Fleas are some of the oddest insects and sit in a strange position when it comes to how the public feel about them. Fleas are hated for their feeding activities and disease transmission whilst their aesthetics have long been admired thanks to mostly the works of Robert Hooke and his diagrams in Micrographia.

Hooke writes ‘the strength and beauty of this small creature, had it no other relation at all to man, would deserve a description’. Wonderfully phrased, this sentence sums up the feelings I have when looking at these small creatures.
Natural history collections provide an enormous evidence base for scientific research on the natural world. We are working to digitise our collection and provide global, open access to this data via our Data Portal.

To digitise the collection we are developing digital capture flows that cater for a wide range of collection types. One of the applications we have developed is Inselect – a cross-platform, open source desktop PC application that automates the cropping of individual images of specimens from whole-drawer scans.
We are in the process of digitising the Museum’s parasitic louse (Phthiraptera) collection, which consists of around 73,000 microscope slides. The collection is one of the largest – and the most taxonomically comprehensive – in the world.
Human lice specimens (Pediculus humanus capitis)
Lice are permanent ectoparasites, meaning they live on the outside of their bird and mammal hosts. They are highly host specific, with the majority of the ~5,000 louse species being unique to a particular host species of mammals and birds.
Our previous blog post looked at preparing the Lepidoptera for digitisation. In this post, we will look at the second part of the digitisation process; the imaging and transcription that allows data to be set free and accessed by the global science audience on the Museum’s Data Portal.

Let’s find out what’s involved and why it’s leading to new ways of accessing and using the information in our collections. Continue reading →
It has been several months since my last post looking at blue whale on the move but finally the long process of cleaning and conserving each individual bone has been successfully completed and the conservators are now just embarking on surface scanning the bones in high definition. Conservation can be an extremely slow process but it is worth the time and effort. During the past 9 months the team have cleaned and conserved over 220 individual bones. This equates to over 110m2 of whale bone surface area.

During this time we also planned the final position and articulation of the whale for its suspension in Hintze Hall so the armature design could commence. This post outlines the conservation treatment and articulation planning phase of this project.
We are working to digitise more than half a million British and Irish butterflies and moths. Our three year iCollections project started in 2013, and we have received additional funding from the Cockayne Trust to continue this digitisation work to September 2017.

The mass digitisation of this collection has given Museum scientists the opportunity to study these specimens in new ways. In addition to research carried out in the Museum, digitisation also allows anyone around the world to see the specimens via the Data Portal. Continue reading →
Before the Museum exhibition about Colour and Vision closes on 6 November, I thought I should write a piece about some of nature’s most amazing eyes (their patterns and shapes). I’m talking of course about those belonging to flies – the most enigmatic of all species on the planet – and specifically all the species referred to as stalk-eyed flies.
In November, Laura Newsome, a Research Associate, and Sul Mulroy, a PhD student at the University of Manchester Geomicrobiology group, travelled to California for beamtime at the Advanced Light Source synchrotron at the Lawrence Berkeley National Laboratory.

Laura and Sul travelled to analyse samples generated from their work on the COG3 project. Sul reports from the visit.
