A caddisfly in the front yard

This is an adult of one of the large caddisflies (Family Phryganeidae, Order Trichoptera), very likely the species Agrypnia. It was sitting on a large cranesbill geranium in my front yard, and allowed me to hold it in my hand. The larvae of this family live underwater and build smooth tubular cases from which they feed.
