Sorry technical glitch - the full text should read:
In June this year Rob Wolton spent part of his holiday recording Diptera in the Uists. I've not seen his list yet, but he netted a Neoascia hoverfly which keys out on all characters to Neoascia tenur, apart from the yellow marking on the hind femora. You can see the photographs at http://www.dipteristsforum.org.uk/t3165-Neoascia.html.
Rob has asked anyone who catches a Neoascia hoverfly to check the characteristics carefully (particularly basal ventral expansion to the hind femur) and to send their observations to OHBR. I will also accept specimens if anyone finds another of these atypical Neoascia. Rob's Neoascia was netted at North Loch Eynort "somewhere along the loch side path between the car park and, crossing the first deer fence, the stream exiting from Loch nam Faoileann. Possibly on some low Salix bushes close to the path, on the other side of the deer fence from the established woodland, it could have been from one of the wet flushes there - NF79682867.

Neoascia are small black hoverflies (3.5-5mm long) with narrow wasp like waists, especially the females. Associated with wet places and often found on low growing flowers such as tormentil and creeping buttercup.

So the next time we have a sunny day, have a careful look at the small black "flies" on the buttercups and see if you can find some Neoascia.
