Forensic entomology
Forensic Entomology (pronunciation: /fəˈrɛnsɪk ɛntəˈmɒlədʒi/) is a branch of Entomology that involves the study and application of insects and other arthropods in criminal investigation.
Etymology
The term "Forensic Entomology" is derived from the Latin word "forensis" which means "of or before the forum" and "entomology" which is derived from the Greek words "entomon" (insect) and "logia" (study).
Overview
Forensic Entomology is used in legal cases to determine various aspects of a crime, such as the time of death, location, and whether the body has been moved post-mortem. This is achieved by studying the life cycle of insects, particularly flies and beetles, that colonize the decomposing remains.
Applications
Forensic Entomology has three main sub-disciplines:
- Urban Forensic Entomology - This involves the study of insects in urban environments and their impact on human activities. It can be used in cases of infestation or negligence.
- Stored-product Forensic Entomology - This focuses on insects infesting stored goods, which can be used in cases of consumer complaints or insurance claims.
- Medico-legal Forensic Entomology - This is the most commonly known application, used in connection with crimes and legal cases, particularly those involving homicide.
Related Terms
- Carrion - The decaying flesh of dead animals which is a primary food source for many insects studied in Forensic Entomology.
- Post-mortem interval (PMI) - The time that has elapsed since a person has died. Forensic Entomologists can estimate PMI based on the life cycle of insects found on the body.
- Maggot - The larval stage of a fly, often found on decomposing bodies and used to estimate the PMI.
