Moscow, park, 29 apr, 5-5,5mm. Two flies in one place, both collected, but I don't know is it of same species or different. Looks similar to my unexpirienced eye, but surely first shining, second - not (doesn't matter of light conditions)

Two different species: first one Lypha dubia (?) and the second one I am less sure about but it's definitely a tachinid - possibly Triarthria setipennis (?)

Thank you Chris.
Soon I'll try to go through Tachinidae key for genera

P.S. Where is your comments for new Gonia? At least you have now to admit that Russia is best place for Gonia hunting

---

Now I think the second one isn't Triarthria because Triarthria shouldn't have hairy eyes ... but not sure which species it can be

Hi Nikita,

Both are Lypha dubia, first a male, then a female
Difficult to say why, the curvature of the apical vein and the bronze colouration of the abdomen are typical.
Common spring species.

Thank you Theo.
On one hand only one species worse than two.
On other hand better. I spend half an hour counting all setas trying to find any difference. Everything was similar...

This small (4-5mm) Tachinidae from wall of my countryhouse in Moscow region. I collected several flies (25 & 30 apr). All of them distictly less than 3 Lypha dubia (all collected inside Moscow, in park). I have now. All with more shiny body and some irridiscent wing, basal part of R4+5 - black, not yellow. All other - almost similar. Looks like another species of same genus. In my key - only L. dubia, but in European check lists there is also Lypha
ruficauda. Or it is inside individual variability of L. dubia?
