Forensics

Some insects, particularly blowflies and their larvae, feed on carrion (decaying flesh) and they are quick to discover dead bodies – including those of humans. This makes them useful to police departments investigating murder cases, because the size and number of the flies gives a good indication of how much time has passed since death.

Museum scientists are often consulted and have been involved in over 120 criminal cases. Here is some more information about the species of insect they study to help them work out the circumstances of a suspicious death.
