Chironomidae (informally known as chironomids or non-biting midges) are a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes but they lack the wing scales and elongate mouthparts of the Culicidae. This is a large group of insects with over 5000 described species and 700 species in North America alone. Males are easily recognized by their plumose antennae. Adults are sometimes known as "lake flies" in parts of Canada, as "sand flies", "muckleheads"[1], or "muffleheads"[2] in various regions of the USA Great Lakes area, and as "blind mosquitoes" in Florida, USA.

[edit] Behavior and description
Adults can be pests when they emerge in large numbers. They can damage paint, brick, and other surfaces with their droppings. When large numbers of adults die they can build up into malodorous piles. They can provoke allergic reactions in sensitive individuals.[3] Larvae are important as food items for fish and other aquatic organisms. They are also important as indicator organisms, i.e., the presence, absence, or quantities of various species in a given body of water can indicate whether pollutants may be present. Their fossils are also widely used by palaeolimnologists as indicators of past environmental changes, including past climatic changes.[4]
Larvae can be found in almost any aquatic or semiaquatic habitat, including treeholes, bromeliads, rotting vegetation, soil, and in sewage and artificial containers. Larvae of some species are bright red in color due to hemoglobin; these are often known as "bloodworms".[5]
[edit] Subfamilies and genera
The family is divided into eleven subfamilies: Aphroteniinae, Buchonomyiinae, Chilenomyinae, Chironominae, Diamesinae, Orthocladiinae, Podonominae, Prodiamesinae, Tanypodinae, Telmatogetoninae, Usambaromyiinae.[6][7]
