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"[LINK: http://www.livingwithbugs.com/PDFiles/yj_bee.pdf] [1]. All females are capable of stinging. Yellowjackets are important predators of pest insects.Akre, R.D. et al. (1980) The yellowjackets
