Bumble Bees are the round, fuzzy, black and yellow (sometimes with orange or red) bees that you find buzzing among your flowers during the fresh days of spring, lazy days of summer, or golden days of autumn. They differ from other bees by living in colonies with a queen, drones (males) and workers. Efficient pollinators, they vibrate their muscles vigorously to shake pollen loose from flowers in a technique called "buzz pollination". They are also out foraging for food in conditions when other insects are resting, such as the lower light of early morning and early evening, in cooler temperatures, and even light rain.
