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).
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. Between August and September, males and queens are produced, which then leave the nest and mate.
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]
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.
The benefits are gained through various measures, such as increasing colony efficiency and establishing a female-based sex-allocation ratio. Worker policing is especially common in colonies where queens mate with multiple males. Thus on average, the workers are more closely related to sons of the queen than to those of other workers.
Rescuers in Yellowstone National Park searched the area of Eagle Peak on Sunday in an effort to find a park concession worker who failed to check in at the end of a personal trip, authorities said.
The most commonly known wasps, such as yellowjackets and hornets, are in the family Vespidae and are eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each ...
