long winged fly
June 5, 2009
Found this last night sitting on the window sill near the side porch. It was not alarmed by me getting quite close to it, it did not move much at all. It was between 1.5 and 2 inches long.

We are catching up on old mail, and there are some gems we never had the time to address. Your photo is one of those. This is a Caddisfly in the order Trichoptera. The adults are often compared to moths, and the aquatic larvae are known as Caseworms. We believe your large Caddisfly is Hydatophylax argus, a species with no common name, but in the family Limnephilidae, the Northern Caddisflies. You can see some matching images on BugGuide.
