Manchester Museum is part of the University of Manchester and one of the UK’s leading university museums, holding more than 4.5 million objects and specimens, ranged across nature and culture. The Museum has eight main permanent galleries that reflect its main mission to build understanding between cultures and a more sustainable world. Here is a brief survey of the Museum’s gallery called ‘Nature’s Library’.

Natural history museum collections include specimens from zoology, botany, entomology, palaeontology and mineralogy, as well as documentation associated with them. Recent estimates suggest that the number of natural history specimens in British museums exceeds 100 million. The vast majority of such collections (c. 95%) are kept in storage, behind the scenes (Fig. 1: on the left). But does this mean that these collections are not used? Far from it, we care for these collections as an irreplaceable resource for research, education and inspiration. Natural history collections act as ‘libraries’, in which a separate specimen can be seen as a letter or word, and an individual collection as that of a paragraph or section in a giant ‘Book of Knowledge’. The Nature’s Library gallery why we have natural history collections, where they came from, why we continue to keep them and collect more, how such collections are used, and why are they still relevant today?

Natural history collections are the result of the curiosity and private passions of thousands of people, each with their own motivations for collecting. Living things, shells and rocks are often very beautiful or intriguing to look at, with endless variety of shapes, colours, patterns and textures (Fig. 1: on the right). Each specimen in the Museum is identified by a unique ‘accession number’. Information on each specimen is recorded in a Museum’s Register book and database. The Manchester Museum continues to collect, because collections have to be relevant to people and their needs today (Fig. 3).

The Manchester Museum is part of the University of Manchester, and has been open to the public since 1891. Thousands of schoolchildren, students and researchers use the Museum each year, for study, research and enjoyment (Fig. 4). The Museum is a unique place where visitors can see real objects, have access to experts and develop their own curiosity. Historic natural history collections are a rich resource of historical information about people, places and links to our colonial past. Designers and artists draw inspiration from their remarkable variety of forms, colours and patterns, exploring new ways of seeing and presenting the world around us. The Museum has about 250 enlarged models of plants and animals. These were used to teach students in the late 19th and early 20th centuries, and are still used for outreach programmes and undergraduate teaching today (Fig. 5).

The fundamental value of natural history collections is related to our understanding of the Earth’s diversity. The Manchester Museum holds large collections that were assembled by researchers who studied particular organisms and described new species. In the gallery you can find some of the thousands of specimens collected by HMS Challenger, during the first scientific expedition (1872-76) to explore the deep ocean (Fig. 6).

Natural history collections offer a unique opportunity for understanding the world around us, providing data over a vast time span ranging from millions of years ago (minerals and fossils) to the present day. These data reveal changes in environmental conditions and their consequences from deep time to within human history, and help us build up a better, sustainable future (Fig. 7).

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).

Supporting local communities: a “springwatch” event at the Royton Linear Park, Oldham

Banner of the Springwatch Event at Royton Linear Park, May 2022

On Sunday 15^th May 2022, as part of the event “Springwatch” organized by the community group called ‘Friends of Royton Linear Park’, Dmitri and I were invited to participate and talk about insects. The main idea was to develop interest in wildlife among local residents of this park in Oldham, which used to be a railway track.

Dmitri Logunov (Curator of insect collections at the Manchester Museum) and Diana Arzuza (Curatorial Assistant) with local residents during the “Springwatch” event at Royton Linear Park

The weather was perfect and the event itself was really a success. As soon as we set up our display table, some 40 minutes earlier than the official opening of the actual event, many interested visitors started to appear and engage with us. We shared stories about British insects, habitats and facts about their life cycles and natural histories, as well as showing some British endangered species and, of course, some showy foreign beauties. Other organizations, such as the Royal Society for the Protection of Birds – RSPB with birdwatching activity for kids and families, also supported this event. The hedgehog conservation group was talking about chances to create a more attractive environment for hedgehogs and discussing them with the local recording group.

The day was packed with many other activities for adults and children, including craft making, face painting and even tree-planting. There were also stalls with home-baked cakes, plants and goodies for selling, all towards fundraising for the maintenance of the Royton Linear Park.

This community group was established a year ago and have been working to keep this area free of litter/wastes and more family friendly. There are plans for different sections of the park, including incorporating art in tunnels and bridges. However, the most ambitious plan is to create a wildlife corridor connecting this linear park with other green areas/spaces in Oldham and Rochdale; ultimately, improving this green space for the benefit of the local residents and wildlife.

Many thanks are due to Shirley Brown (the leader and organizer of the group and the event) for inviting us to participate. We were thrilled by positive responses from the visitors and amazed by how many people visited the Manchester Museum and remembered our Spider Crab.

