features

The fore wing length is twelve to 13 millimeters. The upper side of the forewing is light yellow with large brown-black discal and small submarginal spots. The hind wings are generally brown-black in color with yellow spots, which are arranged like the yellow-cube thick-headed butterfly and with an additional spot on the costa . The bottom is the same as the top. The female has slightly larger spots as well as a dark basal region and a dark outer edge.

The caterpillars are adult grass green with pale back and side back lines. They are up to 25 millimeters long. Before wintering, the caterpillars turn gray-yellow. They overwinter as fully grown caterpillars.

The pupa is pale yellow with brown vertical stripes.

Geographical occurrence and habitat

The black-spotted gold thick-headed butterfly is distributed in northeast Germany, Denmark , Fennoscandia and northeast Europe through Siberia to the Amur , Kamchatka and Japan. In Scandinavia it occurs up to the Arctic Circle , in Western Siberia up to the Taimyr Peninsula . Previously, the occurrence reached south to the Czech Republic; he died there. In Eastern Europe, the southernmost occurrence is in Ukraine . The moth can be found in the lowlands in light forests, moist, sunny forest clearings and in bushy places. In northeastern Germany, the species is also often found along grassy dam paths in moor and swamp forests. It occurs from 0 to about 200 m above sea level.

Way of life

The moths fly in one generation from late May to late June. They like to suckle Speedwell ( Veronica ). The males show territorial behavior and attack other males who invade their territory. The caterpillars live on forest bricks ( Bromus ramosus ), forest twinks ( Brachypodium sylvaticum )? Flutter grass ( Milium effusum ) and meadow crest grass ( Cynosurus cristatus ). At first they live in a bag made of leaves that are spun together, later also freely.
