Median wasp
The median wasp (''Dolichovespula media'') is a species of social wasp of the family Vespidae found throughout Europe and Asia. It builds aerial paper nests often in shrubs or trees, and occasionally under the eaves of buildings. It is most common to see this wasp between May and October during its 3.3 month colony cycle.〔〔(【引用サイトリンク】url=http://www.naturespot.org.uk/species/median-wasp )〕 Behaviors of this wasp include nest defense, curling which is believed to function in brood incubation, and gastral vibration which is involved in larval feeding.〔 The median wasp has a halplodiploid sex determination system that results in a high level of relatedness within the colony.〔 This species is not usually aggressive but will sting if they feel their nest is threatened. Most foraging in the nest is done by the workers once the first ones reach adulthood. These workers forage for insects, nectar, and wood for nest construction in temperatures as low as .〔 The median wasp is known to be occasionally affected by the fungus ''Cordyceps sphecocephala'' and the Cricket paralysis virus. 〔
==Taxonomy and phylogeny==
The median wasp was first classified by Anders Jahan Retzius in 1783. It is part of the genus ''Dolichovespula'', a small genus of only 18 social wasp species including species such as the tree wasp (''D. sylvestris''), the Saxon wasp (''D. saxonica''), and the parasitic hornet (''D. adulterina''). This wasp is part of the subfamily Vespinae which include social wasps, social hornets, and yellow jackets.〔
