|The fly life cycle is composed of four stages: egg, larva (commonly known as a maggot), pupa, adult. The eggs are laid in decaying flesh, animal dung, manure, or pools of stagnant water - whatever has ample food for the larva.|
Some types of maggots found on corpses can be of great use to forensic scientists. By their stage of development, these maggots can be used to give an indication of the time elapsed since death, as well as the place the organism died. The size of the house fly maggot is 9.5-19.1mm (3/8 to 3/4 inch). At the height of the summer season, a generation of flies (egg to adult) may be produced in 12-14 days.
Maggot identification uses a classification called "Instar" stages. An instar I is about 2-5 mm long; instar II 6-14 mm; instar III 15-20 mm. These measure about 2-3 days, 3-4 days, and 4-6 days (for average house flies or bottle flies) since the eggs were laid. By use of this data, plus other signs, the approximate time since death can be estimated by forensic scientists.
The world's rarest known fly families include the Eurychoromyidae, Broad-headed Flies and the Boston Red-Tinted Warbler Flies. While the first family is harmless to human life, the second is known for attacking warm-blooded bodies, especially any exposed skin of humans.
