Camponotus vagus

Identification
Collingwood (1979) - In this group of species the anterior border of the clypeus is entire, straight or feebly convex and does not extend beyond the mandibular insertions. The alitrunk in the worker caste is high and steep sided; in profile the dorsum is convex without a break, the dorsal face of the propodeum abruptly curving into the long almost vertical basal face. From above the pronotum is much wider than the rest of the alitrunk which narrows to half its width posteriorly. Mandibles are large: with five strong teeth which are often blunted and worn in the larger workers. The male has the mandibles slender with an apical tooth only.

Uniformly black with profuse body hairs. The sculpture is finely transverse and closely punctured, obscured by long thick pubescence. Length: 6-12 mm.

Distribution
A South European species abundant in the Mediterranean area, but recorded from Portugal to South Russia and the mountains of North Africa to Poland (Collingwood 1979).

This taxon was described from Austria.

Biology
C. vagus nests in dry rotten wood among roots under stones in dry sun exposed banks. It is an active aggressive species biting freely on disturbance. As with other species of this group it is both carnivorous and aphidicolous. According to Pisarski (1961) alatae have been recorded in July in Poland where it occurs very locally in the Centre and South.
