Taxonomic group: bees and wasps (Aculeata) - County data
Less than 20 years ago this wasp was considered to be one of the great aculeate rarities in Britain, with colonies only in sandy habitats on the Isle of Wight and Suffolk. It has since undergone an expansion in range, with the wasp now locally common in a steadily increasing number of sites (Edwards, 1997) as far north as Yorkshire (Archer, 2002). In view of the expansion in range and the probability that this is climate driven, its status should be revised, although it is still very local in much of the Essex countryside. References
