Abstract

The study of the larval development and life cycle of a population of the mayfly Anthopotamus verticis from the Tippecanoe River, Indiana was based on monthly and weekly sampling in 1990 and 1991. Larval head width and tusk length were directly correlated with body size; whereas wingpad development represented an exponential relationship with body size. Relative maturation of larvae was efficiently assessed, however. by using wingpad development. The morphology of eggs is described. Larval growth and development took place mainly from March to Au~st. Although emergence is protracted from mid-July to mid-August, the major recruitment of new larvae occurred in August. Only one cohort was ascertained. The species overwinters as mostly young larvae. The simple univoltine life cycle appears to be related to seasonal temperature.
