Nymphs & Larvae
The juveniles of most insects look very different to the adults. Whilst it is difficult to recognise the species when looking at nymphs and larvae, there are many where it is possible and these are displayed here.
The term 'nymphs' refers to juveniles of species that go through incomplete metamorphosis, that is each nymph stage (instars) looks a little like a small version of the adult. The term 'larvae' is used for species that undergo complete metamorphosis where the juvenile is very different to the adult and goes through a major transformation in the final change to an adult (for example caterpillars and butterflies).
Nb. There is a separate gallery for caterpillars of butterflies, moths and sawflies.
