butterfly

The wingspan of the moth is 20 to 23 millimeters. The basic color of the forewings varies from red-brown to gray-brown. On the front wings are several whitish, undulating cross lines that stand out at times weak. The lines delimiting the midfield are more prominent. A very thin black, interrupted stripe usually runs along the outermost edge of the hem. Several bright wavy lines can be seen on the hind wings. Discal spots are missing.

The oval shaped egg is bright yellow in color. The micropyl rosette has six leaves.

Adult caterpillars are pink to reddish brown in color and show a light side stripe as well as dark angular markings on the back from the sixth to the ninth segment.

The doll is shiny reddish brown in color and has two short thorns on the cremaster .

Geographical distribution and occurrence

The distribution area of ​​the hill master spanner stretches from the Iberian Peninsula through Western and Central Europe to the Central Asian mountains. The warmth-loving species prefers to live on chalky soils and can be found on sunny slopes, hot wasteland and sandy lawns.

Way of life

The moths of a first generation fly from late April to early June. A second generation appears patchy in the months of July and August. Sometimes the moths suckle on the flowers of the barberry ( Berberis vulgaris ) during the day . At night they visit artificial light sources . The caterpillars feed on Hill-Meier ( Asperula cynanchica ), daisies ( Bellis perennis ) and bedstraw species ( Galium ). The species overwinters as a pupa.
