It is found in China (Tianjin, Shanxi, Zhejiang, Anhui, Fujian, Henan, Sichuan, Guizhou, Shaanxi, Gansu), Korea, Russia and most of Europe.[2] It is also found in North America, where it has been recorded from Colorado, New Mexico, Oklahoma and Utah.[3] The habitat consists of woodlands, chalk downland and cliffs.[4]

The larvae feed on Solidago virgaurea and Aster tripolium. They feed on the seeds within the flowerheads of their host plant.[6] Larvae can be found from August to May. The species overwinters in the pupal stage within a cocoon.
