The white forest porter ( Aulocera circe ) is a butterfly (day butterfly ) from the noble butterfly family (Nymphalidae). The specific epithet is derived from Circe , a sorceress from Greek mythology .

features

The moths reach a wingspan of 55 to 65 millimeters. They have very dark brown colored wing tops on which a conspicuous, wide white transverse band, which divides into individual spots on the wing outer edge. The broad, whitish band can also be seen on the dark gray-brown underside of the hind wings. But it is a bit dull in color. There is also a weakly indicated second band near the base of the wing, which clearly distinguishes this species from the great forest porter ( Hipparchia fagi ). But it only extends to the middle of the wing. On the underside of the forewings, near the tip, there is a large gradual white spot with a black point in the middle.

Way of life

The moths fly annually in one generation from early June to mid-September. In contrast to the Great Forest Porter, you can often see them on blossoms.

development

The females throw their eggs on the ground in flight. The caterpillars then look for a suitable forage plant. They overwinter when they are adolescents and pupate the next year in an underground chamber.

Food of the caterpillars

The caterpillars feed on the leaves of upright brusque ( Bromus erectus ) and real sheep fescue ( Festuca ovina ). They can also be found on other sweet grasses .

Occurrence

The animals are found in southern and central Europe , Turkey , Iran and the Himalayas up to an altitude of 1,650 meters. They are particularly common in the Mediterranean area , but are very rare in the warm areas of southern Germany . They are particularly found on dry grass near forests .

Hazard and protection

The white forest porter has become rare or has become extinct in many areas. Measures for the conservation of the species are difficult because the species neither populates completely free grasslands or heather nor overbush areas.
