The Highland Branch of Butterfly Conservation has produced a Butterfly Atlas covering the Highlands, Moray, Western Isles & Northern Isles.  You can download this from our website, https://butterfly-conservation.org/in-your-area/highlands-and-islands-branch/butterfly-species-atlas, free of charge, however, if you are able to give a small donation it would be most appreciated.  You can also donate here if you'd like to help us conserve butterflies and moths in the branch area which covers the Highlands, Moray, the Northern Isles and the Western Isles.
