Midges in the Chironomidae family do not bite like the pesky mosquitoes they resemble. That doesn't mean they don't sometimes ruin outdoor fun.
Midges are often mistaken for mosquitoes thanks to similar size and body shape. Because they do not take blood meals, they are also known as Blind Mosquitoes. Male Midges tend to have feathery antennae, something not seen on mosquitoes. Also, midges rest with their two front legs hovering above the surface, whereas mosquitoes lift their hind legs.
Midges can be found along the coast, shores and beds of any body of water. Lakes and ponds will often see huge congregations of them. Thanks to poor flying ability, they are often at the mercy of wind currents and can be blown into backyards. For this reason, they may be considered a nuisance to homeowners. They may take shelter under soffits, eaves, or covered patios. They do seem to be attracted to artificial lights at night and many homes are also lit in those places. This in turn may attract predators of Midges like spiders to those areas. Adults have very short life spans (only a few days) so their presence is not permanent.
Eggs are laid in shallow waters. Worm-like larvae hatch and serve two good roles in the ecosystem: as a cleaner (consumer) of decaying organic matter in the water and as a food source to other aquatic insects and even fish. Adults do not feed and spend their short lives mating.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
