Following the  1992 Earth Summit in Rio de Janeiro the UK Biodiversity Action Plan (UK BAP) was devised to focus action on the conservation of "priority" species and habitats, with the list of species being amended after a review in 2006/2007

The UK BAP list for moths is divided into two sections: a priority list of  scarce/threatened species and and a subsidiary list, designated "Research only", of species that are wide spread but which declined rapidly over the period 1968 to 2007.

The following species occurring in Caithness feature in the UK BAP (in alphabetical order)
The quoted percentage declines are taken from:
 Fox R, Parsons M S, Chapman J W, Woiwod I P, Warren M S, & Brooks D R (2013) The State of Britain's Larger Moths 2013
