The insects present at crime scenes can provide vital information about the crime. 

All forensic entomology investigations begin by establishing the identity of the insects, a role that the Museum and its staff are uniquely suited to.

The Museum's forensic entomologists analyse the insects found at a variety of crime scenes every year, providing evidence based on the findings.

Suspicious deaths

Forensic entomologists at the Museum are involved in several death investigations each year collecting and analysing insect samples from crime scenes.

These insects can provide crucial evidence about cases at any time of the year

  • Estimating minimum post-mortem interval, even in cases of severe burning
  • Determining if the body has been moved since death
  • Determining how long a buried body was exposed above ground before burial

In addition to death enquiries, forensic entomology can be applied to any situation where insects have been collected as evidence.

For example

  • determining the origin of plant material (e.g. cannabis) by a knowledge of the distribution of insects found on the plants
  • assessing how long wild or domestic animals have been infested by insects, either infested when alive in cases of cruelty and neglect, or when dead in cases of illegal disposal of remains
