The Cinnabar moth (Tyria jacobaeae) is a brightly coloured arctiid moth, found in Europe and western and central Asia. It has been introduced into New Zealand, Australia and North America 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 32-42 mm (1.3-1.7 in).
Cinnabar moths are day-flying insects. Like many other brightly coloured moths, it is poisonous.
