Family Micropezidae - Stilt-legged Flies

This page contains pictures and information about Stilt-legged Flies in family Micropezidae that we found in the Brisbane area, Queensland, Australia.
Flies in this family have very long legs, although the front pair is obviously shorter. Their body is elongated with patterned wings. Most are medium in size. They usually mimic either wasps or ants in the body shape. Their behaviour mimic those wasps and ants as well. They wave their fore legs in front of head when resting on plants. 
Some species adults are attacked to human dung and some inhabit flowers.   
Not much is known about the larvae life. It is known in general that they live in decaying wood and other plants matter underground.

Mimegralla australica, body length 12mm 
This fly was found near a small pond in Yugarapul Park. It was walking around on a large leaf seems looking for something. It kept flicking its wings and front pair of legs, trying to convince us that it were a black wasp or ichneumonid wasp. Please check this page for more information.

Metopochetus (Crus) freyi, body length 10mm
Pictures were taken on grasses. Its wing patterns look like an ant's narrow waist and abdomen. The fly walked like an ant too, sometime with jumping action. It might try to mimic the Jumper Ant. Please check this page for more information.
