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.

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.

In late January 2017, Ms Eleanor Smith of Wilmslow (Cheshire, UK) visited the Manchester Museum and brought a medium-sized spider (see Fig. 1) that was found alive in a bunch of bananas, in a supermarket (Lidl) near Wilmslow. As she was told, the bananas on which the spider was found were delivered from Colombia. Unfortunately, the spider was already dead because Eleanor had kept the jar with the spider in a fridge; far too cold for such a tropical creature. The specimen was found to belong to what is commonly known as ‘Banana Spiders’. It was a mature female that was identified as Sadala sp. in the family Sparassidae, huntsman spiders. The specimen is now deposited in the Manchester Museum’s spider collection (accession number G7585.1).

Spiders that are incidentally imported with bananas are commonly called ‘Banana Spiders’. However, this common English name is rather misleading, as it is used for quite a number of different spider groups.

In North America, this name can be applied to Golden Orb-web Spiders (Nephila species, family Nephilidae – most commonly Nephila clavipes); see also here and here. The reasons why this species is called ‘Banana Spider’ remain unclear, for there is no obvious connection between the spider and bananas – could it be because of the banana-shaped abdomen of rather large females? By the way, some Nephila species are edible and even considered a delicacy by indigenous people in New Caledonia and Australia, for instance, Nephila edulis (and here).

The wandering spiders (family Ctenidae) are regularly called ‘Banana Spiders’ as well (see Vetter et al., 2014). Some of them have even acquired a very bad media-reputation as deadly venomous species: for instance, the Brazilian Wandering Spider (Phoneutria fera). Alas, most of online media reports – for instance, MailOne(24 June 2015) or Independent(21 September 2016) – cannot be taken seriously, as they fail to even provide a correct identification of the spiders found on bananas.

In reality, to date, there has been only one published record of the Brazilian Wandering Spider as being imported to Europe (Germany) in 1950s, but yet the identification of that specimen causes doubts. The majority of existing records of “Brazilian Wandering Spiders”, both from Europe and from North America, are likely to belong either to the harmless Central American spider genus, Cupiennius (Ctenidae), or (much rarer!) to other Phoneutria species – most commonly, to Phoneutria boliviensis, a medically important wandering spider from Central America.

By far the most common spider group being imported with bananas is the pantropical huntsman spiders (family Sparassidae), also called ‘Banana Spiders’. In total, 13 species of huntsman spiders have been identified of those imported with bananas and other international goods to Europe. At least five species of huntsman spiders have been reported as being imported with bananas to the UK (Browning, 1954; Wilson, 2011): Barylestis occidentalis, Barylestis scutatus, Barylestis variatus (all from Africa), Heteropoda venatoria (from SE Asia, but now pantropical) and Olios sanctivincenti (from Asia). The commonest of them is Heteropoda venatoria, which is even established indoor in some regions of southern Europe (see Fig. 2). Yet, a real number of imported huntsman spiders might be much higher; Sadala sp. which was mentioned above (Fig. 1) is a new record from this group.

The spider collection of the Manchester Museum contains a number of samples of huntsman spiders collected from bananas in Manchester and its vicinities; for instance, from the Manchester Market Street in June 1912 or April 1931 (Fig. 3).

Fig_03_Banana Spiders

Several spider species that were obtained from the Manchester Open Air Market from imported bananas; the Manchester Museum.

Overall, a number of alien spider species that are imported with bananas and other international cargo to Europe or North America is rather high. For instance, Nentwig (2015) listed 184 species that have been imported to Europe over the last 200 years; of them 47 species have established there in and around human buildings. Vetter et al. (2014) identified 135 spider species imported to the USA in seven years (between 2006 and 2010). Although in the past banana or other fruit shipments were the main pathway of introduction to Europe, today potted plants and apparently container shipments in general are more important. It is suspected that due to the increasing international trade volume and climate change, in the next decades at least one new spider species will be introduced to Europe and established there annually.

The Golden Orb-Weaving spider – Nephila clavipes (Linnaeus, 1767) of the family Nephilidae – is known from USA to Argentina. In Costa Rica, it occurs in lowland and premontane tropical rain forests. Females make large aerial webs in which they usually occupy the centre. Orb-web spiders are effective predators and can easily subdue prey that is significantly larger and heavier than the spider (see on photo).

Two females of Nephila clavipes with prey; Costa Rica.

Two females of Nephila clavipes with prey; Costa Rica.

One of the most peculiar characteristic of this species, as well as of other Nephila species, is an extreme sexual size dimorphism, where dwarf males can be many times smaller and lighter than the females (see on photo). Numerous hypotheses have been proposed to explain the factors that may give rise to such size dimorphism in spiders. Some of them are briefly discussed here.

In the case of Nephila, it is argued that that large size in females could be driven by selection on female fecundity (= the potential reproductive capacity), acting to increase the number of offspring produced. With the high level of juvenile mortality, the production of larger numbers of offspring is crucial for survival of the species. Thus such size dimorphism is almost always due to female gigantism rather than male dwarfism.

