In the case of insects with complete metamorphosis (larva looks very different from the adult (caterpillar/butterfly) and the insect pupates) it's simply called a larva. In the case of incomplete metamorphosis (larva is a small wingless version of the adult, doesn't pupate but molts into final form) it's called a nymph, unless the larval stage is aquatic, like in dragon/damsel/mayflies and others, then it's called a naiad. Aquatic larvae of insects with complete metamorphosis such as mosquitos are still called larvae.
This is called a pupa (or sometimes a chrysalis)
The insect at this stage is likely a newly-hatched larva or caterpillar. It will undergo various stages of development before transforming into its adult form. It is important to identify the specific species to better understand its life cycle and habits.
