Stilt Flies

Description:

moderate-sized family of acalyptrate muscoid flies in the insect order Diptera, comprising about 500 species in about 50 genera and 5 subfamilies worldwide. 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:

known for their habit of standing motionless while waving their prominently marked front legs in front of their head, a behavior which contributes to their mimicry of wasps

Notes:

saw this at a papaya tree only during dawn.....
