Hi,
This fly from eastern Finland (spruce forest) earlier this year (June 2008). It looks distinctive but I can't put a name to it.
Any help much appreciated
Tristan

I'd say
Trixa caerulescens /
alpina. Chris or Theo will complete this reply.

Trixa "alpina", what I've understood only a colour morph of
caerulescens. These dark ones usually come along in shadier environments and "true"
caerulescens in more open. Then there's also
T. conspersa, which is easy to recognize from the darkened r-m. All quite common around here.

Trixa species tend to be very variable, even at 1 locality.
So I agree with Jaakko

Thanks very much everyone - I shall pass this on.
Are the larval hosts known for this species?
All the best

I don't have any information on the hosts here - Tschorsnig & Herting (1994) says 'hosts unknown' :(
