Common Green Bottle Fly (Lucilia sericata)

Common Green Bottle Fly

The common green bottle fly (Lucilia sericata) is a blowfly found in most areas of the world and is the most well-known of the numerous green bottle fly species. Its body is 10–14 mm (0.39–0.55 in) in length – slightly larger than a house fly – and has brilliant, metallic, blue-green, or golden coloration with black markings. It has short, sparse, black bristles (setae) and three cross grooves on the thorax. The wings are transparent with light brown veins, and the legs and antennae are black. The fly’s larvae may be used for maggot therapy, are commonly used in forensic entomology, and can cause myiasis in livestock and pets. The common green bottle fly emerges in the spring for mating.

Lucilia sericata is common all over the temperate and tropical regions of the planet, including Europe, Africa, and Australia. It prefers warm and moist climates, so it is especially common in coastal regions, but can also be found in arid areas.[The female lays her eggs in carrion of all kinds, sometimes in the skin or hair of live animals, causing myiasis. The larvae feed on decaying organic tissue. The fly favors host species of the genus Ovis, domestic sheep in particular, and sometimes lays eggs in the wet wool of living sheep. This can lead to a blowfly strike, causing problems for sheep farmers. L. sericata has been known to prefer lower elevations relative to other Calliphoridae species, such as Calliphora vomitoria.
