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).
This yellow jacket is a social insect, living in colonies of hundreds to thousands of individuals. [3] Along with their subfamily, Vespinae , this species demonstrates supportive parental care for offspring, separation of reproductive and sterile castes , and overlapping generations. [ 4 ]
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]
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 ...
D. arenaria can be identified by the medially interrupted or incised apical fasciae of terga 1 and 2. [6] They are yellow in color and can be differentiated from the other yellow-colored wasps, such as D. adulterina, in its genus by the lack of black markings in the ocular sinus. [6]
The Summary. Flooding in North Carolina following Hurricane Helene has led to swarms of yellow jackets. Heavy rain and standing water likely destroyed the insects' nests underground and in trees.
The types of arthropods in the diet depend on the habitat. In Hawaii, V. pensylvanica causes the direct reduction of Hylaeus species due to predation. Three species in particular are found in the diet, including H. difficilis, H. laetus, and H. nivicola. The Hylaeus species are typically killed under cool conditions while warming up in the sun ...
