Holometaboly
Definition
Holometaboly is complete insect metamorphosis involving egg, larval, pupal and adult stages. Insects sharing this developmental pattern can still have very different larval anatomy, ecological roles and timing, so one taxon’s identification characters or development schedule cannot be applied universally.
- Context
- Insect development
For example, both beetles and blow flies undergo complete metamorphosis, but their larval anatomy and suitable identification methods can differ substantially.
Taxon and endpoint remain essential.
