Midge (insect)
Overview
Midges comprise many kinds of very small two-winged flies found world-wide. The term does not encapsulate a well-defined taxonomic group, but includes animals in several families
Family (biology)
In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

Diptera
Diptera , or true flies, is the order of insects possessing only a single pair of wings on the mesothorax; the metathorax bears a pair of drumstick like structures called the halteres, the remnants of the hind wings. It is a large order, containing an estimated 240,000 species, although under half...

- BlephariceridaeBlephariceridaeBlephariceridae, commonly known as Net-winged midges, are a nematoceran family in the order Diptera. The adults resemble crane flies except with a projecting anal angle in the wings, and different head shape, absence of the V on the mesonotum, and more laterally outstretched forward-facing legs...
