Maggots feeding on an opossum carrion Maggots on a porcupine carcass Maggots from a rabbit. Common wild pig (boar) corpse decomposition timelapse. Maggots are visible. A maggot is the larva of a fly (order Diptera); it is applied in particular to the larvae of Brachycera flies, such as houseflies, cheese flies, and blowflies, [1] rather than larvae of the Nematocera, such as mosquitoes and ...
The blueberry maggot is closely related to the apple maggot (R. pomonella), a larger fruit fly in the same genus. It is a major pest of plant species in the Ericaceae family, such as blueberry, cranberry, and huckleberry. The larva is 5 to 8 mm long, apodous, and white with chewing mouthparts.
A C. rufifacies adult, the hairy maggot blow fly. The hairy maggot blow fly can be readily identified by examining for a shiny metallic blue-green color, a pale genal dilation, and a vestiture of the anterior thoracic spiracle that is pale in color. The mature adult is about 6–12 millimetres (0.24–0.47 in) in length. [4]
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.
The siphon is usually about as long as the maggot's body (20 mm (0.79 in) when mature), but can be extended as long as 150 mm (5.9 in). This organ gives the larva its common name. [2] The most commonly encountered rat-tailed maggot is the larva of the drone fly, Eristalis tenax.
Informally, such brachyceran larvae are called maggots, [66] but the term is not technical and often applied indifferently to fly larvae or insect larvae in general. The eyes and antennae of brachyceran larvae are reduced or absent, and the abdomen also lacks appendages such as cerci .
The larva is a cylindrical-maggot shape, elongated, with the anterior end narrowed a somewhat curved ventrally. It has anterior mouth hooks, ventral fusiform areas and a flattened caudal end. Last instar larvae range from 7.5 to 11.8 mm in length.
The white-bodied larvae of L. coeruleiviridis develop in three stages, called instars. In each instar, the larva grows larger and larger. Its only function in this stage is eating until the final growth stage to adult fly. The marked differences between each instar are seen in the spiracles of the maggot on the posterior end.
