The anvil-cube-thick-headed butterfly ( Pyrgus onopordi ), also known as the south-western cube-shaped thickhead , is a butterfly from the thick-headed butterfly family .

features

The fore wing length is 11 to 14 millimeters. The moth is dark brown with a slightly yellowish tinge. The fore and hind wings have distinct yellowish spots. The spot in cell seven is particularly pronounced . The underside of the hind wings is light yellow-brown and slightly dark marbled with yellow veins. Noticeable is a large anvil-shaped discoidal spot in cells four and five and another spot in cell 1c. The female is usually somewhat larger, has a darker top and is usually scaly yellow.

The yellowish egg is round and flattened at both ends. It has up to twenty strong longitudinal ribs on the surface.

The caterpillar is light to dark brown with light side ridge lines. She has a black head.

The pupae are bluish frosted with a very high-contrast drawing, whereby the drawing on the back of the thorax is often broken up into spots and lines.

Geographical occurrence and habitat

The anvil-spotted cube-head butterfly is native to the Iberian Peninsula , in southeast France and in Italy , in the north up to the 46th parallel, including the Valais Rhone Valley and the southern Alps. In North Africa he can be found in Morocco and Algeria . A single occurrence in the Swabian Alb (from 1928) has since been extinguished. A questionable occurrence in Slovenia that has been reported in the literature has now also disappeared. The species can be found on hot rock slopes rich in flowers, grasslands and abandoned dry cultivated land up to over 1400 meters (in the north of the distribution area) or over 2500 meters in the Sierra Nevada (Spain).

Way of life

One to three generations are trained each year. The moths fly from May to October. The caterpillar overwinters in the L4 stage, and if the eggs are laid later, also in younger stages (from L1). The caterpillars feed on Potentilla hirta , Potentilla pusilla and probably also on creeping cinquefoil ( Potentilla reptans ), Apennine sunflower ( Helianthemum apenninum ) and common mallow ( Malva neglecta ).
