What is a forensic entomologist's primary role?

• A. To conduct autopsies
• B. To study insects to estimate the time of death
• C. To interview witnesses
• D. To analyze trace evidence

Answer: (B)

The primary role of a forensic entomologist is to study insects to estimate the time of death. This field of study leverages the lifecycle of insects, particularly those that are known to infest decomposing remains, such as blowflies and beetles. By examining the species of insects present and their developmental stages, a forensic entomologist can provide valuable insights into the post-mortem interval, which helps law enforcement in understanding when a person may have died. This approach is vital, especially in situations where the time of death cannot be determined through traditional means, such as when remains have decomposed extensively or are discovered long after death has occurred. The expertise of forensic entomologists contributes significantly to homicide investigations, as the timing established through insect evidence can corroborate or contradict other evidence gathered during the investigation. Other roles mentioned, such as conducting autopsies, interviewing witnesses, and analyzing trace evidence, are typically performed by forensic pathologists, detectives, and forensic scientists, respectively, and do not focus specifically on the insect evidence that is crucial to estimating time of death. This delineation of roles reflects the multidisciplinary nature of forensic science, with each expert contributing a unique piece to the investigative puzzle.