As was demonstrated for some African species [e.g., Nephila pilipes (Fabricius 1793)], females continue to grow after reaching maturity. The females mature at varying body sizes and instars and then continue to grow by molting the entire exoskeleton except their copulatory organs (=genitalia). Apparently, this is why in Costa Rica Nephila clavipes is represented by mature females of markedly variable body sizes (although, to date, a post-maturity molting has not been described for this species).

In a short video presented below (courtesy of Alex Villegas, Costa Rica) it is shown how a dwarf male of Nephila clavipes is approaching a giant female in its attempts to mate, alas unsuccessfully this tiem. Indeed, the male is to be careful in order not to be mixed up by the female with a potential prey.

On the second day of our field trip to Iceland, we visited the interesting site lying in the southern municipality of Reykjavik, called Garðabær, which literally means ‘Garden Town’. We walked around the beautiful Lake Urridavatn surrounded by boggy meadows full of sedge, dwarf bushes (like blue berry) and cotton grass (see on the photo).

On the meadow side of the path to the lake we found a plastic cup thrown by someone a few days ago. Incidentally, the cup, which was partly filled with rain water, became a deadly trap to insects and spiders. Having inspected the content of the cup I found two specimens of crab spiders (Xysticus sp.; male and female), one specimen of the ground beetle (family Carabidae) and one harvestman (family Phalangiidae). So, the cup ‘worked’ exactly in the way as true pitfall traps (see also here) that are used by scientists for ecological surveys. A poor thinking or maybe carelessness of someone who threw this plastic cup away instead of dropping it into a waste bin resulted in some casualties of minibeasts. Throwing a plastic cup (or any unwanted plastic item) away is hardly seen as a great deal or an action causing any threat to wild life. However, my short and simple story seems to say otherwise. In simple words, it reminds us that recycling waste is essential to both natural environment and humans, minimizing an unnecessary risk of damage to the environment and helping out our planet be a better place to live in. More about recycling can be seen here and here.

Harvestmen (Opiliones) represent a diverse group of arachnids, with more than 6,500 species described worldwide; see here for a complete list. Everyone seems to be familiar with these animals which have an oval/round body and long-long thin legs; this why their English common name: ‘daddy-long-legs’. However, there are short-legged species as well. The harvestman fauna of the La Selva Natural Reserve (Costa Rica) consists of about 40 recorded species, half of which remain unnamed yet (Proud et al., 2012).

Image_01

A group of harvestmen (Prionoistemma sp.) on tree trunk, La Selva, Heredia, Costa Rica.

One of the interesting and commonest species of La Selva is Prionoistemma sp. (family Sclerosomatidae). This species has a small round pink body with black lateral spots and very long legs. Harvestmen usually spend the daytime on the trunk of large trees, at their bases, while during the night time they actively walk up and down the trunk and also over the undergrowth vegetation. When someone approaches them, the creatures begin to shake all over on their thin legs becoming almost invisible for a spectator.

The majority of harvestmen are omnivorous feeding on a variety diets, and seem to be effective predators. On the short video given below it is seen that this Prionoistemma male is feeding on a jumping spider (family Salticidae). The jumping spiders are very active and effective diurnal predators, with sharp colourful vision. Very few predators are capable of capturing them. How on the earth could this harvestman have seized the jumping spider remains a mystery. I’ve never observed this myself earlier.

On the second day of our staying in San Jose (11th June), we had a chance to visit the Pre-Columbian Gold Museum (Museo del Oro) – the archaeological museum organized by the Central Bank of Costa Rica in 1950. This Museum hosts temporary exhibitions on a variety of themes and also houses a remarkable permanent gallery of pre-Columbian gold objects crafted between 300 A.D. and the 16th century, the time of the first contact with Europeans.

Objects manufactured during this period present a mixture of styles generated by contact and exchange with neighbouring regions such as modern central Panama and modern Colombia. Objects exhibited in the Museum were used as trade goods between regions and as ritual ornaments and funerary offerings. Many figures depict men with animal masks, apparently pointing to some superhuman qualities of those leaders who wore them. There are many animal figurines, including those of frogs, which are especially numerous, jaguar, alligators, bat, and others. Of the arthropods, only figurines of butterflies, crustaceans and spiders were displayed.

Butterflies
In traditional stories of the indigenous people of Talamanca, the butterfly is a woman who serves as an intermediary between the natural and supernatural worlds. This role of messenger and special being is reflected in the criteria used to select the woman who can be trained to carry out ritual tasks. They must have positive traits such as honesty, bravery and dedication.

Crustaceans
During the pre-Colombian period the marine environment was intensely exploited for edible species such as shrimps, crabs, lobsters and fish. Figurines of all these animals were manufactured as shown below.

On June 10th, 2014, I visited the National Institute of Biodiversity in San Jose, Costa Rica (INBio, Instituto Nacional de Biodiversidad) and worked with the spider collections. The main aim was sorting out specimens of the jumping spider genus Lyssmanes (Salticidae) for its further taxonomic study. It is a collaborative project with the INBio’s arachnologist Carlos Viquez.

INBio is a private non-profit organization, founded in 1989, that works on the inventory of Costa Rican biodiversity. This institution carries out research on microorganisms, plants, insects and other animals. Since its foundation, INBio has discovered more than 2,700 species new to science. The institution retains large natural history collections numbering 4-5 million specimens and thousands of species. Here are a few photos resulted from my visit to INBio.
