Forensic entomology is using insect biology to determine specific aspects of a crime. It can be used to determine time of death‚ whether or not a body has been moved‚ and also if the victim had been intoxicated with any substances. Insects are also prime examples of Locard’s principle when solving a crime. The history of forensic entomology dates back to as early as the thirteenth century‚ and is still been developed today.

Forensic entomology is a very interesting field. It is incredible how they can determine the time of death. They literally wait for maggots to grow larger so they can be easily identified. An entomologist can even use bugs to determine if the person was on drugs before or after he or she died. The other stages other than the fresh stage that you stated are called the bloated stage‚ the decay stage‚ the post-decay stage and the dry stage (“Forensic Entomology‚” n.d.).
