Hello

Terrestrial Heteroptera Recording Scheme, through the Biological Records Centre, have produced 10KM range, recording and seasonal period rules for Terrestrial Heteroptera  (Shieldbugs and allied species). Additionally they have also assigned identification difficulties and highlighted species that require additional verification (species that are rare, new arrivals or establishing).  These are now available to download and use in the NBN Record Cleaner.

Best wishes

Graham
