Calophasia opalina ( syn. Calophasia casta ) is a butterfly ( moth ) from the family of the owl butterflies (Noctuidae).

features

butterfly

The wingspan of the moth is 26 to 31 millimeters. The forewings are bright white in color, but darkened brown-gray to blue-gray in the middle field and the subterminal region and connected by a bridge. Blemishes and cross lines are missing or indistinct. A white v-sign often stands out in the middle of the outer edge . The hind wings are colored white without drawing, slightly darkened on the outer edge and provided with silky white fringes. The head and thorax are also covered in silky white hair. Due to the very characteristic drawing elements, the species is unmistakable. The proboscis is well developed.

Caterpillar, pupa

Adult caterpillars have a gray-white basic color, a yellow back line and are provided with black secondary back lines interrupted at the segment incisions and on the sides with yellow spots and many small, black dots.

The doll is yellow-brown in color.

distribution and habitat

The occurrence of Calophasia opalina extends widely through southern Europe and eastward with some gaps as far as Central Asia. It prefers to settle on warm slopes, dry lawns and sand dunes.

Way of life

Calophasia opalina forms two generations per year, whose moths can be found from April to June and from July to September. They become active at dusk, visit different flowers to take in nectar and sometimes appear in numbers in artificial light sources in the second half of the night . The caterpillars feed on the leaves and flowers of different snapdragon - ( Antirrhinum ), Larkspur - ( Delphinium ) or Leinkrautarten ( Linaria ). The pupae following the first generation spend a pupal rest of only 14 to 16 days, those following the second generation overwinter.
