Life cycle and secondary production of Caenis sp nymphs were analysed during one year of study in Lake Escondido, in relation to depth, water temperature and vegetation distribution. Higher densities of nymphs were found in the upper littoral zone with Schoenoplectus californicus (2665 ind m-2), compared to lower littoral covered with Potamogeton linguatus (29 ind m-2) and the profundal (4 ind m-2) zones. During the study this mayfly was univolotine with one emergence in summer. The highest production (0.67 g m-2 yr-1) was obtained in the S. californicus zone and it was related to the highest values of organic matter content and water temperature in the shallower area of the lake.
