The spreadsheet that you can download here contains a list of British and Irish aculeates used by BWARS. This is a list of species and their names, recognised as being present in Great Britain and Ireland, drawn from work being undertaken by Gavin Broad (Natural History Museum), Barry Bolton, George Else, John Burn and Mike Edwards. The list contains our best understanding of accepted names for species, although in a few cases some confusion around names remains.
The spreadsheet is a Microsoft Excel spreadsheet - this will open in MS and Open Office or Libre Office, freely available office applications.
