The Bärenklauwickler ( Pammene Aurana ) is a butterfly from the family of the winder (Tortricidae), which occurs from Western Europe to East Asia.

features

The hogweed curler has a wingspan of 9 to 13 mm. The forewing is dark to black-brown with two yellow-orange spots, a medium-sized angular or broad sickle-shaped in front of the outer edge of the wing and a large semicircular in the middle on the rear edge of the wing. The fringes are dark brown, blackish directly on the wing. The hind wings are dark, the light gray-brown fringes are darker on the wing. The head is brown with a purple tinge. The thorax , tegula and abdomen are brown to dark brown. The antennae are dark brown.

In the aurantiana form , the two spots flow together and only the base of the wing, the costa and the outer edge are brown.

The caterpillar is pale ocher with a dark brown head. The prothorax is brown with a distinct, lighter furrow in the center.

Similar species

  • Phaulernis fulviguttella ( Zeller , 1839) is colored the same and the caterpillar eats the same plants. The head of the butterfly, however, is orange and the spot at the apex is further away from the tip and outlined more blurred.

Geographical distribution and habitat

The hogweed moth occurs locally throughout Central Europe, as well as in the rest of Europe, including the British Isles . To the east, it spreads over southern Siberia, the Alatau to the Primorye region in the Far East. Information about occurrences in North Africa and Asia Minor is missing.

The moths are widespread, though not common, even if the host plant is common. They occur in gardens, forest clearings and on the edges of forests and roads.

Way of life

The eggs are laid in June / July on developing seeds of hogweed ( meadow hogweed ( Heracleum sphondylium ), but also hercules shrub ( Heracleum mantegazziannum )). From August the caterpillars can be found that spin two or more seeds together and live in the seed pods. When they are fully grown in late autumn, they leave the capsules and spin into the soil to pupate and overwinter. The moths hatch in June and July of the following year.

The moths fly abruptly and unpredictably. In the late afternoon they suckle on hogweed flowers. The moths are occasionally attracted by light .
