The buzzer midge gets its name from the characteristic sound made by its wings, which vibrate around 1,000 times per second in flight. This non-biting midge is around 10 millimetres in length, and green, grey, yellow and black in colour. Males have conspicuous feather-shaped antennae. The larvae live in silt at depths of up to 300 metres.
The buzzer midge is a common and widespread species. Its larvae can be found in rivers and streams, as well as in tree hollows, manure and other moist materials.
Adults do not feed and have only rudimentary mouth parts. Larvae feed on organic debris and microorganisms. Buzzer midges are harmless to humans.
