The ‘spatial wealth’ of the Museum’s collections is often ignored or at best under-appreciated. Most specimens if not all have a spatial locality associated with them, either written on to a label, written in a notebook, or on the specimen.
These localities can vary between very precise (e.g. a GPS-based latitude/longitude), very imprecise (e.g. ‘South America’) or, most likely, somewhere in-between. Most specimens within the Museum do not have a latitude and longitude, but do have detailed locality information on the accompanying label, which can be used to define co-ordinates for that specimen. So what is georeferencing, why do we need it, and how do we use it?
Well as 2015 becomes an ever distant memory and we scuttle, creep, scurry, amble and roll (for this is how beetles move right?) into 2016, let us look back on a very successful year of collection enhancement.
The collection here is a big one, and serves to represent the world’s known Coleoptera biodiversity as comprehensively as possible but it is an uphill task to curate, much in the same way as a dung beetle may struggle against the desert sands with its dung ball prize.
Within the Diptera section we are asked a lot about individual species of flies and so we thought we would put pen to paper (or key to board) and give some species descriptions of the more popular requests.
The stunning 25 metre long skeleton of a blue whale (Balaenoptera musculus) currently suspended in the Museum’s Mammals and blue whale gallery since 1934 is to be taken down in January 2016. After an extensive period of cleaning and conservation it will then be re-suspended from the ceiling of the Hintze Hall in the summer of 2017.
Following months of careful consideration the blue whale skeleton has been chosen to take centre stage at the Museum, to give an immediate introduction that illustrates our research into the rich biodiversity of life on Earth and a sustainable future, as well as the origins and evolution of that life.
Moving a blue whale around is quite literally an enormous project which involves many specialists including curators, project managers, scaffolders, structural engineers, specimen handlers, and mount makers, to name but a few. Central to this project are the conservators who will be ensuring the skeleton is given the due care and attention it needs.
So exactly how do you work on a large specimen suspended over 6 metres above the ground with many other specimens and models surrounding it? That’s the story we aim to tell in our upcoming posts in our new Conservators blog.
One of the most important aspects of being a curator is not actually related to the Museum’s collections, but instead it’s ensuring that we encourage others to become interested in the natural world and the role we perform. So, this August gone, I was very lucky to have help from Billy Stockwell, a young wildlife enthusiast, who spent a few days at the Museum for work experience. Here’s his own tale of his time here, which he has kindly given me permission to reblog and I encourage you to read the rest of Billy’s adventures in the world of nature on his own blog:
The Natural History Museum is far more than just a museum. With 80 million specimens straddling 4 billion years of natural history it’s more of a microcosm of mother nature herself; a snippet from each stage of our planet’s life hitherto. Its collections are no less over-whelming, including prehistoric creatures worthy enough to feature in Spielberg’s Jurassic Park, to millions of butterfly specimens whose species inhabit our modern world today.
From a visitor’s perspective the most exciting aspects of the Museum may be the captivating dinosaur exhibition, the butterfly house, or even the Museum’s gift shop. But if you’re brave enough to venture behind the scenes you have another thing coming! And that’s exactly what I decided to do for my work experience a few weeks ago…
On 25 June the Museum will open its doors to a special event in celebration of the international and global commitment between countries, industry, charities and academia to work together against Neglected Tropical Diseases (NTDs). This commitment was first agreed upon in London in 2012 and has since been termed the London Declaration On NTDs.
By joining forces to fight NTDs the world would achieve a huge reduction in health inequality paving the way to sustainable improvements in health and development especially amongst the worlds poor. The 25 June sees the launch of the third progress report, ‘Country Leadership and Collaboration on Neglected Tropical Diseases’. A pragmatic overview of what has been done, what has worked, what hasn’t and what key areas still need to be achieved.
Weevil researcher Dr Chris Lyal elucidates on the darker side of weevil life-histories and they are not as friendly as you may have imagined…
Weevils are perhaps the most inoffensive of beetles – well, unless you’re a farmer, forester or horticulturalist, in which case you may take a rather dimmer view of them, since some species of this huge group are major plant pests. However, to focus on the animals themselves and ignore inconvenient economics, they seem to look out at the world through immense soulful eyes, and trundle rather erratically along like one of those clockwork plastic children’s toys with slightly more legs than are truly manageable.
As herbivores, they spend their lives up to their antennae in plants, nibbling at leaves and flowers, buds and roots. They may have a long projecting rostrum at the front of their heads, but they do not behave like horse-flies, bed-bugs or any of the rest of the blood-sucking brigade and try and force it through your skin and suck out your life-juices. Adult weevils are covered in scales and sometimes very brightly coloured, but they have a previous existence as a larva, chomping their vegetarian way inside fruit, stems, leaves or roots. Larvae are fat, white, legless comma-shaped beasts, almost blind and apparently interested only in food.
Again, not one of nature’s bad boys (unless, as I said, you are concerned with keeping plants alive, in which case I may be irritating you by now). However, not all is as it seems. Some weevils, it turns out, have a darker side to their nature. Some are killers. Some are cannibals.
I’ve just recurated an entire family of flies – and in only three days! It’s not often I can do that (I have been recurating the world bee-fly collection for over three years now and it’s still ongoing), but then there were only 14 species of this family in the Museum collection. That doesn’t sound like a lot, but after all the shuffling around over the last 40 years with the taxonomy there are only 20 described species within 2 genera.
So in terms of species numbers, it’s a very small family… but in terms of individuals, they are far from small. The family I am talking about are Pantophthalmidae, and they are some of the largest flies on the planet (although I think that Mydidae can rival them). There is no real common name; they are more often than not shortened to Pantophthalmid flies, but are sometimes referred to as timber flies or giant woodflies.
And for such large creatures we know very little about them.
The date in the title of this post marks the sad passing of one of the Museum’s tiniest volunteers: in early February I discovered Beetah, my Carabus violaceous, lying still on her coconut substrate and to be honest, a little dried out.
OK, I have decided to create #WorldRobberFlyDay. All the time now, we hear that this large mammal or that large mammal has a ‘day’, and that got me thinking. Buglife have an Invertebrate of the Month, but even they are not very often the lesser-known insects, including the flies.
And I wanted global. Let the world celebrate! Why is it always the large stuff or the pretty (and, in my opinion, slightly less important) species? So I thought about it and decided it was about time that we championed more aggressively the rights of the small and endangered flies. These creatures are some of the most charismatic animals on the planet. The robberflies, or Asilidae, are truly worth celebrating for their looks, for their behaviour, for their good deeds to us, and because many of them are threatened.
The UK boasts 28 species of Asilidae (OK, so that’s not a lot in terms of flies, but hold on – we have only 30 native terrestrial mammals, of which 17 are bats and 2 are native marine mammals). Globally there are more than 7,500 species, and as such, it is one of the largest families of insects today. In fact Torsten Dikow, a world expert on this group, has them as the third most speciose group of diptera. This is a group, therefore, that has a large impact on the environment in which they live.
