Name: Common Green Bottle Fly (Lucilia sericata)
Description: A blow fly found in most areas of the world, and the most well-known of the numerous green bottle fly species. It is 10–14 mm long, 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 clear with light brown veins, and the legs and antennae are black. The (larvae) of the fly may be used for maggot therapy.
Distribution: Common all over the temperate and tropical regions of the planet, mainly the Southern Hemisphere: Africa and Australia.
Lifespan: 2 to 3 weeks
Lifecycle: The larva feeds on dead or necrotic tissue for 3 to 10 days, depending on temperature and the quality of the food. During this period the larva passes through three larval instars. At a temperature of 16 °C, the first larval instar lasts about 53 hours, the second about 42 hours and the third about 98 hours. At higher temperatures (27 °C) the first larval instar lasts about 31 hours, the second about 12 hours, and the third about 40 hours. Third-instar larvae then drop off the host onto soil, where available, where they enter a pupal stage which usually lasts from 6 to 14 days. However, if the temperature is suitably low, a pupa might overwinter in the soil until the temperature rises. After emerging from the pupa, the adult feeds opportunistically on nectar or other suitable food, such as carrion, while it matures. Adults usually lay eggs about 2 weeks after they emerge.
