Explanation of Names
Author: Lepeletier de Saint Fargeau and Brullé, 1835
Identification
Differs from all North American species by the unusual colour pattern (metasoma richly marked with yellow but spots on tergum 2 much smaller than on following terga; tergum 1 with yellow sides) and the unusually slender first metasomal segment (a few Nearctic species also have a slender first segment but lack yellow markings on the metasoma). A few other European species are very similar.
Range
Central and northern Europe, apparently introduced to Quebec.
