initiatives and described stick insects new to science from Vietnam (Bresseell, J. & Constant, J. 2021; Figure 7).

Looking or behaving like a tiger – meet the ‘tiger insects’ from our Collection

In the traditional Chinese calendar, 2022 is the Year of the Tiger. In Chinese culture, tiger is the king of all beasts, symbolizing power, majesty and beauty. Let us to celebrate the beginning of the Chinese New Year 2022 with a selection of ‘tiger insects’ from the Manchester Museum’s Entomology Collection. In this blogpost, a few examples of tiger-like colour patterns in moths and butterflies and tiger-like predatory behaviour in some amazing beetles are presented.

Warning colouration

A tiger’s bold pattern of bright orange body coloration with dark stripes makes them less visible to their prey (it is the so-called disruptive colouration). On the other hand, the conspicuous dark and orange colouration of some moths and butterflies is a clear warning signal to predators. This is the case of the adults of the Garden tiger moth or Great tiger moth Arctia caja. When threatened, this moth can release neurotoxin, making it inedible.

The Garden tiger moth was one of the favourite moths for early collectors who were interested in creating unusual coloration patterns. This species is now protected in the UK; its population has declined by 89% over the past 30 years.

The Harmonia tiger-wing or Harmonia tiger Tithorea harmonia shows the pattern of a toxic butterfly. This species is one of the common and most widespread of the toxic ‘tiger-like’ species that can be found from Mexico to South America. Its larvae feed on Prestonia acutifolia (Apocynaceae), a plant with toxins, and pass the poisons to adults. When eaten by predators, this butterfly leaves an unpleasant taste.

The Tiger butterfly or Striped Tiger Danaus genutia is a very common species throughout India, Sri Lanka, Myanmar, South-East Asia, and Australia (except New Guinea). It has the same appearance as the famous Monarch butterfly Danaus plexippus of the Americas. When the wings are open, both female and male show an orange or yellow-brownish coloration with black venation. Its larvae obtain toxins from plants, which also leave an unpleasant smell and taste to their predators when the adult is eaten.

Aggressive predators and fast runners

Tiger beetles are known for their running speed and their aggressive predatory habits, just like true tigers. It is a large group of some 2600 (sub)species of the subfamily Cincidelinae. Their characteristics include large eyes, long legs adapted for sprinting, and a striking pair of curved and toothed mandibles (=jaws) for catching prey (see video here). The Tiger beetle species Rivacindela hudsoni from Australian deserts is considered the fastest insect in the world, with a running speed of 9 km/hr (120 beetle body lengths per second). More about Tiger beetle adaptations and characteristics here and here.

Tiger beetles lay their eggs in the sand. After hatching, the larvae dig a tunnel and wait in ambush in the tunnel’s mouth for any small invertebrates passing by. The larvae strike and catch their prey with powerful jaws (see video here). Such voracious larvae are known in all species of tiger beetles.

There are five tiger beetle species in Britain, of which the Green tiger beetle Cicindela campestris is the only widespread and common. It is an agile hunter, catching invertebrates, especially spiders, caterpillars and ants. It can be recognised by long bronze legs, metallic green body colouration, and yellow spots on the wing cases.

The Wood tiger beetle or Heath tiger beetle Cicindela sylvatica is the largest tiger beetle in Britain, with dark/brown colouration and three or four pale yellow marks on its wings. Half of the population of the Heath tiger beetle has disappeared in the last 25 years in the UK due to habitat loss. This species is under priority status on the Biodiversity Action Plan.

Publications from the Manchester Museum’s Entomology Department – 2020-21

A selection of the papers published in the last academic year 2020-21, based on or containing references to specimens from the Manchester Museum’s Entomology Department

This blog is the third one of the annual series devoted to the publications based on or referred to the Manchester Museum’s entomology collections in the last academic year. During the period from 1st August 2020 to 31th July 2021, a total of 23 papers were published by 21 researchers from 13 countries (including the UK, Russia, Ukraine, Finland, Greece, Bulgaria, Germany, Iran, China, Italy, Costa Rica, Honduras and the US). Despite (inter)national lockdowns, travel cutbacks and limited access to the collection store due to the Covid-related restrictions, the Entomology department was able to continue to support research.

