Instar synonyms

Young resembling parents, but penultimate instar passive and enclosed in a filmy pellicle.

The new instar - or temporary form - is often very different from the old one, and this is the essential fact of metamorphosis.

But examples are not wanting of a more or less complete resting habit during the latest nymphal instar.

Young animals always unlike parents, the wing-rudiments developing beneath the larval cuticle and only appearing in a penultimate pupal instar, which takes no food and is usually passive.
