The examination of insects in, on, and around human remains to assist in determining the time or location of death.

Medicolegal forensic entomology includes arthropod involvement (mostly necrophagous or corpse-eating) involving events such as murder, suicide and rape, but also includes physical abuse and contraband trafficking.

In murder investigations, it is concerned with where and when insects lay eggs; and in what order they appear in dead bodies. This can be helpful in determining the time or post mortem interval and location of the death being investigated.
