Field Notes
Description:
The common eastern carpenter bee, Xylocopa virginica, is the carpenter bee most often encountered in the eastern United States. It is often mistaken for a large bumblebee species, as they are similar in size and coloring. They can be important pollinators, especially of open-faced flowers, though they are also known to "rob" nectar by boring holes in the sides of flowers with deep corollas (thus not accomplishing pollination). They sometimes bore holes in wood dwellings and can become minor pests. They use chewed wood bits to form partitions between the cells in the nest.
Habitat:
Carpenter bees are traditionally considered solitary bees, though some species have simple social nests in which mothers and daughters may cohabit. However, even solitary species tend to be gregarious, and often several will nest near each other. It has been occasionally reported that when females cohabit, there may be a division of labor between them, where one female may spend most of her time as a guard within the nest, motionless and near the entrance, while another female spends most of her time foraging for provisions.
Notes:
Nectaring on sedum spectabile.
