Wing length 2 mm
Generally brown with white legs and halteres. Male has white patches on the side of some abdominal segments, approximately triangular with point forward. Genital features may be necessary to confirm ID. Most of the males here have tergite 5 pale on top, which is not the usual color pattern. The exception is from spring; midges that develop in cold water are often darker.
