Cheumatopsyche
Posted by Litobrancha on Oct 20, 2006
a great thing about cheumatopsyche (which i believe this is) is that the IX segment ventral plates are almost always completely differentiated to the base. hydropsyche medial margins are more indistinct near the base.

also cheumatopsyche almost always lacks F1 in the hind wings, although aberrant specimens are common. the best character is the distance between M and Cu veins in the hind wing, other hydropsychids are parallel and close together, cheumatopsyche diverges a bit.

Really cool pictures, Jason. My first impression was classic Cheumatopsyche (Little Sister Sedge), and I can't find anything to indicate otherwise--size, color, maxillary palp, and wing all seem right on. Wish I could help with the species, but with many caddisflies I'm happy just to get the genus right. :)

It is interesting to note that some books say that the coloring of many Cheumatopsyche species gets lighter as the season progresses. That certainly doesn't seem to be the case here.
