Overnight visit by one of the Blairs
Strong (and cold) northerly wind overnight so the numbers and species were down in the moth trap when I checked this morning. However a single Blair's Shoulder-knot was new for the year. This species usually appears in early October and wasn't discovered in the UK until 1951 but has rapidly spread north. The larvae feed on the flowers of garden Cypresses included the often dreaded Leyland Cypress.
