Nutrition:
Mostly grasses.

Habitat:
Stenobothrus clavatus inhabits dry and warm, often stony slopes between 1200 and about 1800m. These are often extensively grazed.

Life cycle:
The adults are found in summer, mostly between late June and August, rarely probably also later. They may be abundant at suitable places.

Endangerment factors:
Stenobothrus clavatus may be threatened by intensification of grazing, but locally also abandonment and subsequent succession, and also by global warming.

Remarks:
Stenobothrus clavatus is endemic to the southwestern Balkans and occurs in NW-Greece (Epirus, south of Ioannina) on Mount Tomaros and Mount Xerovouni and in southern Albania (e.g. Mount Nemerchka and Griba Mountains).

Hints on determination:
Males are easily distinguishable by their flattened, extended antenna tips. In females the antenna tips are also extended, but much less conspicuous. Typical companion species are Stenobothrus fischeri and - especially in higher altitudes - sometimes also S. rubicundulus. There are hybrids known between S. clavatus and S. rubicundulus on Mount Tomaros.
