Nutrition:
Grasses and herbs, and on occasion even carrion like crushed insects etc.

Habitat:
Arcyptera fusca inhabits nutrient-poor grasslands, extensive pastures, clearings in dry mountain forests, rocky slopes and similar places. Arcyptera fusca occurs only in dry, warm, well sun-drenched habitats with open ground.

Life cycle:
The adults occur from late June or early July to October. The eggs overwinter in the soil, often several times.

Endangerment: threatened with extinction

Endangerment factors:
In Germany only a few remainders of the former distribution are still occurring in a very limited area in the Swabian Alb. In Munich (calcareous heathlands in the north), Arcyptera fusca already disappeared a long time ago, whereas extinction took place only recently near Augsburg (negative habitat changes). In the Southern Alps and the central west Alps, for example, in the French Haute Provence, Arcyptera fusca is still one of the most common species (up to around 2500m asl).

Remarks:
The Eurasian species occurs locally in south and south Central Europe (southern and central Alps, the Pyrenees, Southern France, the Balkans) and parts of Asia (to the east to Mongolia).
