Where does the 'miracle' of metamorphosis of caterpillars to beautiful butterflies have its origin has taunted thinkers since Aristotle. Particularly enigmatic is the origin of the pupa, a transitory stage between the caterpillar and the adult butterfly. The debate is on to this day. One hypothesis sees the caterpillars and other insect larvae as embryos and the pupa as a continuation of their interrupted development. A competing view has it that insect larvae and pupae have evolved to their specialized forms gradually from primitive ancestors, and that their development is continuous. The latter hypothesis, advocated by the author of this review, gains support as we begin to understand how hormones work to navigate insect development.
