I am sure I've seen this one on here before but I can't find it...It was found this evening at Scatsta Airport sitting on bags of Salt/Grit. Size was 3-4mm. EDIT; Added Family and Genus to heading.

Thanks Andrzej and Tony I thought it looked a bit like an Ephydrid with a froglike face... I have one entry for Parydra in my List for Shetland; Parydra pusilla Mg./nigritarsus Strobl Whatever it is, it's the first time I've seen it up here , nice to find a new fly.Regards Roger EDIT; Another photo just to use it up Roger Thomason attached the following image:  [98.24Kb] Edited by Roger Thomason on 10-04-2010 00:43 |

Hi Roger - it's not pusilla or nigritarsis. There doesn't appear to be a large bristle on the outer surface of the mid coxa, and there looks to be a small appendix on R2+3, so I suspect this is corarctata (female).

Cheers Tony It would be great to get this little fly to species. Here is a dorsal view which I have done a repair job to in Photoshop....exposure was all over the place, but it has come out OK  .Hope this helps in confirming your suspicions. Roger Thomason attached the following image:  [65.17Kb] |

Yes, looks like coarctata OK - if you can just check the mid-coxa - coarctata lacks the strong bristle which is present in the other species.

Thanks Tony I have just zoomed in on all 48 Photo's I took of this fly....  , what a crap way to spend a Sunday Night.. ...Anyway, I can't find a bristle, other than these few hairs hanging down on the mid-coxa. Don't know if this is what you are looking for.

No, they're not big enough. I'd put it down as coarctata.
