If you know of records not shown on these maps, then it is probably because they have not been submitted to the recording scheme. Please provide us with your records if you have not already done so - the maps can only be as up-to-date and comprehensive as the data provided! Either provide your records to the County/Area Organiser or Contact us giving the species name, date of your record, location and map grid reference or postcode. Unless you are an experienced arachnologist please also provide an image or voucher to support your record wherever possible.
