One of the most important ways of expressing the scientific value of natural history collections is the production of collection-based papers. This blog explores our commitment to making the arthropod collection of the Manchester Museum available for research and overviews the papers published between August 2018 and July 2019. In all cases, the Manchester Museum is used as a permanent depository of the studied type and voucher specimens.

In total, 28 scientific papers based on specimens or data from the Museum’s Entomology Collection were published by researchers from nine countries (France, Belgium, Russian, Brazil, Poland, China, Iran, South Africa and the UK). The researchers were from research institutes, museums and universities, including, Institute of Systematic and Ecology of Animals (Russia), Instituto Nacional de Pesquisas da Amazonia (Brazil), Entomological Society (China), Insect Centre (Russia), Muséum des Sciences Naturelles et de Préhistoire de Chartres (France), University of Wroclaw (Poland), University of Tehran (Iran), The University of Manchester (UK) and the associated staff of Manchester Museum.

The University of Manchester staff and volunteers (Professor Laurence Cook, Michael Dockery, Claire Miles, Diana Arzuza, and Dr Dmitri Logunov) published seven articles, describing collectors and important and unusual collections, for example:

  • The entomological legacy of Robert Wylie Lloyd (1868–1958), who made a major donation to the Entomology Department; the extent of his donation (British and European beetles and butterflies) and his motivation as a naturalist are discussed (Cook L. 2019).
  • An overview of the John and Francis Murphy Spider Collection, the largest one ever acquired by the Museum and its description as a valuable resource for arachnologists (Arzuza Buelvas D. 2019).
  • A complete summary of the Sphingidae (hawkmoths) collection held in the Manchester Museum’s Lepidoptera collections, incuding a full species list (British and worldwide) and information of collectors and collections (Miles, 2019).
  • The Lepidoptera collection of William Raymond Wooff (1929–2006), the content of this unusual collection (butterfly/moth wings mounted on index cards), with reliable data about distribution and habitat, is explored in this paper (Dockery M. & Logunov D.V. 2018).
  • Examples of industrial melanism and its rapid adaptive response to a changing environment in Britain in 19th century using specimens of the Peppered Moth (Cook L. 2018).
  • An obituary of Dr Eric Duffey, British arachnologist, ecologist and conservationist; details of his professional life and contribution to the Manchester Museum’s Entomology collection are given (Logunov D.V. 2019).

Topics covered by the publications include taxonomy, systematics and phylogeny (18 papers), including descriptions of new species and genera, and new faunistic records. Three papers were focused on surveys and one is an identification guide. Taxa in such publications included species of Araneae (spiders), Coleoptera (beetles), Lepidoptera (butterflies), Phasmatodea (stick insects), Mantodea (mantis) and Trichoptera (caddis flies), see Figure 1.

Figure 1. The taxa covered by papers published between August 2018 and July 2019 using the Entomology Collection of the Manchester Museum. ‘Other’ includes non taxonomic, museological publications, such as those describing collectors and/or collections and their history.

The order Araneae (spiders) is the group with the most papers published (13 in total), this is mainly due to the taxonomic expertise and scientific connections of the current Curator of Arthropods, Manchester Museum. Dr Dmitri Logunov has described two new spider species, including a jumping spider from Hong Kong that mimics lichen moth caterpillars and is named after the famous US childrens’ author, Eric Carle, who published the book ‘The Very Hungry Caterpillar’ (Logunov D.V. & Obenauer S. 2019). This new species was discovered during a City Nature Challenge event in a park on the outskirts of Hong Kong. See here for more information.

Coleoptera represented the second taxa with most papers published (7 in total). The papers included descriptions of new species from the Himalayas, new records and identification keys from the Brazilian Amazon Region, a monograph of the Afrotropical Cassidinae with description of seven new species, and taxonomy reviews and new species from southern Asia.

