Forensic Entomology

Forensic entomology is the use of insects and their life stages to infer postmortem interval, movement, exposure, and environmental conditions. 121.极简法医鉴识手册：一切犯罪，皆有痕迹 presents blowflies and maggots as one of the relatively useful tools for Forensic Death-Time Inference, while carefully listing their limits.

The source gives a stage logic: eggs, maggots, pupae, and adult flies imply different time windows. It also stresses the complications: flies may not lay eggs at night, winter activity may be low, cold can pause maggot development, and investigators must preserve live larvae and shed cases correctly.

Key Claims

• Insect evidence can be more informative than broad decomposition appearance in some cases.
• Insect stages provide time windows, not exact timestamps.
• Weather, season, light, access to the body, and preservation method can all alter the inference.
• Entomology should be combined with decomposition, stomach contents, pollen, toxicology, and scene evidence.

Connections

• Forensic Death-Time Inference - main inferential use.
• Body Farm Forensic Research - decomposition context.
• Scientific Sampling Discipline - collection and preservation requirements.
• Palynology As Evidence - another biological trace that can support time, place, or environment claims.
