Abstract
The mayfly, Cloeon sp. was studied in a small lake in Shillong, North Eastern India from April 1991 to March 1992 with respect to its seasonal abundance, life history and feeding habits. Nymphal density was largely governed by temperature and probably to some extent by predation and food availability. Nymphal development was poorly synchronized with rapid growth and continuous recruitment except in the winter months. The emergence of adults also ceased during December to February. Nymphs were herbivore-detritivores and exhibited a seasonal shift in the composition of their diet. Filamentous green algae and desmids were the dominant food materials during April to October, while during November to March, detritus and flagellates constituted the major items.
