A Fashion Flea-esta


By Danielle Czerkaszyn, Librarian and Archivist


In September 2021, the Museum initiated its first “Specimen Showdown” on Twitter and Instagram, where followers could vote on their favourite specimens from our collections. Over the course of the month, followers narrowed down their favourite among 32 specimens from four collections: The Library Legends, The Bygone Beasts, The Rock Stars, and The Birds and The Beetles. The final showdown was between the Connemara Column (found in the Main Court of the Museum) and the Pulgas Vestidas from the Library and Archives. In a nail-biting race, the Pulgas Vestidas narrowly beat the column with 53.9% of the vote.

But what are Pulgas Vestidas? And why are they so popular?

Dressed fleas, you say?

The delicate art of dressing fleas in tiny costumes, known as ‘Pulgas Vestidas’ in Spanish, flourished in Mexico for over two centuries. It is believed that the craft began in Mexican convents where nuns would fashion tiny pieces of clothing onto dead fleas. An important point to note is that the fleas themselves were not actually dressed — instead, they formed the heads of the figures. The individual fleas were set in matchboxes and decorated with elaborate human costumes, hats, shoes, and accessories. Sometimes the fleas were set in whole scenes, often as married couples in miniature dioramas of everyday life. The bride and groom sets were the most popular, with the bride sporting a long veil and the groom in his best suit. The nuns would then sell the fleas for a small amount of money to passing tourists. The trade was later picked up by the local villagers and Pulgas Vestidas were widely sold to tourists visiting Mexico in the early twentieth century.

Dressed fleas were popular with tourists until the 1930s when the art declined in popularity. An increasing awareness of hygiene meant that fleas were rapidly regarded as unhealthy. Many dressed fleas were consigned to the bin, and Pulgas Vestidas became a lost art as tourists’ tastes for memorabilia changed. Examples of these tiny curiosities are now rare collectors’ items.

Pulgas Vestidas at Oxford University Museum of Natural History

The Museum’s dressed fleas were collected in 1911 by American archaeologist and anthropologist Zeila M. M. Nuttall who specialised in Mexican history and culture. She sent the dressed fleas to her brother, bacteriologist George H.F. Nuttall. George formally donated a collection of 50 Ixodidae (ticks) to the Museum, and it is likely he also gifted the dressed fleas at the same time. The dressed fleas would have been considered more of a Victorian novelty, and so were not formally recorded or accessioned into our collections.

Although most of OUMNH’s dressed fleas reside behind-the-scenes, one example is on public display in the Upper Gallery of the Main Court. Sporting tiny clothes and a backpack, the flea is just visible with the help of a magnifying glass. Clearly, this one was born to flea wild.

OUMNH’s Pulgas Vestidas are definitely among the more unusual items in the Museum’s collections, and they were clearly head and shoulders above other specimens in the September Specimen Showdown competition, despite being no more than 5mm tall! Pulgas Vestidas may be small, but they certainly are mighty.

I’ll Flea There

The dressed fleas will be on display, with a flea-tastic craft, for the Museum’s free evening event ‘Late Night: A Buzz in the Air‘ on 27 May from 7-10pm.

Community science: what’s the value?

ONE SCIENTIST OFFERS HER PERSPECTIVE


By Sotiria Boutsi, Intern

I am PhD student at Harper Adams University with MSc in Conservation Biology, currently doing a professional internship at the Museum of Natural History in the Public Engagement office. My PhD uses genomic data to study speciation in figs and fig wasps.


For most of our history, humans have been observational creatures. Studying the natural world has been an essential tool for survival, a form of entertainment, and has provided the backbone for various legends and myths. Yet modern humans are rapidly losing practice when it comes to environmental observation. As more and more of us relocate to busy urban environments, we find ourselves with little to no time to spend outdoors. Knowledge of the natural world is rapidly becoming the purview of professionals — but it doesn’t have to be this way…

Community science is a term that describes scientific research activities conducted by amateurs, often involving observation or simple computational tasks. Many citizen science projects target schools or families, but everyone is a welcome participant. The purpose of such projects, which run all around the world, is to encourage non-professionals to get involved in science in a fun, voluntary manner, while also collecting data that are valuable for scientific research.

One of the most common forms of community science is biodiversity monitoring. Biodiversity monitoring projects invite people with various levels of expertise to record observations of different species in their local area, and upload evidence like photographs and sound recordings to a user-friendly database. In doing so, they also provide important monitoring data to scientists, like information about the date and location of wildlife sightings.

The Asian Ladybeetle (Harmonia axyridis) was first spotted in the UK in 2004 and since then it has become very common. It is considered one of the most widespread invasive species in the world, with introductions throughout Europe, North and South America, as well as South Africa. Reported observations through the UK Ladybird Survey (Enter ladybird records | iRecord) can help us monitor the spread of this insect and see how other, native species respond to its presence.

