Larvae are flattened and brown in color, and they are roach-like in appearance because of the expanded thoracic plates covering the bases of their legs, heads, and abdomens.

No dense tufts or branching gills are found on their thoraces or abdomens, unlike other Plecoptera families.

Male epiprocts are sclerotized and rod-like in shape, and both sexes lack cross-veins in the anal lobe of the forewings.

Roach-like stoneflies are generally found in leaf litter and debris piles trapped in either riffles or pools.

The body of this stonefly is flattened and streamlined to aid in minimizing water resistance in a flowing stream.
