Instars sentence example
- Larva campodeiform, usually feeding by suction (exceptionally hypermetamorphic with subsequent eruciform instars).
- For in the post-embryonic development of the ancestors of the Endopterygota we may imagine two or three instars with wing-rudiments to have existed, the last represented by the sub-imago of the may-flies.
- There are usually 7 to 8 larval instars, but the number may vary from 5 to 16.
- Further, although the wing-rudiments appear externally in an early instar of an exopterygotous insect, the earliest instars are wingless and wing-rudiments have been previously developing beneath the cuticle, growing however outwards, not inwards as in the larva of an endopterygote.
