What does forensic entomology primarily examine to establish timelines in death investigations?

• A. Faunal succession of insects
• B. Botanical evidence
• C. Soil composition
• D. Weather conditions

Answer: (A)

Forensic entomology primarily examines faunal succession of insects to establish timelines in death investigations. This field studies the insects that are present on decomposing remains to determine the time of death, as different species of insects colonize a body at various stages of decomposition. For example, blowflies are typically among the first insects to arrive at a corpse, laying their eggs shortly after death, while beetles and other insects arrive later as decomposition progresses. By identifying the species of insects present and their life stages, forensic entomologists can estimate how long the individual has been deceased. Botanical evidence, soil composition, and weather conditions, while potentially useful in some forensic contexts, do not provide the same direct biological indicators linked to the timeline of decomposition as the faunal succession of insects does. Therefore, the focus on insect evidence is critical in establishing an accurate timeline for investigations involving death.
