Forensic entomology applies insect biology to legal investigations, using the behavior and life cycles of insects to provide crucial evidence. It is particularly useful in determining the postmortem interval (PMI) when traditional methods fail, identifying whether a body has been moved, and revealing trauma sites on remains. Blow flies, among the first insects to colonize a corpse, lay eggs that hatch into maggots which consume decomposing flesh and aid in nutrient recycling. By analyzing insect growth stages and succession patterns, forensic entomologists can accurately estimate the time since death. Key insect groups studied include Diptera (flies) and Coleoptera (beetles). Forensic entomology also contributes to understanding environmental conditions at crime scenes. In cases involving advanced decomposition or skeletal remains, the emerging field of entomotoxicology helps detect drugs or toxins through analysis of insects feeding on contaminated tissues, expanding the scientific scope of forensic investigations.
