Guide to Difficult [moth] Species online

This web page allows you to download PDFs of the now out-of-print "British and Irish moths: an illustrated guide to selected difficult species". It provides keys and detailed illustrations for a wide range of macro-moths that need dissection and/or close examination to identify. Pug moths are not included, but most of the other macro-moth species that can't be identified just from their wing markings are in. Clearly written and well illustrated.
