What is the role of blowflies in forensic entomology?

• A. They are the most common and important insects for estimating time of death.
• B. Moths are the most common and important insects for estimating time of death.
• C. Beetles are the most common and important insects for estimating time of death.
• D. Ants are the most common and important insects for estimating time of death.

Answer: (A)

Blowflies are the first insects to reach a recently deceased body, attracted by odors and warmth. Their eggs hatch into maggots that go through predictable, temperature-dependent developmental stages. By matching the maggot age and size to published growth rates or accumulated degree days, forensic scientists estimate how long the body has been exposed—the postmortem interval. Because blowflies colonize quickly and have extensive, well-characterized development data, they provide one of the most reliable means for estimating time of death. Other insects like moths, beetles, and ants tend to arrive later as decomposition advances, so they’re less useful for early PMI estimation, though they can add information later in the timeline.
