This spectacular moth was once widespread and common throughout the county, but is getting rarer, possibly due to global warming. Although its markings are very varied, which has led to many learned studies, the moth's forewings are usually brown, crossed with white lines, while the hindwings are red or occasionally yellow, with big black spots which have deep-blue centres. It flies mainly at night but is often found during the day, so it can be mistaken for a butterfly.
