Thread subject: Diptera.info :: Green and yellow flies on sanddunes

I found these two flies on Grey Hair Grass, Corynephorus canescens. Even though one of them i green and the other is yellow I suspect that they belong to the same species or at least the same genus.

Any one who can help me to identify them ?

Thanks,

Meromyza (Chloropidae). The two flies are probably of the same species: the pale green one is a female, the yellowish green one a male.

Idenstification of Meromyza species is difficult. Happily your fly is one of the few which can be identified from photographs with any certainty: M. pratorum, by the following characters:
* yellow palpi
* adbomen with one like and two spots
* frons strongly extended
* sternopleural spot yellow (ventral side, between legs 1&2)

M. pratorum is the largest species of the genus in N. Europe. It is common on dry meadows.

Meromyza of the Chloropidae. You have both female (top two) and male (bottom two) specimens.