The order Trichoptera (caddis flies) featured in phylogenetic research and in a revision of a ‘chimeric’ European genus. The order Phasmatodea (stick insects) featured in a description of three new stick insect species from Vietnam, and Mantodea (praying mantises) in the description of a new genus and two new species of praying mantis from the Vietnam.

All the publications were peer-reviewed. The most popular journals for these publications were Arthopoda Selecta (specialised in morphology, taxonomy, life histories, zoogeography, phylogeny and evolution of arthropods); Zootaxa (journal for animal taxonomists) and the British entomological journal ‘Entomologist’s Monthly Magazine’ published four times a year.

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.

Image_01_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.

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?

Image_04

Image_02

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.

Manchester’s urban green spaces and parks provide homes to a vast array of wildlife, and The Friends of Fletcher Moss Park and Gardens are inviting everyone to lend a hand at their BioBlitz event on Saturday 18 May – an exciting race against the clock to discover, identify and record as many species of bird, insect, mammal and plant life as possible.

The BioBlitz will have a particular focus on the insects that fly, buzz, wriggle and crawl in the habitats around the park and within the nearby Mersey Valley, and there will be experts on hand from a number of organisations including Manchester Museum and the RSPB to help identify what is found. The data recorded will be shared with Greater Manchester Local Records Centre and the National Biodiversity Network and will be used to measure the impact of future conservation work, undertaken in partnership with Manchester City Council, at the site. 

At the start of the event there will be a rare opportunity to observe nocturnal insect species up close, and throughout the day there will be guided walks suitable for all ages that will showcase the range of species that can be found at Fletcher Moss Park. More information about the times of the walks can be found by visiting rspb.org.uk/events and searching for events in Greater Manchester.

Families can drop in to take part in fun activities, including pond dipping, minibeast hunting and worm charming – these activities count towards the RSPB’s Wild Challenge, a digital rewards scheme to encourage families to get closer to nature all year round by completing fun activities that will help wildlife in their own back garden and the great outdoors. For more information about the Wild Challenge, visit rspb.org.uk/wildchallenge

Venue: Fletcher Moss Park and Gardens. Use the Millgate Lane entrance, M20 2SW. Activities will be signposted upon entering the park.

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.

The Manchester Museum has very large collections of British insects, numbering some 750,000 specimens. Of them, the British Hymenoptera (bees, wasps, ants, and the like) collection numbers some 45,000 specimens representing 3,200 species (see Logunov, 2012). Unfortunately, the collection is in need of a thorough revision regarding its nomenclature and records in the Museum’s database, as some of the species names it contains are up to 60 years old, being thus out of date.

Megan Baker, a MSc student from the University of Manchester (Fig. 1), started to work on this project. One of her main roles includes updating the outdated nomenclature with modern names based on a much more recent British Hymenoptera checklist, published in 2014. Megan is also responsible for transferring the collection to newly acquired modern drawers and cabinets, relabelling and expanding the collection as she goes, leaving space to allow for new acquisitions (Fig. 2). Alongside this, she is also updating the database records with the newly added information, including any changes to the nomenclature, location, or data/ID labels. During her time at the museum, Megan has also been responsible for processing a newly obtained collection of some 900 identified specimens from Richard D.C. Jones (19432018) and documenting it in the Museum’s database. Later, this collection will be amalgamated with the main British Hymenoptera collection.

This is what Megan said about her work in the Manchester Museum: “Through my work at the Museum I have gained an increased knowledge of the taxonomy and identification of Britain’s Hymenoptera, as well as an increased familiarity with many taxa. These tasks have also provided vital experience of working with entomological collections, as well as an insight into how such large and important collections are stored and cared for.

The Manchester Museum’s Entomology Department has lots of opportunities for volunteering for anyone who could be interested; enquires are to be addressed to the Curator of Arthropods, Dr Dmitri Logunov.

