Viewed from the front, Dolichovespula faces are long, while Vespula faces are short and round.

The species is not regarded as being threatened, although in common with other social wasps, it appears to have declined markedly in the late 1990s and early 2000s. The oculomalar space, the distance between the eye and the mandible, is long in Dolichovespula and short in Vespula. Variation. There are no records of other flowers being visited by this species, except for the Apiaceae mentioned above. Waray hini subspecies nga nakalista. An Dolichovespula norwegica in nahilalakip ha genus nga Dolichovespula, ngan familia nga Vespidae. Metasomal terga 1 and 2 with ferruginous blotches laterally in worker and male, these occasionally absent, especially on tergum 1. At the end of the season, in August, new males and females (queens) are produced. often nest underground. Dolichovespula is a small genus of social wasps distributed widely throughout the Northern Hemisphere. In addition, there is one social parasite, Dolichovespula adulterina, whose queens take over established nests of D. norwegica in much the same way as Vespula austriaca takes over nests of Vespula rufa in Britain (see Edwards (1998) p. 64). obs.). Spring queens are on the wing from mid-April to early June; workers from July to mid-October, and the newly emerged sexuals from September to October (Edwards 1980). Fore wing length 9.0–10.0 mm (workers), 12.5–13.0 mm (♀♀), 10.5–12.5 mm (♂♂). Description and notes. Dolichovespula is a small genus of social wasps distributed widely throughout the Northern Hemisphere. Except for the colour of its pale markings the species is very similar to D. norvegicoides, from which it can be separated by the characters provided in the key. Palaearctic: northern and western Europe east to Kamchatka and northern China, south to Turkey and Kirghizia (Carpenter and Kojima 1997, Archer 1999).

Identification keys and details of biology are given in Archer (1996), Else (1994), Edwards (1980) and Spradbery (1973).
The yellow and black members of the genus are known by the common name yellowjackets in North America, such as Dolichovespula norwegica, along with members of their sister genus Vespula. CJAI 05, February 19, 2008doi: 10.3752/cjai.2008.05, Matthias Buck, Stephen A. Marshall, and David K.B. Archer, Michael E. (September 2006). Overseas, occurs across most of northern Europe and Asia where it may be found as far north as 70°N.

Description It is a very close relative of Dolichovespula norwegica but lacks the pair of red spots on the second gastral tergum (but note, these markings are also absent in some specimens of Dolichovespula norwegica). Dolichovespula norwegica (Fabricius, 1781) Disclaimer: The Animal Diversity Web is an educational resource written largely by and for college students.ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. Species recognition. Nests are abandoned and soon break up and rot away. Dolichovespula is a small genus of social wasps distributed widely throughout the Northern Hemisphere. Poorly known in the Nearctic. A set of morphological differences distinguishes them from Vespula. The males spend most of their time feeding on the same umbels, and on bramble and other late fruits. Can be found in most areas, but tends to prefer nesting adjacent to heathland and moorland in Britain (pers. Except for the colour of its pale markings the species is very similar to D. norvegicoides, from which it can be separated by the characters provided in the key. This is the only ivory-marked species of Dolichovespulain which the apical fasciae of terga 1 and 2 are neither interrupted nor incised. This is one of the three British ‘long-cheeked’ social wasps. Scutellum in female rarely, in male often without ivory spots; metanotum almost always lacking ivory spots. In a study on the nesting biology of Dolichovespula, a colony of D. maculata with 771 workers was reported as having the largest recorded population count.
The yellow and black members of the genus are known by the common name yellowjackets in North America, such as Dolichovespula norwegica, along with members of their sister genus Vespula. However, it is rare in southern Europe, where it tends to be an alpine species (in the Pyrenees, for example). Biology. In Europe nests are often found in low shrubbery, less commonly in trees (sometimes more than 10 m above ground), haystacks, beehives, old bird nests, and window frames (Spradbery 1973). Dolichovespula nests are usually aerial, while Vespula spp.
