 the bed of the stream or under the edges of rocks, the belly pressed in close 

 contact with the bottom. The food is composed of entomostraca and small 

 Crustacea, with occasional insects, stonefiy larvae and small dragonfly 

 and mayfly nymphs, Chironomus and Simulium larvae, and rarely a small 

 mollusk.
