Abstract |
Larvae of the caddisfly genera Hydropsyche and Symphitopsyche are among the most encountered and abundant organisms of lotic environments in eastern North America. Yet, little is known of the larval stages of these genera. Previously, the larvae of only 12 species of which descriptions are presented here, were known. Descriptions of larvae of an additional 27 species are here presented for the first time. Presented here are the descriptions of the larvae of 14 of 15 nominal eastern species of the genus Symphitopsyche, and 25 of 34 of the genus Hydropsyche; 18 of 24 of the scalaris group, 6 of 9 of the depravata group, and the single species of the cuanis group, H. cuanis. A key is provided for known larvae, incorporating a number of characters previously unused in the taxonomy of these two genera. The key is based on ultimate or penultimate larval instars since color patterns may be more variable in earlier instars. A listing of all unassociated species, with known distribution and literature citations, is given. |
