Maggot Mass Documentation
Definition
The photographic and physical record of each maggot mass location, volume, instar, and temperature taken at the start of autopsy before any examination disturbs the insects. This is the only record once the pathologist begins.
- Timing
- Start of autopsy, before disturbance
- Recorded details
- Location, volume, instar, temperature
- Why it matters
- Only record before insects are disturbed
- Typically done by
- Forensic entomologist or examiner on scene
Common questions
Why must maggot-mass documentation happen before the pathologist begins examining the body?+
Once autopsy examination starts, the insects are disturbed or removed, permanently changing their distribution, so any location, volume, or temperature data not captured beforehand is lost.
What details in maggot-mass documentation matter most for PMI estimation?+
Instar stage and mass temperature are critical, since development rate depends on both the larval stage reached and the actual thermal environment the larvae experienced, not the scene's ambient temperature.
