     Note: Among insects belonging to the higher orders, as the
           Hymenoptera, Diptera, Lepidoptera, the pupa is inactive
           and takes no food; in the lower orders it is active and
           takes food, and differs little from the imago except in
           the rudimentary state of the sexual organs, and of the
           wings in those that have wings when adult. The term
           pupa is sometimes applied to other invertebrates in
           analogous stages of development.
