Abstract

The samples of emerging stoneflies obtained using slit traps indicated a three-phase course of emergence : early spring(two winter stoneflies), early summer (especially Perloidea) and autumn (a few abundant Nemouroidea). Early June andmiddle August are recommended as the sampling periods for benthon as far as stoneflies for bio-index studies are concerned.
