Bombus impatiens (Common Eastern Bumble Bee)
The bumble bees and the carpenter bees look a bit alike, both being fairly large and a combination of black and yellow or orange. The bumble bees are in a separate subfamily from the carpenter bees, being in the subfamily Apinae along with the honey, Long-horned, Orchid, and Digger Bees. This one is considerably smaller than the carpenter bee I posted a photo of recently, probably being at most about two centimeters long.
