In which field would a forensic entomologist analyze insect evidence?

A forensic entomologist specializes in the study of insects to help solve criminal cases, often focusing on the role that insects play in the decomposition of human remains. This analysis can provide critical information, such as the time of death, which is essential in crime scene investigations. By examining the type and stage of development of insects found on a body, forensic entomologists can determine how long a body has been exposed, which aids investigators in reconstructing the timeline of events surrounding a crime.

In contrast, the other fields listed are not directly related to insect analysis. Toxicology involves studying the effects of drugs and poisons, ballistics deals with firearms and ammunition analysis, and psychology focuses on understanding human behavior and mental processes. While each of these fields plays an important role in forensic science, they do not specifically involve the analysis of insect evidence as part of their investigative processes.
