Cecidomyiidae (predator midges)

This family contains around 5,000 species of small, often tiny flies, usually ½ to 4 mm long. Most are plant parasites and construct galls. However, the larvae of some species are insect predators and these are covered here. Adults only live for a few days and often do not feed.

The adults are mosquito-like with long legs and long antennae. They are usually yellow, orange or red in colour, hairy and with large wings. The antennae have around 15 segments, including 2 characteristic basal ones, with whorls of hairs. The compound eyes meet above the antennae.
