Abstract

About 59,000 aquatic Hemiptera were collected in Wisconsin, most of them in the last 15 years. These include three species of Belostomatidae, 48 species of Corixidae, one species of Naucoridae, four species of Nepidae, nine species of Notonectidae, and one species of Pleidae. The riparian Gelastocoris oculatus was also found. Species keys for adults are provided along with notes on identification, habitat, biology, distribution, and abundance. Most species reached peak abundance in late summer and autumn and overwintered as adults, but seven species apparently overwintered as eggs. Most lentic species flew to streams or larger len tic habitats to overwinter. Populations of all species declined rapidly after mating and oviposition in the spring.
