Abstract

The stonefly Pictetiella expansa has been acknowledged as a species since the 1920s, yet little is known about this rare species of Perlodidae stonefly. The purpose of our study was to document the growth rates and feeding behaviors of Pictetiella expansa in the American Fork River as well as to document its current geographical distribution.
