The common name White Miller is usually applied to this entire genus, although it was created for the very prolific species Nectopsyche albida. Some of the other species are darker-colored.

Most of the adult activity, both emergence and egg-laying, takes place during the middle of the night. There is some rare overlap with the low-light hours of dusk and dawn, but this genus really belongs to the night fishermen.

These caddisflies were thick over the water in the evening on a cold, clear northwoods lake. They were in many places on the lake, all closer to the shady shore, which also was the shore most sheltered from the wind. I'm not sure which of those features attracted them.
