What is the primary purpose of forensic entomology in investigations?

• A. Blood type analysis of the deceased
• B. Time since death using insect evidence
• C. PMI using insect evidence
• D. Assessing fingerprint patterns

Answer: (C)

Forensic entomology is used to estimate the time since death by studying the insects that colonize a body. Insects such as flies lay eggs that hatch into larvae and go through predictable developmental stages, with the rate of development strongly influenced by temperature. By identifying which species are present, measuring how far they’ve progressed (larvae, pupae, adults), and combining that with past temperature data from the scene, investigators can estimate how long the body has been exposed. This makes estimating the postmortem interval (PMI) using insect evidence the primary purpose. Blood type analysis and fingerprint pattern assessment belong to other forensic disciplines, not entomology, and while the concept of “time since death” overlaps with PMI, the standard framing here is PMI estimation using insect evidence. Keep in mind that indoor conditions or limited insect access can affect precision, so estimates often represent a minimum PMI rather than an exact time.
