Blue Fly

The Blue Fly (Calliphora vicina) is a small insect in the Calliphoridae family of blow flies. It is also known as the Blow Fly, the Bottle Fly, or the Blue Bottle Fly.

The Blue Fly has a metallic iridescent blue colour on its thorax and abdomen. It has bright orange cheeks. It has black bristles (small hairs) on its body. 

It measures about 1 centimetre (half an inch) long. 

Blue Fly

The Blue Fly is found in Europe, the Americas, Africa, Australia, and New Zealand. It prefers urban areas.

It is diurnal, active during the day. 

The larvae (maggots) feed on earthworms, and the adult flies feed on rotting meat and manure. 

The female Blue Fly lays up to 300 eggs on fresh dead animals or on open wounds of animals. Within 24 hours, the eggs hatch into larvae called maggots. The maggots feed on the meat of dead animals for 3-4 days, then pupate (forma a casing). After 11 days, they metamorphose into an adult fly.
