title: Checklist of British and Irish Hymenoptera - aculeates (Apoidea, Chrysidoidea and Vespoidea).
abstract: BACKGROUND
  The checklist of British and Irish aculeate Hymenoptera (Apoidea, Chrysidoidea and Vespoidea) is revised. Species distribution is summarised for all species at the level of country (England, Scotland, Wales, Ireland and Isle of Man).
  
  
  CONCLUSIONS
  The 601 native species represent an increase of 25 on the 1978 checklist, comprising mostly new discoveries. This increase is nearly balanced by the 23 species now presumed to be extinct in Britain and Ireland.