There are a variety of mobile apps and online platforms for reporting observations, with some specialising in particular groups of organisms like plants or birds. From the raw data that is uploaded to these platforms, species can be identified through a range of different methods:

  1. Automatic identification from uploaded evidence – often using techniques like image/sound analysis or machine learning
  2. Community feedback – multiple users can view uploaded evidence and make suggestions about which species have been recorded
  3. Direct use of users’ own suggestions – for users who are more experienced with species identification

But are these data actually used by scientists? Although individual contributions to community science projects may seem to be of minor importance, when considered collectively they act as extremely valuable records. Having distribution data for species can help us understand their habitat preferences, and also enable us to monitor invasive organisms. Moreover, long-term data can inform us about species’ responses to changes in their environments, whether that is habitat alteration or climate change. Science is driven by the accumulation of data, and citizen science projects can provide just that.

Biodiversity monitoring through citizen science projects encourage us to notice the tiny beings around us, like this beautifully coloured shiny Green Dock Beetle (Gastrophysa viridula). Moreover, recording common species like the European Honeybee (Apis mellifera) over different years can reveal temporal patterns, like early arrival of spring.

In addition to the benefits to the scientific field, community science projects can also be of huge value to their participants. Firstly, engaging in such activities can help us re-establish our relationship with the wildlife in our immediate environment — we might finally learn to identify common species in our local area, or discover new species that we never realised were so close by. It is surprising how many species we can even find in our own gardens! Moreover, community science events, like biodiversity-monitoring “BioBlitzes”, encourage people from different backgrounds to work together, strengthening local communities and encouraging environmental protection.

Oxford University is currently running the community science project “Oxford Plan Bee“, focusing on solitary bees. The project is creating a network of bee hotels: small boxes with branches and wooden cavities where harmless, solitary bees can rest. The hotels are spread throughout the city, and locals are invited to observe the bee hotels, take photos, and send in their findings.

Overall, community science is as much about being an active participant in the community as it is about doing science. These projects are a celebration of both collective contributions and individual growth. More than anything, they are a chance to pause and notice the little things that keep our planet running.

Reindeer are not just for Christmas

WHAT WE CAN LEARN FROM BRITAIN’S ICE AGE RANGIFER


By Emily Wiesendanger, Volunteer


If you’ve ever visited the Skeleton Parade in the Main Court of the Museum, you may have noticed that nestled between the Malayan tapir and the rhinoceros is the skeleton of a reindeer, or caribou if you are from North America.

Today, reindeer are found throughout the Arctic and Subarctic in places like Canada, Alaska, Russia, and Lapland (Norway, Sweden, and Finland). However, their range was not always so limited. During the Late Pleistocene – around 126,000 to 11,700 years ago – it would not have been unusual to see herds of reindeer roaming freely across most of Britain and western Europe. In fact, reindeer sub-fossils in the form of bones, teeth, and antlers have been found at a number of Oxfordshire sites including the excavations at Cassington and Sutton Courtenay, which are kept behind the scenes in the Museum’s extensive Paleontological Collections.

Studying these Ice Age reindeer can teach us as much about the future as they can about the past. Pleistocene reindeer were likely similar to their modern counterparts, which undertake large, bi-annual migrations between summer and winter grazing pastures. Looking at the movements of Ice Age populations of reindeer can therefore help us to understand how modern reindeer may respond to climactic and environmental changes in the future. This is possible because reindeer only come together in large herds at certain times of the year. During these seasonal aggregations, the herd is characterised by different combinations of ages and sexes. Therefore, by looking at the age and sex of the remains of reindeer present at a site, we can tell the time of year that they were left there — in particular, we can infer the sex of reindeer from their bones, their age from their teeth, and their age and sex from their antlers.

Modern reindeer are highly adapted to cold environments (-45 to +15°C) with two layers of fur (the tips of which turn white in the winter), short and furry ears and tails, and large feet to make walking on snow and digging for food much easier. Reindeer even make a clicking noise with their feet, produced by a tendon slipping over a bone, to help keep track of each other in blizzards or fog.

Unfortunately, it is extremely rare to find anything so complete as the reindeer in the skeleton parade. Instead, you are much more likely to find remains like the antler below, which was excavated from Sutton Courtenay. Despite being only a fragment, it is exactly this kind of sub-fossil that can help us to understand more about the movements of reindeer during the Late Pleistocene.

This left antler base and skull from a male reindeer found at Sutton Courtenay can be used to determine which season reindeer were present at the site.

