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 ]
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).
Vespula pensylvanica, the western yellowjacket, is a Nearctic species of wasp in the genus Vespula. [1] [2] It is native to regions of North America, largely in areas with northern temperate climates. Its reproductive behavior is constrained by cold weather, which successfully reduces the number of western yellowjackets in cold months.
While most species of this genus inhabit North America, four Vespula species inhabit Europe, namely V. austriaca, V. germanica, V. rufa, and V. vulgaris.; Two common European species, the German wasp (V. germanica) and the common wasp (V. vulgaris), have established in other countries; both species are now found in New Zealand, Australia, and South America, while the former has also been ...
The subfamily Vespinae contains the largest and best-known groups of eusocial wasps, including true hornets (the genus Vespa), and the "yellowjackets" (genera Dolichovespula and Vespula). [1] The remaining genus, Provespa , is a small, poorly known group of nocturnal wasps from Southeast Asia .
Vespula inexpectata Landolt et al., 2010 (Missp.) The eastern yellow jacket or eastern yellowjacket ( Vespula maculifrons ) is a wasp found in eastern North America . [ 1 ] Although most of their nests are subterranean, they are often considered a pest due to their nesting in recreational areas and buildings. [ 2 ]
Vespula germanica workers are known to be opportunistic predators and scavengers. They are efficient at hunting for small, live food sources and at collecting from large stationary sources. [ 9 ] It is believed that the flexibility in V. germanica' s foraging behavior is a key factor in their ability to rapidly colonize new areas in a variety ...
Paravespula is a small subgenus of yellowjacket wasps, including some of the best-known wasp species in the world: the German wasp, Vespula germanica; the eastern yellowjacket Vespula maculifrons; the western yellowjacket Vespula pensylvanica; and the common wasp, Vespula vulgaris.
