Which method studies the predictable sequence of insects attracted to a decomposing body?

• A. Insect Development
• B. Entomotoxicology
• C. Successional Ecology
• D. Temperature analysis

Answer: (C)

Successional Ecology focuses on how insect communities arrive and change in a predictable order as a body decomposes, providing a timeline that helps estimate time since death. The idea is that decomposition creates distinct ecological niches over time, so different species tend to appear, increase, or fade at particular stages. This predictable sequence—early colonizers arriving soon after death and later species taking over as the remains change—forms a used-for-PMI pattern in forensic investigations. Insect Development looks at how individual insects progress through life stages and how long those stages take, which helps age larvae or pupae to refine PMI, but it doesn’t map the overall sequence of insect arrivals. Entomotoxicology uses insects to detect toxins in a body, not the succession of colonizing species. Temperature analysis uses environmental conditions to adjust development rates, again focusing on timing of development rather than the order of species’ appearance.