The majority of the authors are associated with universities or museums, for example: Museo di Storia Naturale dell’Università di Firenze (Italy); Museo de Zoología, Universidad de Costa Rica; Zoological Museum, University of Turku (Finland); University of Nebraska State Museum (US); Department of Invertebrate Zoology of the Tomsk State University (Russia); the Altai State University (Russia) and the Manchester Museum and School of Biological Sciences – Faculty of Biology, University of Manchester (UK). Other authors are affiliated with academic research institutes (e.g., Institute for Biological Problems of the North, the Russian Academy of Sciences) and one author is from the Hong Kong Entomological Society (China).

Taxa and topics

The main topic covered in these publications included the taxonomy: viz., taxonomic reviews of various taxa (some 40%), descriptions of new species (30%), and new faunistic records (18%). Less frequent topics were ecology, morphology, surveys, book reviews and memorabilia (Figure 1).

The majority of the papers (60%) were focused on spiders (the order Araneae). Taxonomic reviews, including descriptions of new species and new synonymy, were the main topics of 14 publications. More than 80 new species were described, particularly from Central and South Asia (Figure 2). New information on species records and distribution from India, Vietnam, Afghanistan, Iran, and Sri Lanka was given.

Two papers for each of the following orders were published: Coleoptera (beetles), Lepidoptera (butterflies and moths) and Phasmatodea (stick insects). The Coleoptera papers focused on descriptions of new species and new faunistic records of the feather-winged beetles, and the ecology of one Neotropical species of the tortoise beetles. A single paper of butterflies was devoted to morphology in two subspecies of the European Swallowtail butterfly; there is also a review of an ‘Illustrated History of Butterflies of the Afrotropical Indian Ocean Islands’. Two papers devoted to stick insects included a description of new species from Vietnam and new records from China. A complete list of publications is given below.

Figure 1. Topics covered by the 2020-21 publications using specimens from the Entomology Department, Manchester Museum

Geographical scope

Publications based on Manchester Museum’s specimens contributed to the knowledge of entomofaunas in 32 countries from such regions as the Middle East, Central, South and South-East Asia, Europe (including the UK) and the Neotropics (Costa Rica). The highest number of publications is devoted to Central Asia (Figure 2).

Highlight of papers and authors

• Dmitri Logunov (Curator of the Arthropods Collection, Manchester Museum) made a major contribution as the author of 11, or nearly a half the papers published in this academic year. Most of his papers (70%) were dedicated to the taxonomy of spiders (order Araneae). Dr. Logunov diagnosed, described and illustrated 37 new species of spiders from India, Afghanistan, Tajikistan, Pakistan, as well as from other countries in the Mediterranean and the Middle East (Figure 3). Other publications included the jubilee article on Dr A.A. Zyuzin (an arachnologist and his colleague), marking his 70^th anniversary, work and achievement (Logunov, 2021c).

• Researchers from the School of Biological Sciences (University of Manchester) measured British and European specimens of the Swallowtail butterfly (Papilio machaon) to determine if sexual selection was responsible for the “tail length” (elongated part of the hindwings) in this species. It seems that the length of the tail is more related to avoiding predators and does not exhibit sexual dimorphism (Koutrouditsou & Nudds, 2021; Figure 4).

• Two new species of the rove-beetles of the genus Metolinus (Coleoptera, Staphylinidae), based on unpublished materials from the Horace Last Collection were finally described (Figure 5). These descriptions were published along with new records of this scarce genus in Papua New Guinea (Bordoni, 2021).

• The holotype of Calyptocephala attenuata (Spaeth, 1919) (Coleoptera: Chrysomelidae: Cassidinae: Spilophorini) from Costa Rica (Figure 6) accompanied with a description of a new host plant and further information of the natural history of this poorly known tortoise beetle from Costa Rica (Nishida & Chaboo, 2020).

Figure 6. The Holotype of Calyptocephala attenuata from Costa Rica, held in the Manchester Museum (from Figure 4, Nishida & Chaboo, 2020)

• Specimens of sticks insects (order Phasmatodea) from Manchester Museum were used in a taxonomic review of this group in Vietnam and China. In the two papers, eight new species and two new genera were described, as well as new synonyms and records from China (Ho, 2020; Ho, 2021).

