This little fly was on the lid of our compost bin. It is a good place to look for flies because of all the irrestible odors. Length 6.5 mm from the front of the face to the rear of the wings. What family? --Stephen Stephen Cresswell www.americaninsects.net |

Second image. The fly had a clump of pollen (or something) stuck to his front tarsus.

Drosophilidae? |

Yes, perhaps Drosophilidae. Looking at some photos just now I also wondered about Lauxaniidae. The eyes especially look similar.

No, this certainly is Drosophila. In the Nearctis are several species I do not know and abslolutely could not identify from pictures only. It could be a species related to D. virilis but not to obscura and its relatives: There are no 'sex-combs' (comb-like rows of spines) on the fore taris of this male.

Jan, Paul, Thank-you! This one is darker than the other Drosophilids I have seen around here and maybe that should be my excuse for not recognizing the family.  I am glad to know now not only the family but the genus. Sex combs? That sounded intriguing but I went through all my Drosophilid photos and didn't see anything that looked like that. I will be watching for them, though! One more question: Is there any obvious way to distinguish a member of Drosophila from the other genera of Drosophilidae?
