Pupa
A pupa (Latin pupa for doll, pl: pupae or pupas) is the life stage of some insects undergoing transformation. The pupal stage is found only in holometabolous insects, those that undergo a complete metamorphosis, going through four life stages: embryo, larva, pupa and imago. (For a list of such insects see Holometabolism).
The pupae of different groups of insects have different names such as chrysalis for the pupae of butterflies and tumbler for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests or shells.
Position in life cycle
In the life of an insect the pupal stage follows the larval stage and precedes adulthood (imago). It is during the time of pupation that the adult structures of the insect are formed while the larval structures are broken down. Pupae are inactive, and usually sessile (not able to move about). However, the pupae may be exarate (have movable legs, wings, antennae, etc.) or obtect (covered in a hard case with the legs and wings attached immovably against the body). They have a hard protective coating and often use camouflage to evade potential predators.
Pupa (gastropod)
Pupa is a genus of small sea snails, marine gastropod molluscs in the family Acteonidae.

Pupa (manga)
Pupa (Japanese: ピューパ Hepburn: Pyūpa) is a 2011–2013 Japanese horror manga series written and illustrated by Sayaka Mogi. An anime television series adaptation produced by Studio Deen premiered on January 9, 2014.
Plot
The story of Pupa is about two teenagers, Utsutsu and his little sister Yume. Their father was an extremely abusive man, beating their mother and then his children after he was fired. After a divorce, their mother began dating another man, and the father left the two kids alone. Now orphaned, Utsutsu promised himself that he would always protect Yume.
After seeing red butterflies, these two siblings become infected with a virus known as Pupa. This virus mutates organisms into insatiable monsters, only seeking to feed on any sort of life. Yume succumbs to the full effects of the Pupa virus, but reverts into a human. Utsutsu, instead of turning into a monster, gains regenerative powers. In order for the virus to be suppressed in Yume, Utsutsu must take a drug and have Yume feed on his flesh.
