Hex Mayflies
Hexagenia limbata
The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large Brown Trout that only touch streamers for the rest of the year.

Caddisfly Genus Nectopsyche (White Millers)
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.

3 Streamside Pictures of Nectopsyche Caddisflies:
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.

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.
