Hi Nikita,

You can name this Geomyza tripunctata (a male). More to the south this species is often more reddish (orange if you like). It seems to be a wellknown phenomenon in all kind of species that in warmer climates species become more reddish. Or did you collect this specimen on a higher altitude (i.e. colder climate)?

It seems that this rule doesn't work this time. All specimens not only fron sea level, but from very sea shore (50m or less)!

Hi Nikita,

Well, I would not exactly call it a rule, but the percentage of reddish specimens of G. tripunctata is much higher in the south then in the north.
By the way, a very nice photo again!
