Hello everyone, I went for a walk today thinking of collecting some insects or spiders on snow and got really lucky. I've found three wingless flies what I think could be Crumomyia pedestris, Lauxaniidae - judging from the images in the gallery. Flies are about 4 mm long, caught on snow in Vilnius, Lithuania, around +0°C. Sorry for the quality of the images - it's hard to make a photo of anything on snow...

Hi Andrius, Did you collect any of these? Good shots by the way, the images show the icy texture well. Edited by Jason G on 15-01-2011 19:09 London's Insects http://londoninve...hostia.com |

Yes, Jason, I collected all the three specimens I've found and they are still walking around in the jar  They will eventually end up in our museum collection, I guess. |

If you can spare one (temporarily) I can confirm ID.

Paul, I have checked the specimens with Krivosheina's 1970 key (Opr.nas.evrop.ch.SSSR) and only Crumomyia pedestris has this kind of male genitalia as I've attached in the photo. Are there any other similar short-wing species to consider? Thank you! Andrius attached the following image:  [108.03Kb] |
