A report on Histeridae and Maggot

Introducing an environmental control, such as Hister beetles, can also help reduce maggot populations.

- Maggot

Certain species of the Hister beetles follow shortly behind and prey on the maggots and other arthropods present.

Casu marzu is a traditional Sardinian sheep milk cheese that contains larvae of the cheese fly, Piophila casei.

Other species like Metopia argyrocephala are ovoviviparous, opportunistically depositing hatched or hatching maggots instead of eggs on carrion, dung, decaying material, or open wounds of mammals.

Maggots of different species of flies visit corpses and carcases at fairly well-defined times after the death of the victim, and so do their predators, such as beetles in the family Histeridae.

These soon hatch into legless white larvae, known as maggots.

Hister beetles feed on housefly larvae in manure heaps and the predatory mite Macrocheles muscae domesticae consumes housefly eggs, each mite eating 20 eggs per day.

Scientific study of the colonization of a dead body by arthropods.This includes the study of insect types commonly associated with cadavers, their respective life cycles, their ecological presences in a given environment, as well as the changes in insect assemblage with the progression of decomposition.

The accepted theory of Redi's day claimed that maggots developed spontaneously from rotting meat.

Hister beetles – family Histeridae. Adult histerids are usually shiny beetles (black or metallic-green) which have an introverted head. The carrion-feeding species only become active at night when they enter the maggot-infested part of the corpse to capture and devour their maggot prey. During daylight they hide under the corpse unless it is sufficiently decayed to enable them to hide inside it. They have fast larval development with only two larval stages. Among the first beetles to arrive at a corpse are Histeridae of the genus Saprinus. Saprinus adults feed on both the larvae and pupae of blowflies, although some have a preference for fresh pupae. The adults lay their eggs in the corpse, inhabiting it in the later stages of decay.
