Abstract
Data on food habits were obtained for 20 spp. [Caudatella cascadia, C. hystrix C. edmundsi, C. heterocaudata, Serratella teresa, S. tibialis, S. velmae, Ephemerella infrequens, E. inermis, E. verruca, E. aurivillii, Drunella spinifera, D. doddsi, D. pelosa, D. coloradensis, D. grandis, Attenella delantala, A. margarita, Eurylophella lodi, Timpanoga hecuba] in the mayfly family Ephemerellidae. Diet of a species often varied with site, habitat and size, but such variation did not completely mask differences among species. Adaptive radiation in diet is relatively great in this family, but species showed no distinct groupings when classified either on a functional basis or by traditional trophic categories.This publication has 4 references indexed in Scilit:
