III) PUPA:
It is the resting and inactive stage in all holometabolous insects. During this stage,
the insect is incapable of feeding and is quiescent. During this transitional stage, the larval
characters are destroyed and new adult characters are created. There are three main types of
pupae.
1) OBTECT:
Various appendages of the pupa viz., antennae, legs and wings pads are glued to
the body by a secretion produced during the last larval moult. Exposed surface of the
appendages are more heavily sclerotised than those adjacent to body. Eg: moth pupa.
