Yellowjacket , “Meat Bee”
Vespula spp., Dolichovespula spp.
A meat bee is not a bee at all, but a wasp from either the Vespula or Dolichovespula genus. Meat bees are also known as “yellowjackets,” especially in the United States.

Class:
Insecta
Order: Hymenoptera
Family: VespidaeSize:Yellowjacket adult workers are 3/8-5/8 in (10-16 mm) long, depending on species; queens are 25% longer.Characteristics: Wings are folded lengthwise when the yellowjacket is at rest.Color: Abdomen usually has yellow and black bands, but some species are white and black, and two northern species have red markings.Where found: All around the world; 16 species in the United StatesComparison with other species: Baldfaced hornet is mostly black, with light markings mostly on face but also on thorax and end of abdomen. European hornets are large, to 1 3/8 in, and are brownish with orange bands. Honey bee has hairy eyes, and its abdomen is not banded with yellow and black. Some clear-wing moths look like yellowjackets, but have mouths that are siphons.

Nest: A paper-carton nest which eventually has 30-55 compartments surrounded by a paper “envelope”. It is made of chewed cellulose by a queen who has overwintered and is ready to lay her eggs, one in each compartment. Eventually there will be a number of paper-like combs attached one below the other, and covered with many layers of “paper”.

Food: Insects and nectar.

Biology: Yellowjackets are social insects that live in colonies. Each colony has a queen that lays the eggs, female workers that do not reproduce, and males that come forth in late summer, being reared in the same cells that were earlier used for the workers. Larger cells for rearing queens are built at the end of the season. Mating occurs in fall after newly emerged queens and males leave the nest. Only queens who have mated hibernate and live through the winter. The past season’s queen who built the nest, as well as the workers and the males, all die.

Damage: Yellowjackets are beneficial as they eat many pest species. They may sting when the nest entrance is approached, and can be aggressive, stinging several times.

Invasion: Depending on the species, nests may be built on the ground, or in shrubs, trees, or buildings, such as houses, garages, and sheds.
