Hi!

This was inside on 5th September 2010, near Lincoln UK.

Size ~3mm. I wondered if anyone had a clue of what it is due to the colour!

1 pic + 1 crop

Yes Sara, it is exceptionally nice! Grin

I have been searching on Bug-guide, John Carr has mentioned that:

Gall midges with five tarsal segments, first longer than second are Lestremiinae.


I think the first tarsal segment is longer than the second, and it has 5 segments!

A big HMMMMM! I'm not sure I can see them now! I thought I saw a joint where I have put a funny ? next to the line, but its not obvious and I can't see it on the first tarsus. Frown I lightened it a little to see better..

I think I can see it on the first leg Sara! I have edited the pic a little to brighten it, and sharpened more. Where I have put the two black lines I think there is a dark line which looks like a joint, but there also looks to be a small notch just below where I have put the thin black line. awkward

The original looks a little better than the uploaded pic, I think!

The "?" does not point to a segment division. The division between first and second segment is very faint. It is about twice the diameter of the tarsus from its base.

If I got that right John, I have put a tick next to the black line where I think the division is.. so this does mean there are 5 segments?

That's about where I see the division. The segments are fused together and the exact location of the joint may not be clear.

So we are looking at a gall midge with a very short 1st and comparitively long 2nd tarsal segment.

I'm relying on your knowledge John! Does this indicate a subfamily?

I think it only excludes Lestremiinae.

In Lestremiinae the first segment is not extremely shortened, in other cecidomyiids the second is much longer than the first.

Lestremiinae also has ocelli present, which your specimen does not seem to have.

Thank you all for the extra information!

I have checked the wing venation on drawwing, there are subfamilies given. The one which mine looks to match suggests subfamily Cecidomyiidae within the family Cecidomyiidae. Is there such a subfamily? It's not listed for here!

http://www.drawwi...idomyiidae

We only have three subfamilies listed..

http://www.dipter...hp?id=2731

I altered the pic of the wings so the venation can be seen better..
