Life cycle

During the spring and summer males will create mating swarms which people can find quite a nuisance even though adults do not bite, or feed. Females will lay egg masses in water where the egg mass will grow and sink to the bottom. The larva stay at the bottom in silken tubes. The larva feed on organic material such as organic debris and algae.
