A review of mites associated to carcasses and corpses is done. Host-insect species and their phoretic mites are studied, as well as the importance of phoretic mites as markers of time of death. Since 2006, and thanks to funding from the Leverhulme Trust, a group of researchers at UK Universities undertook a revival and expansion of the pioneering efforts of Mégnin. New research, plus evidence from crime cases, is demonstrating that mites can be as relevant as the insects that carry them to a corpse or to/from a crime scene.
