Excerpt: Adult chironomid midges are well known to visitors at northern Wisconsin lakes during the spring and summer. Although the larval stages of chironomids supplement the diet of fish, the adults are often a nuisance because they aggregate in huge aerial swarms near beaches, collect at lights, alight on various objects including people, and deposit green specks wherever they rest. The most familiar midge in Wisconsin is Chirononmus plumosus (L.) which has been studied at Lake Pepin (Johnson and Munger, 1930) and at Lake Winnebago (Burrill, 1913; Hilsenhoff, 1959,1966,1967).
