2. What is forensic entomology? Forensic entomology is the study of arthropods, especially insects, associated with crimes and other aspects of the courts and judicial system. Forensic entomology usually involves the identification of insects and other arthropods associated with human remains as an aid to determining the time and place of death. Role of insects in forensic science? By studying the insect population and the developing larval stages, forensic scientists can estimate the postmortem index, any change in position of the corpse as well as the cause of death .

3. How can insects be used to determine time of death? An analysis of the oldest stage of insect on the corpse and the temperature of the region in which the body was discovered leads to a day or range of days in which the first insects oviposited or laid eggs on the corpse. This, in turn, leads to a day, or range of days, during which death occurred.

4. Blowflies are often the first insects to colonize a corpse, attracted by the odor of decomposition. Forensic entomologists can analyze the developmental stages of blowfly larvae found on or near the body to estimate the time of death. By determining the age of the larvae and considering environmental factors like temperature, they can provide a fairly accurate estimation of when the individual died.
