This comprehensive guide explores the role of forensic entomology in determining the time of death through insect activity on decomposing bodies. By analyzing the presence of various insect species and their life stages, forensic entomologists can estimate postmortem intervals. Key questions address how entomologists derive time of death, the impact of environmental conditions on decomposition rates, and specific insect associations with decay stages. The guide deepens understanding of the science behind insect involvement in forensic investigations.

Name ________________________________________________ Date _______________ Entomology and Decomposition Questions Use the Time of Death-Entomology notes and the Body Decomposition notes to complete this. What is the main job for the forensic entomologist to do? -______________________________________________________________________________________________________________________ A forensic entomologist at a crime scene determines that the body that was discovered by witnesses was dead for about 20 hours. How exactly might he have figured this out?______________________________________________________________________________________________________________________________________________________________________ A body found in a field has been dead for about 4 days. What EXACTLY would you expect to find on it? ___________________________________________________________________________________ An entomologist finds a mass of adult flies near a body, but also finds 1st instar larva. He determines the body was dead for 9 days. Why didn’t he determine it was only dead for 1.8 days since that is the age of 1st instar larva? ____________________________________________________________________________________________________________________________________________________ Why does the body bloat when you die? _____________________________________________________________________________________________________________________________________ Why do you think flies aren’t attracted to a body in the dry decay stage? ___________________________________________________________________________________________________________ If you found a hide beetle or cheese skipper on a dead body what can you determine about the body?___________________________________________________________________________________ Circle your answer for the following … A body is found on a hot summer day.
