Freeloader Flies - Family Milichiidae and Chloropidae

This page contains pictures and information about Freeloader Flies in Family Milichiidae and Chloropidae that we found in the Brisbane area, Queensland, Australia.
Milichiidae and Chloropidae are two very close related Diptera families. Some species in family Milichiidae and Chloropidae can be found gathering around feeding spider or some other predator insects in order to feed on their prey.
Gerard Pennards saw the photos in our old web pages and email us this comments: "I would say these were Desmometopa sp. of the Family Milichiidae! These are known to show this 'kleptoparasitism'.  And the there are also sometimes Chloropids which show this behaviour."

Freeloader Fly I

? Desmometopa sp. family Milichiidae, body length 2mm 
This small fly has the 'kleptoparasitism' feeding habit. They were found around the Salticid Ant Eater jumping spider when the spider was feeding on ant. We believe the fly feeds on the juice of the ant which was externally digesting by the spider. Please check this page for more information.
Freeloader Fly II