Reindeer grow and shed a new pair of antlers every year, and this happens at different times of the year for males and females. If you can identify whether an antler is male or female, shed or unshed, you can also tell the season of death. The Sutton Courtenay antler featured above would have belonged to a male reindeer. At its base, we can see it is still clearly attached to some skull bone, and so is unshed. Because males only have their fully grown antlers between September and November, this particular reindeer must have been in the area around Sutton Courtenay during the autumn. It is by using similar deductions that we can also tell that Rudolph and his antlered friends would have actually all been females — by the 24th December, males have already shed their antlers, but females will keep them until the spring!

After studying thousands of these kinds of remains from all over Britain, we can start to build a picture of where reindeer were at different times of the year. It’s amazing to think that we can learn so much from simple skeletons. So, the next time you visit the skeleton parade, take a moment to think about the secrets they may be hiding.

Open Doors

OXFORD UNIVERSITY MUSEUMS AT THE INTERFACE OF ‘TOWN’ AND ‘GOWN’


By Rawz, Sound Artist in Residence for 2022, St John’s College, Oxford


Oxford is a curious place and, for me, it’s getting curiouser and curiouser. 

I love this city; I’ve called it my home for more than three decades. I couldn’t picture myself living anywhere else. But recently, I realised I’d only ever really seen half of my fair city, that there was a world beneath the dreaming spires that I had never even considered that I would be permitted to explore. I realised that I had never really walked through Oxford city centre; I had always been guided around it by 10 foot high fortifications and locked doors.

I grew up very much on the town side of Oxford’s notorious ‘town versus gown’ divide. I left school with no qualifications, and since then have spent much of my working life supporting the most marginalised people in the city, particularly young people struggling with formal education as I did. Doing this in a city whose very name is a buzzword for elitism and privilege means that I’m no stranger to juxtaposition. It continues to influence my art to this day.

I’m a hip hop artist, primarily focused on lyric writing and poetry. In 2009 I set up my own business, the Urban Music Foundation, with the hope that I could pass on some of the art skills that helped me get through tough times growing up, and that have enabled me to express myself fluently as an adult, and build a career around my art. I’ve found music and lyrics to be a uniquely useful tool in communicating ideas that are hard to transmit in any other way. Someone once said to me that music is what emotions sound like, and I’ve found that to be true.

After a video call with one of GLAM’s community engagement team during the lockdowns of 2020, I had an idea for a project that became Digging Crates — a decolonisation project using hip hop music to reinterpret the musical instrument collection at the Pitt Rivers Museum, next door to the Museum of Natural History. I immediately saw the project’s value as a way to analyse and address some of the divisions and imbalances I see in Oxford, and in wider society. Just over a year after I sat down and wrote the original proposal for this project, I was offered the position of Resident Sound Artist for 2022 at St John’s College. Even as I write this I feel a surreal mix of pride and disbelief — not many people from my community in Blackbird Leys would have considered the idea of being offered such a post in their wildest dreams!

The front doors of the Museum are open every day from 10:00 to 17:00.

The past 18 months have seen doors open – both literally and figuratively – that I had never even considered walking through. I hope they continue to do so, and that they remain at least a little ajar for those following my path. Many of you, dear readers, will be glad to know that one place I have enjoyed exploring, both as a “townie” and, more recently, in my newer self-proclaimed title as “Town Ambassador to the Land of Gown”, is the Museum of Natural History. Of all Oxford’s museums, the Museum of Natural History has the biggest impact as soon as you walk through the doors (which are usually wide open). I’ve taken many “disengaged” and “hard to reach” young people to visit, and the heady cocktail of stuffed animals, dino bones, and cool rocks almost always proves irresistible to all but the most sceptical children, young and old. I would love an opportunity to get creative in this amazing space and am often trying to think of an excuse. Any ideas – you know where to find me! 

Whatever happens next, stepping through the looking glass into this strange new world of the gown with its quirky, bizarre traditions, and its fascinating, inspiring, and problematic histories, is an experience I will never forget. I’m honoured to be the person taking this step on behalf of my community, and grateful for all those who worked hard and made sacrifices for me to be able to do so.

Bee-flies: A sign of Spring

At this time of year, after the long winter months, we are all looking for signs of Spring.   One thing that entomologists look forward to is the first sightings of bee-flies.   These very cute, furry flies start to emerge in late February and early March.

Bombylius major, the dark-edged bee-fly, is one of Erica McAlister’s favourite British insects and she tells us why in this video.

Find out more about Bee-flies

To find out more about bee-flies, check out this page on the Dipterists Forum. There is also an excellent guide to bee-fly identification which you can find here.

In addition, the Dipterists Forum run an annual Bee-fly Watch which gathers together records of sightings.  This is really important for monitoring changes in distribution and flight period.  You can contribute to this important science project by adding your sightings here:
