The Cinnabar moth (Tyria jacobaeae) is a brightly colored arctiid moth. It is found in Europe and western and central Asia and has been introduced into New Zealand and Australia to control poisonous ragwort, which its larvae feed on. The moth is named after the red mineral cinnabar because of the red patches on its predominantly black wings. Cinnabar moths have a wingspan of 1.3-1.7 in (32-42 mm).
A survey is currently being undertaken in the UK as a part of National Insect Week. You can vist their site at http://www.nationalinsectweek.co.uk/cinnabarMoth_moth.htm
