The Greenbottle Fly (Lucilia caesar) is a small insect in the Calliphoridae family of blow flies. It is also known as the Common Greenbottle Fly.
The Greenbottle Fly has a metallic iridescent green 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.
The Greenbottle Fly is found in Europe, North America, South America, Africa, Australia, and New Zealand. It prefers urban areas.
It is diurnal, active during the day.
The larvae (maggots) feed on dead animals, and the adult flies feed on pollen and flower nectar.
The female Greenbottle 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 (form a casing). After 11 days, they metamorphose into an adult fly.
