features

butterfly

The moths reach a wingspan of about 24 to 30 millimeters. A changing black and white or brown and white color pattern on the forewings is noticeable. A typical wing drawing shows the following color sequence: a small region at the wing root is dark gray, the adjoining basal region is lighter gray, the broad and outwardly strongly jagged disk region is black-brown to black, the post- disk region is gray-white and the submarginal region is tinted brown-gray. The transitions between the individual regions are sometimes sharply defined, but occasionally also indistinct. There is a kidney-shaped spot in the disk region. The hind wings have a silky white shimmer and are bordered by a dark gray band on the outside. In addition, a very small, black central spot can be seen. The antennae of the males are combed, those of the females are thread-like.

Egg, caterpillar, pupa

The egg has an oval shape, is yellowish at first and later turns pinkish-red.

Adult caterpillars have a dark brown color, a black topline and an indistinct black and yellow side stripe.

The doll is light brown in color.

Geographical distribution and occurrence

The eastern occurrence extends over the Altai and Sayan Mountains to Kamchatka . There are also deposits in Canada . The species is found in the Alps at altitudes between 900 and 2500 meters. It prefers to live in damp places in mountainous areas.

Subspecies

  • Colostygia turbata turbata , (Alps, Southeast Europe)
  • Colostygia turbata fuscolimbata , (Northern Europe)
  • Colostygia turbata pyrenaearia , (Pyrenees)
  • Colostygia turbata altaicata , (Altai, Siberia , Kamchatka)
  • Colostygia turbata circumvallaria , (Canada)

Way of life

The moths fly in the months May to August. They are predominantly diurnal and rarely fly to artificial light sources . The caterpillars feed on the leaves of bedstraw species ( Galium ). They hibernate. Pupation takes place in a cocoon in the earth.
