An extremely rare and local species in Belgium, not often recorded. A highly endangered species in Europe.
Native
Most caterpillars are found in July and August and they live quite concealed when fully-grown.
The adults come rarely to light.
The adults are on the wing from May to August with a focus on the end of June to mid-July, with occasionally a very partial second generation in August/September.
The larvae are oligophagous on rather low growing Asteraceae such as Taraxacum, Leontodon, Prenanthes, Lactuca, Mycelis or Sonchus.
Extensive pastures, meadows and grasslands.
