Common Eastern Bumble Bee - Bombus impatiens
Not all bees collect pollen, and the ones that do collect it in different ways. For example, leafcutter bees carry pollen on the scopal hairs on their abdomen, some bees in the family Colletidae carry pollen internally, and mining bees carry pollen in their 'armpits'.
Most wild bees do not have pollen baskets. But, honey bees and bumble bees do have pollen baskets (called corbiculae). A corbicula is made up of hairs blended together to form a concave shape. In this photo, you can see one pollen basket on the bee's hindleg.
''Bombus impatiens'', the common eastern bumble bee, is the most commonly encountered bumblebee across much of eastern North America. They can be found in the Eastern temperate forest region of the eastern United States, southern Canada, and the eastern Great Plains.
