Common Name
Arctopsyche grandis, the western species, is by far the most important in this genus. It produces excellent fishable hatches.

Larva & Pupa Biology

Diet: Smaller insects
Shelter Type: They spin and tend their nets instead of building a case.
The larvae live for two years before emerging and are especially prone to behavioral drift (Behavioral drift: The nymphs and larvae of many aquatic insects sometimes release their grip on the bottom and drift downstream for a while with synchronized timing. This phenomenon increases their vulnerability to trout just like emergence, but it is invisible to the angler above the surface. In many species it occurs daily, most often just after dusk or just before dawn.) at dawn and dusk.
