features

butterfly

The wingspan of the moth is 16 to 23 millimeters. The basic color of the forewings varies from ash gray to blackish. The light wavy line near the hem is broken up into white spots, two to three of which are very distinct and the spot at the inner corner is particularly prominent. The black center point is sometimes only faintly indicated. The hind wings are slightly lighter than the fore wings. Increasingly, melanistic specimens appear that are identified as f. angelicata . These moths are black without drawing on the fore and hind wings. Only the veins and the center point stand out.

egg

The egg has an oval shape and shows hexagonal depressions in the shell sculpture.

Caterpillar

Adult caterpillars are either greenish or brownish in color and show very distinct dark, heart-shaped, light-edged dorsal spots, the tips of which are directed forward.

Doll

The brownish doll has dark green wing sheaths and is provided with two strong and six thin hook bristles on the cremaster .

Geographical distribution and occurrence

The three-point moth is widespread in Europe. Its occurrence also extends through Asia to Japan and the Kuril Islands . In the Pyrenees and the Alps , it rises to an altitude of 1,800 meters. Another distribution area is in North America, from Newfoundland to British Columbia and the San Bernardino Mountains . The species prefers swamp and alluvial forests, forest edges and wet meadows.

Way of life

The moths are crepuscular and nocturnal and fly in two generations from April to June and from July to September. Sometimes they suckle on the flowers of the meadow chervil ( Anthriscus sylvestris ). They also appear in artificial light sources . The caterpillars feed polyphagously on the flowers and seeds of various plants, including: forest angelica ( Angelica sylvestris ), little beaverfish ( Pimpinella saxifraga ), black elder ( Sambucus nigra ) and wild hogweed ( Heracleum sphondylium ). Although the caterpillars are sometimes very numerous, they often result in only a limited number of butterflies, as they are often infested by parasites. The second generation pupae overwinter.

Danger

In Germany, the three-point moth occurs in all federal states and is not endangered. The species is therefore not mentioned in the Red List of Threatened Species .
