Signal Flies - Family Platystomatidae

This page contains pictures and information about Signal Flies that we found in the Brisbane area, Queensland, Australia.
Body length 12mm
Most flies in this family feed on mammalian faeces. Their larvae habits are varied. Some lives in plant trunk damaged by other insects or fungi. 
This group of flies contains the spectacular species, the stalk-eyed signal flies. The males have eyes on long stalks extending from either side of their heads. But we never saw them in Brisbane.
