What term describes the sequence in which insects colonize a decomposing body?

• A. Insect Colonization Sequence
• B. Insect Succession
• C. Insect Metamorphosis
• D. Insect Aggregation

Answer: (B)

Insect succession describes the orderly, time-dependent sequence of species that colonize a decomposing body. In forensic entomology, this concept captures how different insect communities arrive and are replaced as decomposition progresses. Early colonizers, such as blowflies, quickly discover the body and lay eggs that hatch into larvae, while later on, other insects like certain beetles move in as the tissue changes and resources become available or unfavorable conditions arise. This predictable pattern under similar environmental conditions helps estimate the postmortem interval. The other ideas refer to different concepts: metamorphosis is about developmental life stages, aggregation is about insects clustering together, and while a phrase like insect colonization sequence could describe the idea, the established term used in practice is insect succession.
