Carpenter bees resemble bumblebees in both size and appearance, but are not social insects. They construct their nests in trees or in frame buildings. Most of the top of the abdomen of carpenter bees is without hairs and is shiny black in color. The male bee is unable to sting. It is the male carpenter bee, which is most often noticed. They hover in the vicinity of the nest and will dart after any other flying insect that ventures into their territory,. The female however, is capable of stinging but seldom does. She must be extremely provoked (i.e. handled) before she will sting.

Paper wasps, yellowjackets, and hornets are all masters of papermaking. In spring, the queen constructs a new nest by gathering wood fibers and turning them into a papery pulp, from which she builds a home. Paper wasps build open, umbrella-shaped nests, often found suspended from eaves or window casings on the outside of your home. Hornets are famous for their massive, enclosed nests which can be seen hanging from tree branches or other sturdy perches. Yellowjackets also make enclosed nests, but theirs are found below ground.
