Funnier than Butterfly

funny word of the day: pupa

From Wikipedia, the free encyclopedia
Pupa of the Cockchafer (Melolontha melolontha)

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.

Pupation may be brief, for example 2 weeks as in monarch butterflies, or the pupa may enter dormancy or diapause until the appropriate season for the adult insect (in temperate climate pupae usually stay dormant during winter, in the tropics pupae usually do so during the dry season). Pupation may last weeks, months or even years. Anise Swallowtails sometimes emerge after years as a chrysalis.
