Scorpion fly - Panorpa insolens - Female

Female scorpion fly? That's my first guess. It has the long "face", as in this one: http://bugguide.net/node/view/81626

Moved from Panorpa.

This is Panorpa insolens (pre
This is Panorpa insolens (previosly helena) based on the lack of submarginal spots, the locality, and time of year.

i agree
That's what it looks like to me. A couple weeks ago I found a lot of them out. There seems to be fewer now. The males have an interesting wing rotation, showing off behavior, I assume to attract the girls.

 
species
I can get some better pictures, looks like there are a lot species in the panorpa genus.

 
wing pattern
I think the wing pattern is helpful in narrowing it down, so this top down shot is good for that. I'm not sure what other features would be diagnostic though.

 
Panorpa species
Joe, when trying to ID a scorpionfly from last years, INHF Bioblitz it was pretty easy to get to genus, but the keys to figure out species that I found online had to do with the mouthparts from the lower side. Even with the pinned specimen under a scope I was not sure what I had. Perhaps there is a Mecoptera specialist that could help us out with species ID. Here are my posts.

Thanks
I also found this set of plates with illustrations of mecoptera wings for several of the species of Panorpa http://www.biology.ualberta.ca/bsc/ejournal/cmw01/panwing.html
