why frass?

It's not a bad photo, and I hope you realize that when the photo disappears, all comments and their contained links disappear also.

I can move back

There was a big forum discussion that was brought to my attention that talks about having redundant and non-representative images being posted to BugGuide, so I went through all my photos last night and frassed all the ones that seemed to be "un-necessary".
http://bugguide.net/node/view/136614
I apologize for not looking at the links on this one, so will move back. I was a little irked last night because I keep reading comments about the quality of submissions going down in the past year (and I have been posting for about a year, now), and I guess I took it a little personal...
Sorry, tonight I'll go through my frassed images and see if there are any comments and links that I need to keep.

I've been unable to find info

that describes the difference between Hesperophylax and Psychoglypha species. Both seem to be mainly western genera, based on these distribution lists: 1, 2.

A photo labeled Psychoglypha avigo from the Ken Gray collection in Oregon here, and a shot of a "Snow Sedge" (P. alascensis) from Alaska halfway down this page look quite similar to pics of Hesperophylax species here: 1, 2, 3.

Another pic labeled Psychoglypha here looks fairly different... I wonder how variable these genera are - and how reliable are the IDs of these photos?

Hesperophylax v Psychoglypha

Robin - These two genera can be difficult to separate depending on the photo. A general approach is that the Hesperophylax base wing color is brown and Psychoglypha's (the species with the white stripes - not all have them have stripes)is more reddish or very dark. Of course color depends on the accuracy of the photo and quality of the specimen. Once you get alot of experience you will note the difference in how the white/black stripes extend to the end of the wing and the determination is easier. If the photo is real good you will be able to see the differences in the wing venation.

The Ken Grey photo (and the photo of this thread) are Psychoglypha. The 3 you listed as Hesperophylax are Hesperophylax with the first the best photo. The photo at the end of your message that you indicate seems different, is different. It is neither Hesperophylax nor Psychoglypha, but probably Limnephilus.

The note on "Snow Sedge" applies to Psychoglypha as they are often seen on warm winter days along streams and on snow if present. I have seen Psychoglypha flying in the morning sun while the temperature was at least 5 degrees below freezing.

But, Hesperophylax is common at springs and occasionally adults do emerge in the winter months in these spring habitats.

Hesperophylax sp.

This specimen is in the genus Hesperophylax (Limnephilidae family if I recall correctly). Neat insect!

Yes, it is

I just couldn't get it to stay still at a lower elevation. I even grabbed it and tried to get one with it in my hand, but it just kept wanting the high ground.
Thanks for the ID. I don't see these often.
