The green bottle fly (Phaenicia sericata) is a common blow-fly found in most areas of the world. It is 10-14 mm long, slightly larger than a housefly, and has brilliant, metallic, blue-green or golden colouration with black markings. It has black bristle-like hair and three cross-grooves on the thorax. The wings are clear with light brown veins, and the legs and antennae are black.
Life cycle A mass of up to 180 eggs are laid in wounds, carcasses, or necrotic tissue. Pale yellow or grayish-white larvae 10-14 mm long hatch in half a day to three days, and begin feeding on the decomposing animal matter they were hatched in. They are fully grown in two to ten days, when they will seek soil in which they will burrow to pupate. The adults emerge to mate, beginning the cycle again. During cold weather, pupae and adults can hibernate until warmer temperatures revive them. They are also found in America but they are harmless, just like houseflies. They are pollinators of some flowers with a strong odor such as pawpaws and goldenrod. | |||||||||||||||||||||||||||||||||
