Forensic entomology is a branch of applied entomology that uses insects found on corpses or elsewhere around crime scenes in the interest of forensic science. This includes studying the types of insects commonly found on cadavers , their life cycles, their presence in different environments, and how insect assemblages change with decomposition .
Entomological evidence collection is the process of collecting evidence based on insect clues used in criminal investigations.If evidence is not carefully preserved at a crime scene after a death, it may be difficult or impossible for an entomologist to make an accurate identification of specimens, if for example, all morphological characteristics are not preserved.
Forensic entomology also played a role in the investigation of the 1993 raid on David Koresh and the Branch Davidians. [5] Due to the publicity given to these cases, forensic entomology was able to seep further into popular culture. In 2004, the first use of forensic entomology in Brazil demonstrated its importance and potential if executed ...
Forensic entomology deals with the examination of insects in, on and around human remains to assist in determination of time or location of death. It is also possible to determine if the body was moved after death using entomology. Forensic geology deals with trace evidence in the form of soils, minerals and petroleum.
Forensic Entomology is commonly accepted in legal cases and is particularly helpful in determining time of death for both human and wildlife crimes. [2] One of the key insects in these studies are blow flies, which deposit eggs on bodies, and the time off hatching for the eggs can be important for determining time of death. [ 2 ]
The field of forensic entomology is an ever-expanding one. As more case studies are presented and more research is conducted the ability to use insects as determining evidence in cases of abuse or neglect grows. Currently, the use of insects as indicators of abuse or neglect is not a common occurrence.

This article focuses on medico-criminal entomology and how DNA is analyzed with various blood-feeding insects. Forensic entomology can be an important aspect for law enforcement. With the magnitude of information that can be gathered, investigators can more accurately determine time of death, location, how long a body has been in a specific ...
