Answer 1

Silkworms go through four stages of development, as do most insects: egg, larva, pupa and adult. The adult (imago) stage is the silkworm moth. The larva is the caterpillar (not really a "worm" at all). The pupa is what the silkworm changes into after spinning its cocoon before emerging as a moth. Since the silkworm grows so much, it must shed its skin four times while it is growing. These stages-within-a-stage are called instars.
