Forensic Entomology
Definition
The application of insect biology to legal investigations, most commonly using the developmental stage and species of insects colonising human remains to estimate the minimum post-mortem interval.
- Primary use
- Estimating post-mortem interval from insect colonization patterns
- Scope
- Death scenes, neglect cases, food safety, urban and structural investigations
Common questions
How do insects help estimate when someone died?+
Forensic entomologists examine which insect species are present on human remains and what stage of their life cycle they are in. Since insects develop at predictable rates based on temperature, this information helps estimate the minimum time since death.
What insects are used in forensic investigations?+
Various insects and arthropods colonize human remains. Forensic entomologists identify these species and their developmental stages to answer legal questions. The specific insects involved depend on local geography, climate, and death-scene conditions.
Is forensic entomology only used in death investigations?+
No. Forensic entomology also applies to neglect cases involving living people, food law violations where insects contaminate products, and urban or structural issues where insects cause damage.