If anyone reading this post wants to be involved and support Shirley Brown and her small group of enthusiasts, just join the Friends of Royton Linear Park on Facebook.

Golden Standards of the Manchester Museum

When a taxonomist is going to name a new species, s/he must designate a particular specimen as the reference standard of that species. Such specimen – one particular butterfly, pressed plant or mineral – is called the name-bearing type (=holotype). It is permanently associated with the published scientific name and official description of the species. Type specimens serve as the primary and unique references for all known species names. They play a key role in stabilizing the use of species names. The type must be unambiguously designated, because it is required for identifying other specimens or validating the use of a name. Types are deposited in reliable natural history museums, properly cared for and made available to researchers that need to examine them.

Similarly to the International Bureau of Weights and Measures which establishes a common understanding of such units as length, mass, time, electric current and others, natural history museums keep type specimens to provide unequivocally links to species names. A number of the type specimens in a particular museum reflects its scientific significance and international standing. The Manchester Museum holds some 22,000 types representing over 8,000 species names, and the number of the types is growing. The Museum is one of the most important taxonomic depositaries in the UK.

Traditionally, type specimens are kept in behind-the-scenes stores of natural history museums and never displayed. Their primary role is to support taxonomic research. Below a selection of type specimens from different collections of the Manchester Museum is presented.

Well, the work of a taxonomist could apparently be compared even to that of a detective.

Our visitors – studying net-winged insects: diversity and evolution

James Jepson working with Manchester Museum’s collection of Neuroptera. © The Manchester Museum.

The Manchester Museum welcomes all kinds of visitors: art and design students, members of local natural history organisations, school and college students, family groups, etc. Yet, about half of our visitors are researchers working on many interesting, often inter-disciplinary projects. For instance, Dr James Jepson (on photo) is a palaeontologist from the University of Manchester, looking at the evolution of insects, in addition to studying the evolution of lacewings and their allies (order Neuroptera). He is also involved in studying these insects in Cheshire and Lancashire and is responsible for the national recording scheme of these insects. Below is James’ brief report on what he does and how he uses the Manchester Museum’s insect collections.

_______________________________________________________________

I have the pleasure of regularly visiting the entomology collections at the Manchester Museum to gather data for three projects that I am currently undertaking. The first being part of my postdoctoral research on insect relationships and evolution. I am using the specimens in the collection to code morphological characters, which I will then use to create a phylogeny to show the relationships of extant and fossil insect orders. From this phylogeny, I will be able to investigate the evolution of insects throughout geological time, from their beginnings to the present day.

The second project relates to the British Isles Lacewing and Allies Recording Scheme. I have recently become the co-organizer of the scheme, which we relaunched earlier this year. The scheme takes in records of the orders Neuroptera (Lacewings, Waxflies, Antlions & Spongeflies), Raphidioptera (Snakeflies), Megaloptera (Alderflies) and Mecoptera (Scorpionflies & Snowfleas) found in England, Scotland, Wales, and Ireland. If you want to know more about the scheme, and how you can contribute, please visit our website. At the museum, I am documenting the collection of British lacewings and allies in the collection for addition into the recording schemes database. Museum collections hold very important data not only on recently collected specimens but also on specimens collected in the past. These historical collections give us information on past distributions of species and can help us assess any changes that have happened over time.

The final project is looking at the museum’s collection of Neuropterida (Neuroptera, Raphidioptera, Megaloptera). In addition to the British specimens, I will also be looking at specimens from other countries, like India, Costa Rica, and others. I will be putting a name to the unidentified specimens and checking the identity of the others to take into account recent changes in neuropterid taxonomy.

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.

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).

A month ago, thanks to the CapCo grant, the Manchester Museum purchased a new stereo microscope (Olympus, SZX 16) with a digital colour camera (DP27-CU-1-2), which is designed for photographing small and diminutive objects. Two weeks ago, we had a training session and here is the first image taken by means of this microscope and camera (see above). We are about ready to start a large project aimed at the digitisation of tens of thousands of diminutive insects, including type specimens of the Feather-winged Beetles (Cryptophagidae), Fungus Beetles (Latridiidae) and many other small-sized groups, deposited in the Manchester Museum.

Star objects of our collection – Bullet Ant, feared and poetized

Bullet Ant (Paraponera clavata) from the collection of the Manchester Museum; its sting is arrowed. © Manchester Museum.

