Rearing Sample
Definition
Live larvae placed in a rearing container with fresh liver or meat, kept at a controlled temperature until adults emerge. Adult morphology allows definitive species identification.

Common questions
Why rear live larvae to adulthood instead of identifying them as larvae at the scene?+
Larval morphology often cannot distinguish closely related species reliably, while adult flies or beetles show diagnostic features such as wing venation or genitalia that allow confident species identification, which in turn determines which development dataset applies.
What happens if the rearing sample dies before reaching adulthood?+
The case then relies on molecular identification methods or on the parallel preserved larval sample collected at the scene, though both carry more uncertainty than a confirmed adult identification.
