Pyrausta sanguinalis

Description

Pyrausta sanguinalis, the scarce crimson and gold, is a species of moth of the family Crambidae. The species was first described by Carl Linnaeus in his 1767 12th edition of Systema Naturae. 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 north-west 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.
