The bluebottle fly or bottlebee (Calliphora vomitoria) is a common blow fly found in most areas of the world and is the type species for the genus Calliphora. Similar species include the greenbottle fly, a close relative that can be distinguished by its bright green metallic colouring. Bluebottle fly adults feed on nectar, while the larvae feed on carcasses of dead animals. Adults are also pollinators to some flowers with strong odor.
