What is forensic entomology?

• A. The study of insects and other arthropods to estimate time of death by observing the development stages of maggots or insects.
• B. The study of plant tissues to determine origin of soil.
• C. The use of insects to detect drug residues.
• D. The study of human bones in forensic anthropology.

Answer: (A)

Forensic entomology hinges on using insects to help determine the time since death by examining the development of insects found on a body. When death occurs, certain insects—often blowflies—colonize a corpse and progress through predictable life stages: eggs become larvae (maggots), which then pupate and emerge as adults. The rate of this development is strongly influenced by environmental conditions, especially temperature. By identifying the species present and assessing which life stage the insects are in, a forensic entomologist can consult known growth timelines and environmental data to estimate how long the body has been decomposing. This approach is particularly valuable when other PMI indicators are not reliable or have degraded. The other topics described involve plant tissue analysis, drug residue detection, or human skeletal study, which do not address estimating time since death through insect development.
