Insects colonize cadavers in a predictable sequence, also known as insect succession. The first to arrive are the necrophagous species, drawn by the strong scent of decomposition. Blow flies can invade a corpse within minutes of death, and flesh flies follow close behind. Soon after come the dermestid beetles, the same beetles used by taxidermists to clean skulls of their flesh. More flies gather, including house flies. Predatory and parasitic insects arrive to feed on the maggots and beetle larvae. Eventually, as the corpse dries, hide beetles and clothes moths find the remains.
