There are a number of species of wasps with bold designs of black or dark brown and yellow or black and white which go by the names of hornets or yellowjackets. They are narrow waisted strong fliers that fold their wings when in repose.
There are several species of these wasps and the pattern varies depending on the species, but they generally present stripes. They are about half an inch in size or longer. They are feared for their painful sting, although they are not prone to attacking when at flowers. They build large nests, with a queen and many female workers and also some males.
Some build their nests underground (terrestrial), others hanging from tree branches or inside a tree hole (aerial) and still others build either aerial of terrestrial nests, depending on the circumstances. They are defensive of their nests and that is when they can be dangerous. They hunt insects to feed the young and also visit flowers for the nectar that fuels their flight. Some are lesser pollinators.