Surely, there are no other living things that rival insects in their vast variety in shape and form. One of the most spectacular group of insects is Lanternflies or Lantern Bugs (family Fulgoridae, order Hemiptera) distributed in the tropics of both the Old and New Worlds (see here for images). The Lanternfly collection at the Manchester Museum is not particularly large, consisting of 150 specimens that belong to 34 identified species (see Allnatt, 2013, for further details).

The following story has been prepared by Kasia Majewski, the Curatorial Assistant within the Manchester Museum Vivarium, whose background is a mix of herpetological (reptile and amphibian) and Entomological work. One of Kasia’s entomological idols, and an inspiration for her passion in ecology, is Maria Sibylla Merian (1647-1717), one of the first naturalists to observe insects directly, make associations between different insect species and host plants, and capture these interactions in stunning colour through her coloured plates. Mrs Merian was not only arguably the first female entomologist, but one of the first naturalists who was also a professionally trained artist, coupling her carefully written observations of species with her mesmerizing illustrations.

Many of her scientific observations are still recognized and valid today, however one story regarding a particular species has always captured people imagination. Fulgoridae, or Lanternflies, are tropical, often colourful flying insects with long protrusions coming from their heads, giving their bodies a uniquely triangular appearance when sitting at rest with their wings closed. In this position, they could be considered lantern shaped, but it is not from this form that they received their name. Across the world where Lanternflies are found, so too are ancient stories of their little bodies lighting up at night from their bright shining protruding “noses”. Maria Sibella Merian was one of the first Europeans to describe this behaviour during her time in Suriname. She wrote that she was presented with a box of live lanternflies, which produced “a fiery light so bright that she could read by it” from their unusually elongated heads (Fig. 2). Given Merian’s penchant for attention to detail, this account is intriguing.

More intriguingly, however, while these stories of light emitting flying lanterns have persisted through generations of native tribes in areas where lanternflies are found, from South America to Southeast Asia,  modern entomologists have never recorded any species of Fulgoridae producing any kind of bioluminescence (or here), and the function of that whimsical elongated “nose” remains a captivating mystery…

Of the 32 orders of insects 18 contain members that are carrion-feeders. Most of them are beetles and flies. Because carrion is a limited but valuable food resource, and quite unpredictable in distribution, insects, vertebrates and microorganisms compete for it. A clear characteristic of carrion-feeders is the ability to find and secure a suitable carcass quickly and to make efficient use of it.

In the northern hemisphere, the dead bodies of small mammals and birds are used primarily by burying beetles (Nicrophorus species, family Silphidae), which compete effectively with carrion-eating mammals. For instance, at the Biological Station of Michigan University (USA), scientists laid 780 fresh bodies of dead house mice on the ground in a hardwood forest. Within 24 hours 95% of the bodies had been discovered! Of them, 94% had been found by burying beetles and only 6% by scavenging mammals.

Male and female burying beetles form parental pairs concealing and maintaining carrion while also taking care of and raising their offspring (see Figure). A pair of adults buries a carcass of a dead animal, clean it from fur/feathers, destroys eggs/larvae of flesh-eating flies, and prepares a meat ball from it. The ball is protected from rotting by anal secretions from the beetles that kill bacteria. After mating, the female lays 4 to 30 eggs in the soil near the carrion. The young larvae that hatch from these eggs are fed by the parents that ingest flesh from the carrion and regurgitate partially-digested food directly to their mouthparts. The beetles interact with their larvae much as a mother bird interacts with her nestlings: when a parent approaches larvae, they rear up and make ‘begging movements with their legs’ asking for food. As the larvae grow in size, they beg less often and start feeding on their own. After one to two weeks, the larvae pupate in the soil, and a few weeks later new adult beetles emerge. The mother stays with her offspring until they are ready to pupate, while the male leaves a few days earlier.

The story is partly based on the book by G. Waldbauer (2003) ‘What good are bugs?’, Harvard Univ. Press, 366 pp.
