Stilt-legged Fly

Description:

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.

Habitat:

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. Little is known of the larval habits, but they are probably phytophagous or saprophagous in decayed vegetation, old manure, or fungi . Larvae of certain Mimegralla species have been found to live in the roots of ginger and other plants, under the bark of dead trees, or in other decaying material. Adults are either predatory on small insects or are attracted to excrement or decaying fruit. Adults are found on low herbage, flowers, leaves, rotting fruit, and excrement. Many species (for example those of genus Mimegralla) are known for their habit of standing motionless while waving their prominently marked front legs in front of their heads, a behavior which contributes to their mimicry of wasps.
