Mid-June to early July. Local to the south coast of England. Easily identified by the orange-red scales over most of the forewing.

There are two narrow whitish bands on the abdomen on the females, with three on the males. Both have a tail-fan with a central orange-red vertical patch in the centre.

The adults fly by day, usually in sunny conditions and sometimes visit flowers, such as Common Mallow or various composites. They overwinter as larvae, sometimes twice. The caterpillars can be found from August to the following May feeding within the tap roots of larger, typically isolated, plants.
