Eucosma cana, the hoary bell, is a species of moth of the family Tortricidae.
Distribution and habitat
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.[2][3] These moths mainly inhabit flower meadows, rough grounds and waysides.
Description
Eucosma cana can reach a body length of about 11.5 mm (0.45 in) and a wingspan of 16–23 mm.[4] 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,[4], which has a darker ground color of the forewings, lacking the longitudinal lighter streaks.
Biology
Adults are on wing in a single generation from June to August. [4] The larvae are 10-11 mm long, pale orange or dark ocher, broad and somewhat flat. They feed on the flowerheads of Cirsium, Carduus species and of Centaurea nigra (black knapweed)[2][4] and can be found from August to May.
