About Eucosma aspidiscana (Hübner, 1814-1817)
Eucosma aspidiscana, commonly known as the golden-rod bell, is a moth species belonging to the family Tortricidae. It can be found in China (specifically in Anhui, Henan, Shaanxi, and Gansu), Mongolia, Korea, Japan, Russia, North Africa, and most of Europe. Its natural habitat includes woodlands, downland, waste grounds, and cliffs. The wingspan of this moth ranges from 13 to 20 mm. Its forewings are ochreous brown, with some mixing of paler and darker scales that tend to form longitudinal streaks in the disc. The dorsum is partly darker fuscous, and the posterior costa has alternating whitish and dark fuscous streaks. The area between the basal patch and the central fascia has a faint greyish tinge. Three streaks from the posterior costa and the margins of the ocellus are leaden-metallic, and the ocellus contains three black dashes. The hindwings are fuscous, and become darker toward the terminal end. Adult moths are active in flight from the end of April to June. The larvae feed on species of the genera Solidago, Crinitaria, and Aster. Larvae can be found from August to April.
