Popis:	From analyses of monthly length frequency distributions, univoltine life cycles were described for Sialis dreisbachi, Stenonema vicarium, and Dicranota sp. from stream riffles. Stream drift of immature S. dreisbachi and S. vicarium peaked near the ends of their life cycles in the spring. Drift of these two species was not related to standing stocks. Dicranota larvae exhibited negligible drift rates.
