Pyrausta sanguinalis, the scarce crimson and gold, is a species of moth of the family Crambidae. It is found across western Europe as far east as southern Finland. In the British Isles it was formerly found at multiple coastal locations in NW England and Scotland, however it has now much declined and it is restricted to a few locations in Northern Ireland and a single site on the Isle of Man. The wingspan is 14–18 mm. The moth flies from June to August depending on the location. The larvae feed on Common sage, Rosemary and Thyme.
