Ceratopogonidae, or biting midges (including what are called, in the United States, no-see-ums, midgies, sand flies, punks, and others), are a family of small flies (1–4 mm long) in the order Diptera. They are closely related to the Chironomidae, Simuliidae (or black flies), and Thaumaleidae.What a horrible, little pest of a fly. I've never felt rage for another living thing like I did for the no-see-ums on Cape Sable in Everglades National Park.
