Limnephilus
where on Buffalo Creek did you get this?

1km S of
Buffalo Creek Campground - in a small runoff stream that tributes to Spring Creek.

that didn't help
what is bothering me is this looks like a fairly high alt critter in CO. and I don't know a spring creek trib to Buffalo Creek. Do you have a lat/long?

Latitude = 39.3277, Longitude = -105.2859
as far as I can tell - I didn't mark the point with a GPS.

Thanks
that helps - I guess I need to get up there - did you keep the critter? Are lots of the setae on the fore wing membrane (not the veins)long and upright? The more I look at it, it may not be Limnephilus.

What do you think of
Hesperophylax? I find a lot of those larvae up there.

not likely
but could be close - if you kept it you can tell real easy by the upright membrane setae, they are recumbent in Hesperophylax and Limnephilus (sensu stricto). No way to tell from the photo. Also, Hesperophylax almost always has a much longer pale area between the discoidal and thyridial cells, and it usually appears silver.

What I was thinking was Psychoronia but it would be the lowest altitude collection I am aware of. Psychoronia and Crenophylax larvae are very similar to Hesperophylax but are probably most easily separated by the lack of spicules on the pronotum. Psychoronia also lacks spicules on the head.
