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?

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. :D

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)!

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.

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!

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

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. ;)

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