Abstract:

Eighteen species of Rhyacophila were found in the Salmon River drainage of Idaho in collections made during 1964, 1965, and 1966. The larvae of Rhyacophila acropedes Banks, angelita Banks, Bifila Banks, coloradensis Banks, hyalinata Banks, oreta Ross, rotunda Banks, tucula Ross, vaccua Milne, vagrita Milne, vao Milne, vepulsa Milne, verrula Milne, and vocala Milne were found and are described and figured. Distributional and bionomical data are presented for most species. Some of the Rhyacophila species encountered exhibited differences in their seasonal occurrence. Differences in adult diurnal activity periods also were noted and are recorded. An attempt was made to evaluate the preferred larval habitat of each species, but information was not sufficient to permit definite conclusions.
