Hi, several of these were sitting on the leaves on July 31. 2008 in Loviisa, Southern Finland. Is the genus id possible ?

Hi Jari, this is a male Thricops, Muscidae.
It's a pity the leg 3 (and 2) are not well in focus, because it looks like T. cunctans, but I can't see if I'm right.

Stephane, T.cunctans hasn't full row of av on f3 (only in apical half and shorter) - 98% it is Thricops innocuus

T. innocuus was my other choice, but I finally rejected this species because mid tibia should have an ad, and t3 should have only 1 strong pd (I can see 2 here).
About av on f3, I read on gregor et. al. that T. cunctans does have a complete row of av.
That's also why I did want to see if the spur is present on t3. ;)

Really, Gregor write that f3 with full row of av on f3. May be, but in this case these av only very short in basal 2/3.
T2 ad may be invisible, t3 spur has to be very clearly visible even out of focus, but enterly invisible in our case.
So, I'm still 98, ok 95% sure in T.innocuus

Hi, thank You so much for Your attention. Here is one more picture of T2 and T3.

I would certainly not be considered as a pig-headed boy , but the two strong pd on t3 are a key character to rule out T. innocuus. :@
Maybe a little stubborn even so...:D

Hi, maybe it's cunctans anyway. T.innocuus has been found these days only from northerns parts of Finland and cunctans seems to fly in whole country.
