What information can be gleaned from the insects found on a corpse?

• A. Victim's age
• B. Time since death
• C. Type of weapon used
• D. Criminal history of the victim

Answer: (B)

The information obtained from the insects found on a corpse is primarily used to estimate the time since death, a process known as forensic entomology. Insects, such as blowflies, are often the first to arrive at a decomposing body, and their life cycles can be relatively predictable under specific environmental conditions. By studying the stages of insect development, including egg, larva, pupa, and adult, forensic entomologists can make informed estimates about how long it has been since death occurred. Factors such as temperature and humidity also play a role in the growth rates of these insects, further refining the estimation of the time since death. Other options, while they might seem relevant in a forensic investigation, do not have a direct correlation with the information insects provide. For instance, the victim's age or the type of weapon used may be determined through separate investigative methods but cannot be deduced from the presence or condition of the insects on the body. Similarly, a victim's criminal history would be unrelated to the insects, which focus solely on the decomposition process and the environmental data surrounding a corpse. This emphasizes the importance of forensic entomology in crime scene investigations, particularly in estimating time since death.