Publications from Manchester Museum’s Entomology Department – 2019-20

Selection of papers published in the last academic year (1 August 2019 – 31 July 2020)

This post is the next of a series of blog posts summarizing research that is partly or completely based on the Manchester Museum’s entomology collections. During the last academic year (1 August 2019 – 31 July 2020), a total of 24 such papers were published. Nearly 70% of them were completed and published during the first seven months of 2020. Despite lockdown restrictions in many countries due to Covid-19, many researchers were able to continue their studies.

The Entomology Department supported more than 40 researchers and naturalists from 10 countries (Russia, Belgium, Sweden, Germany, Israel, Slovakia, Finland, India, Pakistan and United Kingdom). This support goes beyond just loaning specimens, but includes searching for and providing requested information or photographing specimens. The curator, Dmitri Logunov also provided comments/suggestions on improving manuscripts at different stages, identified specimens, especially those of spiders, and encouraged collection volunteers and associates to undertake own research and publish their results. In all papers, the importance of Manchester Museum collections as the repository of voucher/type specimens for the study of taxonomy, comparative morphology and many other topics is highlighted.

The majority of papers (Figure 1) were devoted to spiders, the order Araneae – 17 papers in total. Other taxa studied include beetles (Coleoptera; two papers); butterflies (Lepidoptera; two papers); as well as praying mantises (Mantodea), flies (Diptera) and wasps (Hymenoptera), with one paper on each group. The topics covered by these publications include the taxonomy and systematics (18 papers), including descriptions of new species and genera, a revision of some insect genera and new faunistic records. Two papers focused on faunistic surveys and two others are identification guides. A complete list of publications is given below.

Description of two Museum’s collections

Two important collections of the Manchester Museum were described and published at the beginning of 2020. One paper gives an account of a 200 year history of the British butterfly collection, discussing collectors, different collecting periods and patterns. The Museum’s British butterfly collection consists of over 12,000 specimens, representing 69 species. Most of the butterflies were collected during the 1920s, 1930s and 1970s (Dockery & Cook, 2020). Both authors are honorary staff at the Museum. They reinforced the importance of museum insect collections to encourage public interest in natural history and conservation today.

Previously unsorted spiders from southern Europe collected by Eric Duffey (a famous British arachnologist and conservationist) were identified by Prof. Rainer Breitling (The University of Manchester). Around 500 species in 42 families accounting for more than 2500 specimens are included in this paper, which also provides illustrations of selected specimens. The spiders were collected from 12 European countries with data labels providing habitat information for 120 locations (Breitling, 2020). See more about E. Duffey collection and life here and here.

Highlights of the papers

• In a revision of the genus Cissidium Motschulsky (Coleoptera: Ptiliidae – feather-winged beetles), 223 specimens from the Manchester Museum were studied, as well as specimens from the British Natural History Museum. The specimens originated from 26 countries in five continents (Darby, 2020). This research actually completes the unfinished study by Colin Johnson, the former Keeper of Entomology at the Museum. Based on morphology, the author (Dr Michael Darby) described 77 new species, and about half of the corresponding types are retained in the Manchester Museum.

• An updated checklist of four families of the order Diptera (Atelestidae, Brachystomidae, Empididae and Hybotidae) that occur in Lancashire and Cheshire was compiled by Phil Brighton. It is more than a list of species, also including information a national and local conservation status of all species, their distribution, ecology and preferred habitats. As well as museum specimens, the paper relied on several recording schemes, such as the National Empidoidea scheme, Greater Manchester Local Records Centre and RECORD (Brighton, 2020). The document provides a list of 243 species, representing 62% of the total of the British species for these families – a good proportion of these species is deposited in the Manchester Museum.

• Two papers used morphological, molecular (DNA barcoding) and ecological characters to support species designation and delimitation in two different taxa, ant-mimic Micaria spiders (Araneae, Gnaphosidae; Muster & Michalik, 2019) and Swedish paraitoid wasps of the genus Ophion (Hymenoptera: Ichneumonidae: Ophioninae; Johansson & Cederberg, 2019). The former emphasized the value of natural history information, especially documented by early naturalists and taxonomists, which is not revealed using modern techniques (Muster & Michalik, 2019).

