Habitat
The larvae of this species are found in small-medium, high gradient mountain streams (Newell and Minshall 1978), and are indicators of the Pristine Mountain Stream Ecological System (Stagliano 2005). Most Nemouridae species are shredders or collector-gatherers utilizing coarse plant materials (Merritt and Cummins 1996).

Food Habits
Merritt and Cummins (1996) report that members of this family are trophically shredder-detritivores; eating large particulate organic materials such as detritus, leaves and plants.
