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.

It is my understanding that wing maculation is quite distinctive and consistent in this genus thus allowing species identification using this character. This specimen has been at the genus level for many years and somehow slipped through the cracks.;)

Where did the name "White Miller" come from, for the caddis bug in the warm Yellowstone waters? I am not interested in the east coast mayfly with the same name. Thanks, Mike Miller.
