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.
