Yellowjacket or yellow-jacket is the
common name in
North America for predatory
wasps of the
genera Vespula and
Dolichovespula. Members of these genera are known simply as "wasps" in other
English-speaking countries. Most of these are black-and-yellow; some are black-and-white (such as the
bald-faced hornet, Dolichovespula maculata), while others may have the
abdomen background color red instead of black. They can be identified by their distinctive markings, small size (similar to or slightly smaller or larger than a
honey bee), their occurrence only in colonies, and a characteristic, rapid, side to side flight pattern prior to landing. They are often mistakenly called "bees"
[1]. All females are capable of
stinging. Yellowjackets are important predators of pest insects.
