Abstract

Hexagenia limbata are burrowing mayflies that inhabit the Great Lakes and their connecting channels. The objectives of this study were to quantify the differences in seasonal adult emergence patterns between sexes and species. The final objective was to examine egg and nymphal development as a response to emergence date and temperature as well as the degree of plasticity displayed in their development. Adult mayflies were collected for 2 h at sunset from quadrates placed on land near dock lights at Colchester Harbour, Lake Erie, throughout the emergence period, June through August. In the laboratory I conducted a reciprocal transplant experiment in which survivorship and growth of organisms were examined at temperatures, representing early (20°C) and late (25°C) cohort development. Additionally, eggs from three populations (Lake Erie, Lake St. Clair, and Detroit River) and across the emergence period were reared in temperatures ranging from 16--28°C representing the natural range indicative of summer conditions.
