Differentiate between larva of silkworm and larva of bee

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 in stars.

The bee larva is a legless and featureless white grub. It is specialized to eat and never leaves the individual wax cell.
