What is the primary function of a forensic entomologist?

The primary function of a forensic entomologist is to study insects and their development stages to estimate the time of death. This specialization relies on the predictable life cycles of insects, particularly flies, which are often among the first to arrive at a decomposing body. By examining the type and developmental stage of insects found on a corpse, forensic entomologists can provide crucial evidence regarding the post-mortem interval, which is the time that has elapsed since death occurred. This information can be vital in investigations, helping to narrow down timeframes and potentially linking suspects to a crime scene. The scientific principles behind this practice incorporate entomology, ecology, and forensic science, making it a critical component of death investigations where time of death is in question.