Many species of ants (family Formicidae) hold a great fascination for the human from the ancient time. For instance, Pliny the Elder believed that ants are the only living creatures besides man that bury their dead. Ants have been greatly admired for the qualities of intelligence, hard work, good organisation, and harmonious social life. Moral lessons for mankind were frequently drawn from various aspects of their behaviour. In the Old Testament, one can find the following wisdom: ‘Go to the any thou sluggard; consider her ways and be wise: which, having no guide, overseer, or ruler, provideth her meat in the summer, and gathereth her food in the harvest’. Ant colonies in their anthills could be seen as both a microcosm of man and his world, and a positive example of communal cooperation. However, not all ants have acquired such a positive reputation among humans, some of them are feared: e.g., the Bulldog Ant (Myrmecia sp.), or the African Driver Ants (Dorylus spp.), which sometimes are depicted as merciless invaders that consume all creatures in their path, especially in Hollywood horror movies; for general information about myrmecophobia (=fear of ants) see here.

One of the feared ant species is the Bullet Ant (Paraponera clavata), a large black ant that can reach a length up to 2-3 cm (see photo). It is the largest ant of Central and South Americas, known from the Caribbean lowlands of such countries as Honduras and Costa Rica, southward to Peru and Brazil. Ants live in large subterranean colonies with the entrances situated at the base of large trees. Each colony contains from 700 to 1400 worker ants: i.e., members of the worker caste, all are infertile females. Workers are solitary hunters that search for their prey (various smaller insects) from ground level up to the canopy, and can be seen and encountered during both day- and night times; for more information about Bullet Ant see here and here.

This ant should be avoided as it can inflict an extremely painful sting (its sting is arrowed in the photo above). The venom of the Bullet Ant contains poneratoxin, a neuropeptide causing an acute pain and local paralysis, but not fatal to humans. The regional name of Paraponera clavata in Costa Rica is ‘hormiga bala’, meaning ‘bullet ant’. People who have been stung by this ant say that its bite feels like a bullet wound, or even like a 3-inch burning rusty nail in your heel; the pain can last for 24 or more hours, and a person may need 2 weeks to recover from a single sting. If someone scored various stinging insects like bees, wasps and ants on a pain scale from 1 to 4, еру Bullet Ant would surely get the highest, 4-point score. Hence, it is hardly surprising that Native Americans of the Yurok tribe in California believe that ants became venomous by catching chips in their mouths from a mythical burning arrowhead. In Brazil, members of the indigenous tribe Satere-Mawe, who reside along the border between the Pará and Amazonas states in Brazil, use Bullet Ants and their painful stings in a ceremony of initiating young men into adulthood; watch the video below.

Despite some undeniably negative qualities (from the point of view of humans, of course) that can be attributed to bullet ants, the ant still inspires some naturalists to poetize them. Here is the latest limerick dedicated to the Bullet Ant by Richard A. Jones (2021):

The bullet ant feared no attacker,

Because with her sting she fought backer.

The venom she dealt

Was the worst to be felt –

A true hypodermic fire-cracker.

Star objects of our collection – the Ox Beetle

To celebrate the 2021 Year of the Ox in the Chinese calendar, we have chosen the Ox Beetle (Strategus aloeus) as a star object from the Manchester Museum’s Entomology collection. It is a species of the rhinoceros beetles from the family Scarabaeidae from the Americas. The male Ox Beetle has three characteristic horns on its thorax, two at the back and the longer one at the front, resembling Triceratops. This species is also called Elephant Beetle, Hercules beetle or Escarabajo Buey (in Spanish).

Adults of the Ox beetle can grow up to 2.5-3.8 cm long and live four to six months only. They feed mainly on various fruits and flowers, and are very active during the breeding season from May to November. Interestingly, the male Ox Beetles have two varieties, “major” and “minor”. Major males have three large horns on the thorax used for mating competitions. Minor males have shorter horns. Female Ox Beetles have a small raised area (a very short horn) used mainly for digging, not for fighting. Females lay their eggs in rotten wood or roots on sandy soil, with dried leaves sometimes added to maintain the right temperature and secure hatching.

Larvae or grubs of Ox Beetles feed on roots with their powerful mandibles. Larvae are about 5 cm in size when curled, double if straightened. The larval stage takes about 4-6 months to develop into a pupal stage and almost a year to develop into an adult. Pupation may be affected by weather conditions, but this stage can be shortened when maintained in warmer environments (for example, when bred in captivity, for a manual see here).

This species is the largest and most common beetle found in the south-west part of the USA, from Arizona to Florida. It occurs throughout Central America and in parts of South America (especially in Colombia, Ecuador and Brazil).

Records of the Ox Beetle in the Americas; based on Naturalista Colombia.

Larvae of Ox Beetles are considered pests, causing damage to plantations and gardens. For example, in Colombia, larvae affect recently planted oil palms due to the use of large amount of decomposing material as part of the planting process. In Mexico, larvae can affect new plantations of Blue Agave, Agave tequilana, a key ingredient of tequila. However, adults and larvae of the Ox Beetle also play a vital role in recycling organic matter in tropical ecosystems.
