General Description

This is a small black stonefly in the family; Leuctridae. Like most of the species in the rolled-winged family, this species hatches early in the year often when snow is still on the ground, where they can be noticed quite easily crawling around along the banks of streams.

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.
