Calliphora vomitoria (Linnaeus, 1758)

Blue bottle flies, Calliphora vomitoria (Linnaeus, 1758) (Diptera: Calliphoridae) are found throughout most regions of the world. Adults are metallic blue or some variation, and slow fliers in comparison to the green bottle flies. They are active during cooler temperatures (<20 °C) and are known to colonize a variety of decomposing materials; however, typically they are associated with decomposing vertebrate tissue. Blue bottle flies have a complete life cycle with an egg, larva, pupa, and adult. Development usually needs approximately two weeks to be completed. Larvae are high in protein and potentially can be used as feed.
