| Abstract: | The life history of Boyeria irene is inferred fromsize-frequency analyses of sweep-net samples taken during fiveyears in a permanent stream in the Sierra Morena Mountains.There the species is apparently mainly semivoltine, although a fewlarvae require three years to complete development. The instardistribution during winter is that of a  summer species (sensuCorbet, 1954). Metamorphosis is confined to spring and thereis a long flying season. Similarities between B. ireneand congeneric species in North America are discussed. |
