Blowfly - Family Calliphoridae

This page contains pictures and information about Blowflies that we found in the Brisbane area, Queensland, Australia.

Body length 8mm
Most of the flies in this family are metallic green or blue colour. Others are mixtures of brown and and dark grey. They are medium to large in size. There are the bristles on the both sides of their thorax and abdomen tip. 
Adult Blowfly feeds on nectar, honey dew and other sweet liquid, or liquid products of organic decomposition. Most Blowfly adults active during day time.
Blowfly larvae usually live in carrion or dung, which help for decomposition. Some species are parasitic on earthworms or land snails. Some live in termites or ants nest.
