Midge, a tiny two-winged fly that resembles a mosquito. Midges lay their eggs in freshwater or saltwater, under tree bark, or in damp organic matter. The larvae live wholly in water or in soft earth or mud. The punky, no-see-um, or biting midge, is about 1/25 inch (1 mm) long. It is the smallest blood-sucking insect known. It is common in damp areas and woods, and inflicts painful bites on both humans and animals.

The punky genus is Culicoides of the family Ceratopogonidae and order Diptera. Other midges belong to the families Chironomidae and Cecidomyiidae.
