Face of a southern yellowjacket (Vespula squamosa)Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula.A typical yellowjacket worker is about 12 mm (0.47 in) long, with alternating bands on the abdomen; the queen is larger, about 19 mm (0.75 in) long (the different patterns on their abdomens help separate various species).
A single queen initiates a nest in the spring by constructing an embryonic nest, which contains a series of hexagonal cells. These cells are used to house one wasp through the immature stages of life: egg, larval instar, and pupa. The colony grows rapidly during the summer with a huge increase in worker numbers and nest size.
Vespula squamosa, or the southern yellowjacket, is a social wasp.This species can be identified by its distinctive black and yellow patterning and orange queen. [1] This species is typically found in eastern North America, and its territory extends as far south as Central America. [1]
But social wasps, which live in a colony with a queen, can become a problem when their nests are situated to close to your living areas. ... Ground wasps, or yellowjackets, are about ½-inch long ...
Many wasp lineages, including those in the families Vespidae, Crabronidae, Sphecidae, and Pompilidae, attack and sting prey items that they use as food for their larvae; while Vespidae usually macerate their prey and feed the resulting bits directly to their brood, most predatory wasps paralyze their prey and lay eggs directly upon the bodies ...
After emerging from the diapause when winter ends, the fertilized queen searches for a nest site. When it is located, a small nest is formed. The queen continues to forage for construction materials and food until four to seven workers have emerged. At this point, the queen focuses solely on laying eggs and the nest continues to expand.
Palaeovespa florissantia, late Eocene. The Vespidae are a large (nearly 5000 species), diverse, cosmopolitan family of wasps, including nearly all the known eusocial wasps (such as Polistes fuscatus, Vespa orientalis, and Vespula germanica) and many solitary wasps. [1]
A queen initiates a colony in the spring by choosing a site and building a small paper nest where it lays its eggs. Then, the eggs hatch from the brood cell and the queen feeds the larvae. [8] These larvae eventually become workers and the colony continues to grow and peaks in the summer. [8] The workers are morphologically distinct from the queen.
