My guess would be P. pusilla - can you see the halteres or face on any other photos?

Thanks a lot for your reply, Chris!! I am afraid these are the only photos of this specimen But I have much better pictures of another specimen feeding on the same flowers just a few minutes earlier. Only that the other one looks somehow different. The distance between the eyes looks a bit wider. Perhaps the female? No idea if both sexes can be told apart from external caracters in Phasia. I am going to prepare pictures of the other specimen in a different thread as soon as I can But halteres are nearly impossible to photograph in Phasia They are always covered by those huge calypters What should I look for in the face of the other specimen? That will help me to select the most useful views |

Possibly female - Phasia pusilla & barbifrons are not easy to sex.

Pusilla or another species from the pusilla-group (Hyalomyia): there are many more in Spain ! Impossible to tell from pictures (genitalia needed). Theo |

Chris, Theo, thanks for your replies I see there isn't much point in struggling with pictures of this group. Phasia (Hyalomyia) sp. is good enough for me |
