Blowfly pupa on carpet. Coloured scanning electron micrograph (SEM) of a Calliphora vicina blowfly pupa that will hatch an adult fly. A blowfly lays its eggs on dead bodies. This behaviour is studied by forensic entomologists. Eggs generally hatch within 24 hours. A Calliphora larva (maggot) feeds on the decaying flesh for 2-3 weeks. It then moves to a dark place to avoid predation as it pupates. It lies dormant in its pupa,and slowly develops into the adult winged form. A pupa can survive fumigation and other hostile environments. The hatching (by incubation) of pupae found by a dead body can help in estimating the time of death. Magnification unknown | |
