General Description

This species of the family Perlidae is a predaceous stonefly, eating other aquatic insects-especially midges, blackflies and small mayflies. They live on the cobbles and boulders of medium to fast flowing streams.

Food Habits

Merritt and Cummins (1996) report that members of the families, Perlidae and Perlodidae, are largely predators eating other aquatic invertrebrates, especially Diptera (Chironomidae and Simuliidae, midges and blackflies) and Mayflies.
