They inhabit virtually the entire range of aquatic ecosystems, both fresh and marine, as well as semi-terrestrial and terrestrial habitats.
Most species have aquatic wormlike larval stages that start as egg masses laid on the water surface.
After going through a pupal stage, floating at the surface of the water, a full-grown midge emerges and flies away. All Rights Reserved . No images, graphics, software, scripts, or applets may be reproduced or used in any manner without permission from the copyright holders.
