Hoary Bell

Eucosma cana can reach a body length of about 11.5 mm (0.45 in) and a wingspan of 16–23 mm. The head of these moths is reddish brown, while the thorax is light brownish on the sides, dark brownish in the middle. The ground colour of the forewings is light brown or greyish, with light longitudinal discal streaks. The edges are feathered. The hindwings are dark gray toward the margins. This species in rather similar to Eucosma hohenwartiana, which has a darker ground colour of the forewings, lacking the longitudinal lighter streaks. Meyrick describes it -The forewings are elongate, fold reaching to near middle; ochreous, somewhat blackish -sprinkled, with several suffused ochreous whitish longitudinal streaks confluent in middle towards base, ceasing before very narrow central fascia of ground-colour; an oblique wedge-shaped ferruginous suffusion from dorsum near base; posterior half of costa with very oblique whitish strigulae, abruptly ceasing at 1/3; ocellus metallic-edged, containing one or two incomplete black dashes; termen sinuate. Hindwings in male pale grey, darker terminally, in female darker. The larva is dull pink; head and plate of 2 brown.

This quite common and widespread species can be found in most of Europe, in China (Zhejiang, Fujian, Henan, Guangdong, Yunnan, Shaanxi, Gansu, Xinjiang), in Japan, in Central Asia, in Russia, and in Kazakhstan. These moths mainly inhabit flower meadows, rough grounds and waysides.