• Descriptions of new spider species (order Araneae) and taxonomic reviews, especially at genus level, represented by nearly 70% of the publications (Figure 1). Seven papers were focused on the family Salticidae (jumping spiders), including two by D.V. Logunov, Curator of Arthropods at the Manchester Museum, and A.V. Ponomarev,  of the Russian Academy of Sciences (Logunov & Ponomarev, 2020a, 2020b). These papers present new faunistic records from Turkmenistan, Iran, Kyrgyzstan, Pakistan, Tajikistan, Uzbekistan and new species from the northern Caucasus (Russia) and Turkmenistan.

• A description of the fifth new species of praying mantis (Dracomantis mirofraternus, Mantodea: Mantidae) from the central highlands of Vietnam in the last three years, evidences the rich biodiversity of this little-known area (Shcherbakov & Vermeersch, 2020). Manchester Museum holds two paratypes of this species.

• Many Coleoptera specimens from the Manchester Museum were used to compare species between different biogeographical regions in a review of the Cryptophagidae (Coleoptera; feather-winged beetles) of Canada and Alaska. Specimens of 50 species from the Palearctic Region were used for a comparison with Nearctic species (Pelletier & Hébert, 2019).

Neither male, nor female

Weaving through mazes of ancient-looking cabinets, the ever-present scent of mothballs permeating the air, one can only begin to comprehend the breadth and magnitude of the Museum of Manchester’s entomological collection of 2.5 million specimens. Much of it was donated or bequeathed from individual collections, and as such, allows a fascinating representation of the history of entomology around the world. By studying these collections, we can not only gain insight into the insects themselves, we can reveal peculiarities about the contexts in which they were collected. In today’s blog post, I would like to introduce you to a drawer of particular interest, originating from the collection of Mr. Joseph Sidebotham.

Josef Sidebotham, the frontispiece from Grindon’s (1886) memoir

Joseph Sidebotham (1824 – 1885) was a Mancunian businessman with a broad range of interests including, but certainly not limited to, natural history (Cook, 2015). A member of numerous scientific societies and highly esteemed in his community, his collection of Lepidoptera was donated to the Museum by his heirs in 1919, and included 1,900 species of mostly British origin. At first glance, they appear relatively consistent with other individual collections of the time. The butterflies are set with their wings depressed, nearly touching the bottom of the drawers, a style of mounting which was common until the 1860s. Despite being very aesthetically pleasing, only a few are labelled with dates or locations, as many personal collectors did not regard this information as vital.

The style of butterfly mounting in the Sidebotham collection; the Manchester Museum.

Upon closer inspection, elements of mystery begin to reveal themselves. The left-most column displays Orange-tip Butterflies (Anthocharis cardamines), which are a sexually dimorphic species, meaning that males and females look different. Male Orange-tip butterflies have (you guessed it) orange-tipped wings, while the females have more inconspicuous colouration. So, what are those two specimens in the middle, each with a single orange-tipped wing?

Drawer of butterflies from the Sidebotham collection; the Manchester Museum.

Two gynangromorph specimens of the Orange Tip (Anthocharis cardamines) from the collection of the Manchester Museum.

Those individuals are known as gynandromorphs, meaning they show both male and female characteristics (gyn – female, andro – male, morph – form). Resulting from errors during early development, they are uncommon in nature, but gynandromorphy has been documented in a wide range of insects (see Narita et al., 2010 for further details), spiders (e.g., Kaston, 1961) crustaceans (e.g., brine shrimps; see Campos-Ramos et al., 2006) (and even birds (Agate et al.,2003). It is most easily distinguished in sexually dimorphic species; however the pattern of male and female tissue can differ between individuals. Bilateral gynandromorphs, such as the Orange-tips above, have a left-right split of male and female characteristics. Individuals of the same species with a more random distribution of tissues, known as mosaic gynandromorphism, can also be found.

