Carpenter bees are large insects bearing a striking resemblance to bumblebees. Roughly 1/2-inch to 1-inch long, the bees can be distinguished by shiny, as opposed to hairy, abdomens. In general, coloring is blue-black and yellow or black and orange.
Carpenter bees spend much of their lives traveling from their nest to obtain food from nearby flowers. As such, the bees can be hard to spot and are more likely to be identified by their distinctive humming sound and nesting holes.
