Abstract

Thirty species in 11 genera of Hydroporinae were collected in Wisconsin over the past 32 years, excluding those in Hydorporus s.l. Fourteen species of Hygrotus were found; other genera were represented by one to four species. Species keys and notes on identification are provided for adults of all species that occur or may occur in Wisconsin. Information on distribution and abundance in Wisconsin, habitat, and life cycle is provided for each species based on a study of 34,628 adults. Life cycles were predominantly univoltine, with adults overwintering and larvae completing development from late spring to late summer, depending on the species. Most adults apparently overwinter in aquatic habitats, except those of Laccornis and Hygrotus compar, which probably overwinter in terrestrial habitats.
