About the Dolichovespula adulterina
Dolichovespula adulterina is a species of parasitic social wasp found in the Palearctic region. D. adulterina feeds on a variety of foods, including insects, spiders, arthropods, meat, molluscs, fruit, nectar, and larval secretions. D. adulterina was formerly considered to be synonymous with D. arctica from the Holarctic region, but more recent research indicates that D. arctica is a separate species.
D. adulterina is one of a few parasitic members the subfamily Vespinae, most species of which are eusocial. The length of the forewing is 13.0–14.0 mm in females and 10.0–12.0 mm in males. Commonly, its body is an ivory colour, but it can be pale yellow on occasion; the pale yellow subspecies are found in the western Nearctic and Palearctic regions. Usually, the clypeus is elongated, but sometimes it will be small and round. Females almost always have a black, disc-like spot, whereas males have a black mark that extends to the ventral margin of the clypeus. Melanic individuals have a black spot extending to the dorsal margin. The postocular band in females is narrower relative to the lateral postocular stripes, whereas in males it is... Wikipedia →
