Net-winged Midge

Adults are typically found near rushing, high-gradient mountain streams where their larvae develop.

Larvae graze on algae and diatoms on submerged rocks. Adult diets are less understood, though some species are known to prey on smaller soft-bodied insects.

Larvae are uniquely adapted to torrents using ventral suckers to grip rocks. Adults are often found resting on the undersides of leaves or bridge structures near water.

They pose no risk to humans as they do not bite or sting. They are beneficial indicators of high water quality and serve as a food source for fish and birds.
