Bumble Bee

Bumble bees (Bombus spp.) belong to the family Apidae, order Hymenoptera, and are characterized by their robust, hairy bodies, often striped with black and yellow or orange. Queens are typically larger than workers and males. Their lifecycle is annual, beginning with a queen emerging from hibernation in spring to establish a nest and lay eggs. Larvae develop through several instars within wax cells, pupating before emerging as adult workers. Reproduction involves the queen producing both fertile eggs (females/workers/new queens) and unfertilized eggs (males); new queens and males emerge later in the season to mate, perpetuating the species. Bumble bee colonies are much smaller than honey bee colonies, usually numbering in the hundreds, and they exhibit moderate cold tolerance due to their thermoregulatory capabilities, including shivering to warm up.

Bumble bees are primarily diurnal, actively foraging for nectar and pollen during daylight hours, although some species may extend activity into twilight. They exhibit a form of social structure, with a queen, sterile female workers, and male drones, but their social organization is less complex than that of honey bees; workers share foraging duties and nest maintenance. Communication within the colony mainly involves chemical cues for nest protection and location of resources, along with tactile interactions. Their feeding habits are essential for pollination, as they collect nectar for energy and pollen as a protein source for larval development. Public health impact is generally low; stings are painful but typically not life-threatening unless an individual is allergic, and structural impact is negligible as they do not consume wood or damage buildings.
