Larva

Information about Larva

The caterpillar of Proserpinus proserpina, an insect larva

A larva (Latin; plural larvae) is a juvenile form of animal with indirect development, undergoing metamorphosis (for example, insects or amphibians).

The larva can look completely different from the adult form, for example, a caterpillar differs from a butterfly. Larvae often have special (larval) organs which do not occur in the adult form. The larvae of some species can become pubescent and not further develop into the adult form (for example, in some newts). This is called neoteny.

It is a misunderstanding that the larval form always reflects the group's evolutionary history. It could be the case, but often the larval stage has evolved secondarily, as in insects. In these cases the larval form might differ more from the group's common origin than the adult form.

The early life stages of most fish species are considerably different from juveniles and adults of their species and are called larvae.

Names of various kinds of larvae:

Animal	Name of larvae
Hydrozoa	planula
Freshwater mussels	glochidium
Many crustaceans	nauplius
Decapoda	zoea
Butterflies and moths	caterpillar
Beetles	grub or Scarabaeoidea, triangulin
Flies	maggot
Mosquitos	wiggler
Bees	schadon
Fish (generally)	larva
Lamprey	ammocoete
Eels	leptocephalus
Amphibians	tadpole, polliwog
Certain Mollusca, annelids	trochophore
Dragonflies and Grasshoppers	nymph

A pubescent person is a young individual who is undergoing the physical and mental changes associated with puberty.