The matching pair of Orange-tips were likely a point of pride within Sidebotham’s collection, as their opposing colouration provides a striking example of gynandromorphism, and such specimens were often favoured by insect collectors due to their rarity and unusual appearance. Besides, these specimens seem to represent one of the oldest records of gynandromorphism in Lepidoptera (Narita et al., 2010). Now, they provide the Museum with not only an educational tool, but an intriguing little piece of history.

Project – wing-shape variation in swallowtail butterflies

The Manchester Museum’s huge insect collections are used in many different ways, for instance, for research projects by staff and students of the University of Manchester. The project briefly described below is being carried out now by Lydia Koutrouditsou, a Greek Erasmus student under the supervision of Robert Nudds from FMBH.

Lydia Koutrouditsou is selecting a specimen of Swallowtail for taking a photo; the Manchester Museum.

Robert and Lydia take photographs of the museum specimens of swallowtail butterflies (both dorsal and ventral) in order to analyse and calculate their wing shapes using a technique called geometric morphometrics. The researchers are interested in two British butterfly species: Swallowtail, Papilio machaon (incl. the subspecies britannicus), and Scarce Swallowtail, Iphiclides podalirius podalirius. Both species are known to be sexually dimorphic in terms of overall size, with females being the larger. What Robert and Lydia want to investigate is whether the butterflies also differ in the shape of their wings and their tails. If it is found they are different, the study will then go on to look at the aerodynamic consequences of these shape changes.

What is a real colour of butterflies and moths, a challenge for researchers?

Many of the visitors to the Manchester Museum’s Entomology store are researchers, studying various aspects of insect diversity, taxonomy and even physical properties of their colour. A group of researchers from the New Castle University (UK) is interested in what could be a real colour of butterflies and moths seen as if through the eyes of their predators, birds in particular. Here is a brief report provided by Matthew Wheelwright (Fig. 1), a postgraduate student who is involved in this research project:

Fig. 1. Matthew Wheelwright, a postgraduate student from the New Castle University (on the left) and Phillip Rispin, a curatorial assistant from the Manchester Museum (on the right), are sorting out lepidopteran specimens for scanning.

Colour is vitally important for many aspects of insect lives. It can help them to control their body temperature, or allow them to be recognised by members of their own species. The right body/wing colour can allow insects to blend into their environment in order to hide from predators. Another way in which colour can be used to escape predation is through giving a clear message to their potential predators that they are toxic, not edible or unpleasant tasting and should therefore be avoided. Such insects are usually brightly coloured, with a mixture of yellow/orange and black stripes and spots on their wings. This phenomenon is known as warning coloration (=aposematism). Some other species which occur in the same areas can also benefit from these warning signals by evolving to look like these not edible species; this phenomenon is known as mimicry.

Fig. 2. Butterflies and moths from the collection of the Manchester Museum sorted out for scanning by means of a hyperspectral camera.

The purpose of our study is two-fold. Firstly we want to find out what makes a good pattern of warning coloration and secondly to discover how closely a mimic must resemble a model having warning coloration (=aposematic model) in order to deceive predators into thinking that they are the same species. In order to do this, we need to know how these patterns look to predators (many of which have different visual systems to humans). We therefore take pictures of specimens from various collections from across the globe, including the entomology collection at the Manchester Museum (Fig. 2), using a hyperspectral camera (Fig. 3). This camera allows us to look at the exact colour spectrum of the specimens, including the amount of Ultraviolet (UV) reflected by them. The latter aspect is very important, as many predators, such as birds, can see in UV.

Fig. 3 A hyperspectral camera at work, scanning the Black Witch Moth (Ascalapha odorata) from the collection of the Manchester Museum.

We then used models of predator visual systems to quantitatively compare the colour and pattern of aposematic species to non-aposematic species and the patterns of mimics and models to predict how the predators could perceive them and therefore react to them. In other words, we try to see butterflies and moths through the eyes of insect predators and hope to find out whether insects that look aposematic to us (or their mimics) are seen in the same way by their predators.

Two images of the Orange Sulphur (Colias eurytheme) given below (Fig. 4) show how the butterfly appears to humans (on the left) and to a bird (on the right). Orange Sulphur looks iridescent under the UV, and the false colour image on the left contains the purple representing where the UV is the brightest and seen to birds. The image was kindly created for us by Olivier Penacchio of the University of St. Andrews.

