Western Bumble Bee Larva
Bombus occidentalis (larva)

This grub-like stage develops hidden inside a colony nest, often in an underground cavity such as an abandoned rodent burrow. It feeds on pollen and nectar provisions supplied by adult workers, growing rapidly within waxen brood cells. The larva is soft-bodied, pale, and mostly immobile, relying on the nest chamber for protection. A notable fact is that bumble bee larvae spin silk that later helps form the cocoon used for pupation.
