Emergence Record
Definition
Documented observations of adults leaving their puparia or pupal coverings. Record inspections, observed development and environmental conditions. If a covering is intact at one inspection and empty at the next, emergence occurred within that interval.
- Context
- Rearing records
For example, a case intact at one inspection and empty at the next supports an emergence interval rather than the exact second inspection time.
Do not assign the second inspection’s exact time to an unobserved event. The interval can contribute uncertainty to a developmental calculation.
