Maggot Mass
Definition
A dense aggregate of larvae feeding collectively, often at body openings or wounds. The mass generates its own heat, sometimes 10 degrees C above ambient, which must be measured directly, not inferred from air temperature.
- Composition
- Larvae feeding collectively as a dense aggregate
- Common sites
- Body openings, wounds
- Heat generated
- Can exceed 10 degrees C above ambient
- Measurement rule
- Measured directly, not inferred from air temperature
Common questions
Why must maggot-mass temperature be measured directly rather than assumed from ambient readings?+
The combined metabolic heat of thousands of larvae can raise the mass's internal temperature well above the surrounding air, so relying on ambient temperature alone in a development-rate calculation would understate larval age.
Where on a body does a maggot mass typically form first?+
Masses tend to form first at natural openings such as the eyes, nose, mouth, and ears, or at open wounds, since these sites offer the easiest access for egg-laying and larval feeding.
