About this mock
This mock test covers the core mechanisms of insect-based death investigation, from the biology of carrion beetles and blow flies to the staged decomposition ecology that underpins postmortem interval estimation. Questions draw on the five recognised decomposition stages, the succession of insect waves across them, the temperature-dependent blow fly life cycle, and the analytical principles behind both the developmental and successional PMI methods.
This test is designed for students, MSc and BSc learners, and practitioners of forensic entomology who need to move beyond species identification into the applied mechanics of casework. It suits candidates preparing for graduate assessments and professional development in medicolegal death investigation, and practitioners seeking a structured review of foundational entomological PMI science.
Topics covered:
- Carrion beetles and their role in late decomposition
- Mites, moths, and non-fly arthropods in casework
- The five decomposition stages and their chemical ecology
- Insect succession waves and community turnover
- Blow fly egg-to-adult developmental timeline
- Larval instars and the post-feeding dispersal stage
- The minimum postmortem interval and its distinction from true PMI
- Accumulated degree days and the developmental threshold
Questions are set at medium difficulty, using near-neighbour distractors drawn from closely related species, adjacent stages, and overlapping genera.
Allow 30 minutes.
