Trying to figure out the family of these two tiny flies. Fly #1: Size was 1.9 mm. Resting on a squash leaf, open area near woodlands, West Virginia USA, 10 August 2006. Fly #2: Size was 3.2 mm. On Queen Anne's Lace, open area near a large pond, West Virginia USA, 27 August 2006. Stephen attached the following image:  [45.49Kb] --Stephen Stephen Cresswell www.americaninsects.net |

Hi Stephen. 1. Hydrellia sp., Ephidridae 2. I think some Chloropidae Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Thanks for your help Nikita! On Fly #1, he was not anywhere close to water, but I realize flies sometimes end up in unusual locations from wind or some other cause. He may have been out looking for a new location. Anyhow I appreciate your help with these two little guys!

I agree with Nikita that fly number 1 is Hydrellia, though the wing venation appears to be unlike any European species. However I think this could be explained by the wings being rolled over slightrly. Perhaps the fly had only just emerged? The fact that it was not near water is not a problem, as several species of Hydrellia are stem miners of grasses rather than aquatic plants. As for fly number 2, I don't think it is Chloropidae. Somehow it is not compact enough (wrong jizz  !) My suggestion is Sepsidae, probably Saltella sphondylii.

Ah, stem miners in grasses. There certainly were abundant grasses nearby. Thanks Tony! --Stephen Stephen Cresswell www.americaninsects.net |

I think Tony is right about N2. I've always seen Saltella wirh red parts of legs or body, but according Ozerov's description Saltella may be completely black as well. Nikita Nikita Vikhrev - Zool Museum of Moscow University |
