Aquatic Critters
Stonefly

Stonefly NymphStonefly nymphs are found under stones and amongst debris in clean, cool, running water and indicate good water quality. They are multicolored with black, brown, tan and yellow, and have two tail filaments. 

Stonefly NymphWhen small, stonefly larvae feed on dead plant material and one celled organisms (protozoans). As they grow larger they become predators, ingesting their prey whole. They are, in turn, an important food for fish. The adult has transparent wings with visible veins and is gray and brown.
