Hello

Auchenorrhyncha Recording Scheme for Britain and Ireland, through the Biological Records Centre, have produced 10KM range, recording and seasonal period rules for auchenorrhyncha  (leafhoppers, planthoppers, froghoppers, treehoppers and cicadas). Additionally they have also assigned identification difficulties and highlighted species that require additional verification (species that are very rare or new arrivals).  These are now available to download and use in the NBN Record Cleaner.

Best wishes

Graham
