Fieldwork in Shropshire

Posted by Erica McAlister Oct 16, 2009

Ok, so before my main post I just want to add a little side note that if anyone missed the new 'David' documentary (I was on fieldwork), that after about 24 minutes in there is the most fantastic piece of film showing stalk-eyed flies inflating their stalks. Brilliant...love the flies

 

But back to fieldwork. With a car packed with microscopes, field guides, pinning equipment and exciting new camera lens we (Kim and I) set off for Bridgnorth, Shropshire. And what a lovely place it was! We arrived early and as the others were not due till 7.30 we went for a walk to and around the town. I have a new macro lens for my camera to enable me to take loads of insect pictures but I need a little more practice; it does not help when the insect is moving, the leaf that it is on is moving and me too! We collected comments from the passers by, with one even saying I reminded him of his son....It is a lovely town though, on two levels connected by the oldest and steepest inland funicular railway - one whole pound for a return journey!

 

We met Roger Morris, who organises the fieldmeetings of the Dipterists forum back in the B&B and then the rest of the motley crew back in town. Found a restaurant that made the best pies . Food and nutty ale are very important components of fieldwork. The others were Alan 'Mr Whippy' Stubbs, Peter 'Gnatman' Chandler, Chris 'Spiderman' Spiling.  (A photo below of gnat man in action!). We were joined during the course of the trip by Hannah 'happily married' Cornish and Malcom 'extender net' Smart - a Robber fly expertpeter bum.jpg

I think that just after this photo was taken was my first field injury of the trip. I too had my head in a net sucking up flies into my pooter when I realised that I had not just swept up flies but also a wasp...and she was a bit angry. I was stung three times (I still have the lumps) on my head and she got stuck in my hair! But I calmly took my hair out of its ponytail and tried to ensure that she had finally got away. I asked Alan to check as he was the closest. Upon telling him that I was attacked and that I needed him to check for the wasp his reaction was - 'it's gone' and then he walked off!! I could have been dying!! I fell down a whole that resulted in one leg and foot become oxidised .

 

The practice of the meetings is to conviene at one of the B&Bs that we are staying at, check the maps, and then head off in convoy for some net action. We travelled around three counties hunting for flies on this trip and I have to say that I was very impressed. The mornings were cold and so we got to relax and try and identify material from the previous days - the flies would not be out in the cold . We averaged three sites a day. We were specifically trying to find fungus gnats, craneflies and platypezids. I did not get any of the latter . Afterwards we would go back and pin for a couple of hours before dinner and then for a few more after dinner. We came home with a lot of material that we can add to the synoptic collection for the AMC (Angela Marmont Centre). There were relatively few gnats though as there was very little fungi. The area has not had much rain at all and everywhere was very dry. We were hoping for over a hundred but not sure that we got 50 (species not individuals). But as the fauna was so deporporate we actually managed to identify a fair chunk of the material and we have got many different hoverflies, gnats, craneflies, muscids etc etc.

Here's one of the pretty hoverflies.

 

We were also shown the larval habitats of hoverflies with Roger carrying out some excavation work on plant roots (they were all put back afterwards...well apart from one....but enough said).

All in all, very successful. It was good to get back into the field and see different parts of the UK. I need to work on my macrophotography but sitting in front of me at work are boxes of material that will keep me going for a while!

So I am in the new Darwin Centre and unpacked. And I have to say it is lovely. I have my specimens that I am working on in a cabinet directly behind me. I have a spacious desk with all my catalogues arranged close by. I have a wet lab for sorting my specimens in alcohol a minute away. And it is so light that desk lamps are redundant. And I have a foot rest. I can finally get back to work (there is still the minor problem of the collection that is yet to move into the building though….early November for that and my, it will be crazy). And I have to find a quick route from my desk to the staff entrance..

Yesterday, though, I got to work on some recuration. I had lent (and by that I mean the Museum) all of our Sisyrnodytes specimens to a researcher in South Africa. These are a genus of Robber flies and the researcher in question is a leading authority. The specimens returned some while ago but I have not been able to put them back in the collection as he had designated one a Lectotype and described two new species from the material.

 

When new species are discovered and named, if it comes from a series then the author may choose to call all of the specimens from the same collecting event etc ‘Syntypes’ (we often have 10+ syntypes). This is not very helpful when it comes to descriptions, so what often happens is that one of them at a later point will be designated a Lectotype. To have this accepted along with the new species that he described, he needed to publish his descriptions.

 

This has now happened so I am able to link the material to the publication, update our system and reinstate the material (all lovingly housed in new Museum standard trays) back into the collection. I have now only another couple of thousand drawers to recurate and a whole lot more of unidentified material…..

And my nice new ones

 

We are off on fieldwork tomorrow. We have five days based in BridgNorth, near Wolverhampton….Not familiar at all with the area so it should be interesting. It is with the Dipterists Forum and I think that there will be about 10 of us.Today and yesterday the three of us from the Museum that are going have been organising our equipment. We have nets, microscopes, wellies, id guides etc etc that are waiting to be loaded up.

 

These trips are brilliant for many reasons. We get to run round the countryside, we learn a lot more about the British Fauna and we get to socialise with some of the top Dipterists in the UK. We are prioritising at the moment for species that we don’t have in our collection. It does seem odd that there are some UK species missing from the national collection but it has not been a collection priority for a while.

 

This is all changing with the opening of the Angela Marmont Centre for UK biodiversity. With over 7000 species of fly in the UK we should be kept busy hunting for a while

Leaving home

Posted by Erica McAlister Oct 1, 2009

When I first started at the museum I was based in the old Entomology building, full of old cabinets, rooms stuffed full of specimens and hidden corners.

moving desks (8).JPG I was only volunteering or on contract work and so my first 'real' home was in the Origins Gallery, half way along on the bounciest part of the floor (we are on a mezzanine which bounces quite violently at times). So it is with some sadness that I have now nearly packed it all up and am ready for our move to the Darwin Centre on Tuesday.

 

The amount of dust is ridiculous! All the little presents that I have been given over the last couple of years have now been boxed up and all books, microscopes etc are ready for the movers!moving desks (9).JPG

 

I have spent the day filing correspondence and incorporating loan material that has been returned, back into the collection. It is good to have a sort out now and again other wise I will end up retiring and there being boxes of material everywhere....
