These insects do not feed directly on the decomposing remains or its fluids, but are considered to be the second most forensically important ecological role. [ 3 ] [ 7 ] Predators of necrophagous insects include species from the Coleoptera families Silphidae (carrion beetles) and Staphylinidae (rove beetles). [ 3 ]
Forensic entomology is a branch of applied entomology that uses insects found on corpses or elsewhere around crime scenes in the interest of forensic science.This includes studying the types of insects commonly found on cadavers, their life cycles, their presence in different environments, and how insect assemblages change with decomposition.
Forensic entomological decomposition is how insects decompose and what that means for timing and information in criminal investigations.Medicolegal entomology is a branch of forensic entomology that applies the study of insects to criminal investigations, and is commonly used in death investigations for estimating the post-mortem interval (PMI).
Necrophages are useful for other purposes too. In healthcare, green bottle fly larvae are sometimes used to remove necrotic (dead) tissue from non-healing wounds, [10] [11] and in waste management, black soldier fly larvae are used to convert decomposing organic waste into animal feed.
The fly larvae digest part of the carcass, and the beetle larvae will consume the parts that the fly larvae did not, which typically consists of flesh left on the bones and on the moist inside of the face. [5] Eventually the larvae will fall to the ground, dig into the dirt, and pupate. Adults practice overwintering. [2] [3]
Silphidae larvae are opportunistic predators that will feed on dipteran eggs, larvae, and on the carcass itself. [20] This presents a problem in the determination of post-mortem interval because Silphidae are known to eradicate other species from carrion. By eliminating the first colonizing species Silphidae can give an incorrect post-mortem ...
The larvae typically hatch 5–7 days later. Both the female and male have important roles as their larvae mature. Preservation of the carcass, protecting the larvae from predators and feeding the larvae are all roles taken on by the adults. The males then disperse from the carcass once the larvae have reached the final instar. The females will ...
The main exception is in those species whose larvae are not fully sclerotized, mainly some holometabola; but even most unsclerotized or weakly sclerotized larvae tend to have well-sclerotized head capsules, for example, the larvae of Coleoptera and Hymenoptera. The larvae of Cyclorrhapha however, tend to have hardly any head capsule at all.
