I think this is a particularly nice looking Doli. Can anyone ID it beyond the family level? Is it possible to tell the sex from the photo? At the edge of a pond, surrounded by woodlands, West Virginia USA, 24 July 2006.

This is Pelina (Ephydridae) - my Nearctic keys are at work, so I'll need to get back to you on this. Female I think.

My ID of the three flies I posted today were Muscidae, Dolichopodidae, and an unknown. With your guidance I learn that in fact they were Anthromyiidae and two Ephydridae.  As always I appreciate your help with these. I am learning so much! I must admit on this one I jumped to a conclusion based on the bronzy color that seemed right for a Dolichopodidae, and habitat that also seemed right. Since the fly was on a shore, though, I should have also thought of Ephydridae (Shore Fly)! Edited by Stephen on 30-10-2006 11:01 --Stephen Stephen Cresswell www.americaninsects.net |

Ooops!. You know those picture puzzles which show you a common object from an unusual angle? ... This isn't Pelina, but rather Ochthera. As it has its mantid-like forlegs hidden, I was un.. [that's no excuse! - I should have noticed the thickness of that front femur!] In Clausen's revision of the genus, two species are recorded from West Virginia, and the dark front tarsi suggest that this is O.anatolikos. This should be regarded as a provisional det., since other species might well occur there and many are difficult to separate without recourse to genitalia studies. Tony ---------- Tony Irwin |

Thanks for the update, Tony. I've changed my records. I'm also going to change the title of this post so it no longer says Dolichopodidae! Mantid-like front legs? I can see this is another species I am going to have to crawl on my belly in the mud for, to photograph it in profile! --Stephen Stephen Cresswell www.americaninsects.net |

It's well worth it - see http://www.dipter...oto_id=560, although admittedly Nikita's mud was probably a bit warmer than yours!

Very cool, like a Mantid version of Arnold Schwarzeneggar (who was reelected governor of California yesterday, by the way)!

Yep, it's all there - massive fore-limbs, very photogenic, great tan, tiny intellect.  [ Can I say that Paul? or have I breached the code? ] Tony ---------- Tony Irwin |

While I know we don't want to get into politics, surely an off-hand comment about a movie star isn't amiss.
