Boatman Fly - Pogonortalis doclea

Family Platystomatidae

This page contains pictures and information about Boatman Flies that we found in the Brisbane area, Queensland, Australia.
 
Body length 5mm
 
This fly, when walking, swings it wings like someone swinging the paddles when rowing a boat. We believed this is why they are called Boatman Fly. Those characteristic movements are often seen in this species although they can be seen in other Signal Fly species as well.

This fly is small in size, walk with wing open and has the narrowed waist. We believed this fly mimic ant. One thing interesting is that another ant-mimicking fly, the Ant Fly, is also walk with wings open.
