What is juvenile hormone?Is there a difference between pupa and cocoon? If yes, what is the difference?
Question Date: 2014-05-16
Answer 1:

A pupa is a life cycle stage of a group of insects (including flies, beetles, wasps, bees, ants, butterflies, moths, and several other groups) where the insect goes into an inert phase between a juvenile life stage and an adult life stage. A cocoon is essentially a pupa made out of or encased in silk, which is a substance made by caterpillars (the larvae of butterflies and moths).
