     src= Mating pair

    The Micropezidae are a moderate-sized family of acalyptrate muscoid flies in the insect order Diptera, comprising about 500 species in about 50 genera and five subfamilies worldwide, (except New Zealand and Macquarie Island). They are most diverse in tropical and subtropical habitats, especially in the Neotropical Region.

    Insects in this family are commonly called stilt-legged flies, after their characteristically long legs. The fore legs are markedly smaller than the other pairs. Mostly, they are long-bodied, often black flies, usually with infuscated (darkened) wings. Wings are reduced in the genera Calycopteryx and entirely absent in the ant-like Badisis ambulans.

    Adult micropezids (Stilt Flies) often live on foliage or tree trunks in forested areas and some are attracted to fresh mammal dung. Males of the wingless Badisis ambulans McAlpine run on flowering branches of Astartea (Myrtaceae) with the ants that they mimic. Larvae are little known but some live in underground plant parts or decaying wood. Those of Badisis ambulans live in the pitchers of the insectivorous plant Cephalotus in south-western Australia. This family contains wingless flies.
