Yellowjacket

Common Name: Wasp – Yellowjacket
Latin Name: Vespula
Common Family Name: Vespid wasps
Latin Family Name: Vespidae

Other Names: Paper wasps, meat bees, hornets

Origin:

There are many species of Vespula in North America, including several species introduced from Europe. Two of these, Vespula germanica and Vespula vulgaris, are among the serious scavenger pests in this group.

Biology:

Yellowjackets are social wasps, with a Queen that initiated the colony and female workers that build the nest, care for the young, forage for food, and defend the colony. Colonies typically begin each spring and die off each fall in cooler climates, but may survive over the winter in warmer climates. The population of the colony easily grows to many thousands of workers by the end of the summer, at which time males are produced, mating with new queens takes place, and these fertilized queens then over-winter in protected locations. Adults feed on sweet liquids such as honeydew, nectar, fruit juices, or human foods such as sodas. They also relish a sugary material exuded by the larvae. The larvae are fed meat, and natural sources are insect larvae or bits of flesh from dead animals. As scavengers the workers also gather human foods at outdoor eating areas. The workers are all able to sting repeatedly, and very aggressively defend their colony from perceived intruders. Nests are placed either in aerial locations, including trees, shrubs, wall voids, or attics, as well as in the ground, where workers enlarge holes they find to accommodate the growing colony. The nest is created from cellulose gathered from tree bark, dried plant materials, or other sources, mixed with saliva, and formed as the hexagonal cells for the larvae
