Abstract

MASCIOCCHI, Maité; BEGGS, Jacqueline R.; CARPENTER, James M.  and  CORLEY, Juan C.. First record of Vespula vulgaris (Hymenoptera: Vespidae) in Argentina. Rev. Soc. Entomol. Argent. [online]. 2010, vol.69, n.3-4, pp.267-270. ISSN 0373-5680.

Vespula vulgaris (Linnaeus) is a social vespid native to the Holarctic region. The first detection of this species in Argentina is here reported. Workers were captured close to San Carlos de Bariloche (Argentina) during February 2010, while sampling for another successful invader, the German wasp or Yellowjacket, Vespula germanica (Fabricius). Both these wasp species are very similar morphologically and share a number of common habits. Also, some identification features and biological characters are here explained.

Keywords : Vespula germanica; Invasive social insects; Exotic species; New record.
