BIOLOGY

Honey bees form very large colonies in large enclosed spaces (typically the hollows of trees). They construct characteristic hexagonal combs in which they rear their larvae and store honey and pollen. New honey bee colonies are formed by swarms consisting of a mature queen and hundreds of workers.
Bumble Bees form moderately sized colonies in preexisting cavities in the ground (commonly, abandoned rodent burrows). New bumble bee colonies are founded by a single inseminated queen in early spring.
