Nutrition:
Grasses and herbs

Habitat:
Stenobothrus rubicundulus colonizes dry slopes, rocky, nutrient-poor and stony pastures and grasslands. In the Alps it is found in altitudes between 1000 and 2500m above sea level. In Southeastern Europe, from Istria, it descends almost to sea level.

Life cycle:
Adults can be observed from July to early October. They draw attention through their wings buzzing. Males are good fliers.

Endangerment factors:
In places Stenobothrus rubicundulus is threatened by tourist development measures and increased intensity of agricultural use.

Remarks:
Stenobothrus rubicundulus is found in Central Europe only locally, especially in the Central and Southern Alps, so in the Engadine and in the Maritime Alps. Stenobothrus rubicundulus also inhabits the Balkan Peninsula, where I observed it quite common on Mount Phalakro in Northern Greece.
