Like the other tiger moths this is a large colourful moth with bold markings. Its distinctive features are its black forewings with cream spots, yellow hindwings and a furry black thorax.
When disturbed it will display its hindwings and its orange/red abdomen to warn off predators.
It spends most of the year as a larva, from July to late April or early May, before pupating in a cocoon amongst low vegetation. The adult moth then emerges after about 20 days.
