features

butterfly

The moths have a wingspan of 21 to 27 millimeters for males and 20 to 37 millimeters for females. The species is characterized by a slight sexual dimorphism . The wings of the females have a cloudy yellow-brown color, are thinly scaly and look like parchment. Except for a few weak spots in the area of ​​the middle field, no clear drawing elements can be seen. The males are usually very dark brown and point to the forewings black spots that form often curved cross lines. The antennae of the males are double combed. The thorax is furry.

Caterpillar

Adult caterpillars are black-gray in color, have a whitish back line and yellowish side lines. Along their entire length they are provided with black warts on which there are black-brown tufts of hair.

Similar species

There is a certain similarity to the dark brown male moths of the gray bear ( Diaphora mendica ), which, however, only show very small, irregular black spots on the forewings. The white colored females can be clearly distinguished.

The brown spotted bear ( Diaphora luctuosa ) differs in its broader front wings.

Geographical distribution and occurrence

The species occurs in the Alps , the Pyrenees and the Apennines and is found at altitudes between 500 and 2400 meters. It prefers to colonize short grass slopes as well as stone and rocky slopes.

Way of life

The diurnal moths form two generations a year in low-lying areas with favorable climates, and can be found in the months of April to June and July to August. At higher altitudes, only one generation appears from May to July. The males fly in the sunshine, the females sit in the vegetation and are flightless. The caterpillars appear from late summer and feed on various low plants such as dandelion ( Taraxacum ) and plantain species . They overwinter and pupate in spring.

Danger

The Alpine Fleckleibbär occurs in Germany only in Bavaria and is listed in Germany on the Red List in Category 1 (“threatened with extinction”).
