Caddisfly Species Brachycentrus occidentalis

These are often called Mother's Day Caddisflies.
Gary LaFontaine tells the story in Caddisflies of how this species came to awareness through rumors of a widespread, intense hatch of an undentified brown and green caddisfly throughout the West. He traveled across the West collecting these flies and determined that they were Brachycentrus occidentalis.
