Right from the early stages insects are attracted to the decomposing body and may lay eggs in it. By studying the insect population and the developing larval stages, forensic scientists can estimate the postmortem index, any change in position of the corpse as well as the cause of death.
Insects can reveal clues as whether the body was covered, buried, had been outside or indoors, and how hot, cold or humid the weather was. All of these factors affect the infestation of a corpse.