Such research project would be impossible without access to museum specimens from large entomological collections such as that of the Manchester Museum. So we would like to take this opportunity to thank Dr Dmitri Logunov and Phil Rispin for their assistance and generosity with the loan of some specimens.

Taking Wing: curating a collection of Venezuelan hawkmoths

The following report has been prepared by Claire Miles, Honorary Curatorial Associate at The Manchester Museum.

Manchester Museum purchased the Adams and Bernard collection of 300 Venezuelan Lepidoptera in April 1976. Since then, if a curious curator removed the lids from the cardboard boxes to peer at the ghostly silhouettes in their translucent paper packets, the lids were always replaced. Now, thanks to funding from the Natural Science Collections Association (NatSCA), part of this collection – around 175 hawkmoths – can be set out, identified, catalogued, and made useful. This blog is a brief summary of progress so far.

Tantalising shapes – the moths in their paper packets.

In the paper packets, the hawkmoths lie with their wings folded together. With wingspans of up to 17 cm, setting the hawkmoths out will take up quite a bit of expensive storage space. Thanks to the NatSCA funding, the necessary glass-topped drawers can be purchased for the Entomology department’s new metal cabinets.

Entomology cabinets at Manchester Museum.

The entomology collections at Manchester Museum contain more than three million specimens including about two and a half million insects (Logunov & Merriman 2012; Logunov 2010). They already hold around 2000 hawkmoths (Sphingidae) representing around 270 species: 700 in the British collection, 850 in the C. H. Schill Worldwide Lepidoptera collection and 370 in the P. Schill Palaearctic Lepidoptera collection.

A drawer of the Death’s-head Hawk-moth, Acherontia atropos, in the British collection.

To put this in perspective, there are about 1500 known hawkmoth species worldwide, and this collection is a drop in the ocean compared to the Natural History Museum’s holdings of 289,000 Sphingidae. Curating and identifying the Adams/Bernard collection serves multiple purposes. It will extend the range of Manchester Museum’s Sphingidae, it will increase the accessible Sphingidae by about 9%, it will hopefully add some species new to the collection (and who knows, possibly completely new species), it will improve access to the collections, and it will improve their storage and security. In addition, I get to hone my practical skills setting the moths, with expert guidance from Phil Rispin, Curatorial Assistant in the Entomology Department.

Some of the hawkmoths have extremely long tongues. They pollinate flowers which provide nectar at the bottom of correspondingly long flower tubes, such as orchids and petunias.

Hawkmoths are fast-flying moths with streamlined bodies, present on almost every continent except Antarctica. They are pollinators as adults, and can be agricultural pests as larvae, which makes them ecologically and economically important, and their relatively well-understood taxonomy and fast response to environmental changes makes them useful environmental indicators (Camargo et al., 2016). This collection gives a snapshot of the species that were present in Venezuela 40 years ago when Mike Adams and George Bernard collected them in May 1975. This was one of a number of expeditions they mounted to Columbia and Venezuela in the 1970s and 80s, searching the high montane cloud-forests of the northern Andes for Pronophiline butterflies (a subtribe of the subfamily Satyrinae), on which they published a number of papers. The hawkmoths were collected in a region 24km north of Altagracia, Miranda State, at altitude 700m; from Guapo Dam, Miranda, and from Rancho Grande, Aragua, at altitude 1090m. The Museum’s Annual Report of 1976 describes the pair only as ‘University Zoology students’ at the time, although it appears they were recent graduates when they started their explorations (Adams, 1984).

Out of their packets, the hawkmoths were found to be in pretty good condition and the colours are remarkably fresh. Six weeks into the project, we have developed a routine – Phil puts the moths to relax in a damp atmosphere at the beginning of the week, and I (generally working one day a week) set them out at the end of the week.

Each moth is set out, pinned down and left to dry for a fortnight (Adhemarius species shown here).

Once set, the collection data label and accession number are added to the pin. 80 moths have been set so far, and at a quick count those represent at least 20 species. The next step will be to identify them. Ultimately, the aim is to collate the information on all the Manchester Sphingidae collections into a single resource, and these stunning moths will be available for research and provide a fantastic resource for the museum’s teaching, displays, public events and engagement activities.
