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 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 ]
With their powerful stings and conspicuous warning coloration, often in black and yellow, social wasps are frequent models for Batesian mimicry by non-stinging insects, and are themselves involved in mutually beneficial Müllerian mimicry of other distasteful insects including bees and other wasps. All species of social wasps construct their ...
Because relatedness differs in haplodiploid species, the effects of kin selection are predicted to differ from that of a diploid species. V. pensylvanica is a haplodiploid species. Thus, female offspring have a 0.75 relatedness to their sisters, but only a 0.25 relatedness to their brothers.
Dolichovespula maculata is a species of wasp in the genus Dolichovespula and a member of the eusocial, cosmopolitan family Vespidae.It is taxonomically an aerial yellowjacket but is known by many colloquial names, primarily bald-faced hornet, but also including bald-faced aerial yellowjacket, bald-faced wasp, bald hornet, white-faced hornet, blackjacket, white-tailed hornet, spruce wasp, and ...
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]
To further complicate the issue this only applies to workers. To help with identification, a good practice to observe is to first categorize the wasp as worker, queen, or male before identifying it as V. vulgaris or V. germanica. Gastral pattern (the black dots or marks on the abdomen) are highly variable and not good characteristics to use in ...
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]
