Description
For a key to the terms used, see Glossary of entomology terms.

This is a fairly small (wingspan 28–35 mm) distinctive species. The white or sometimes bluish-grey forewings are marked with a broad dark olive-fuscous median band. The claviform stigma is black edged; upper stigmata are pale grey with dark centres. The base and outer area of forewing and the head and thorax are pure white. The hindwings are whitish grey with veins and marginal border fuscous. The hindwings are darker in the female.

This species flies at night from June to August[lower-alpha 1] and is attracted to light and various flowers.

The larva is brown or green with darker diamonds along the back. It feeds on the flowers and buds of various yellow-flowered Asteraceae such as hawksbeards, hawkweeds and sow thistles.[1] The species overwinters as a pupa.

Notes
  1. The flight season refers to the British Isles. This may vary in other parts of the range.
