No larval stage is the maggot (as in housefly) then they pupate and the adult emerges after metamorphosis. Those insects where the nymphs adults look like adults have only a 3-stage cycle egg, nymph, adult, with no larval or pupal stage.
Hemimetabolous insects have a gradual change from larva to adult and the larva resembles the adult it will become. Holometabgolous insects have a pupal instar and the larva does not resemble the adult.

A caterpillar is in the Larva stage. When it goes into it's cocoon it will be in the pupa stage. When it hatches, it will become a butterfly (and therefore be in the adult stage)
The ant goes from egg to larva, small larva to larger larva, larva to pupa, pupa to adult. The pupa to adult stage is considered the metamorphosis.
Axolotols do not really skip the larva stage. But when they hatch, they are a larva and they do not metamorphose into an adult. They stay that phase all their life.
I think it is metamorphosis
Pupa
both in larva stage
When the butterfly is at a larvae stage it starts to eat leaves, but they eat milkweed plants to protect themselves from predators. Then later they start make a pupa to grow into a butterfly.
Concerning the life cycle of insects, the larva stage comes before the pupa stage. The pupa stage is followed by adulthood.
