Camponotus acutirostris

This species is rarely collected. It nests under stones, in areas of rocky gravel. Brood was found in nests in March. (Mackay and Mackay 2002)

Identification
The majors of this species are easily recognized as the clypeus is extended into a sharpened angle or beak-like protection (Fig. 348). The head is wide as seen from front. Major workers and females always have 10 or more erect hairs on the cheeks and malar area. The metanotal suture is well depressed, with the mesosoma in profile. The clypeus of the minor worker is similar, but not as elongate. (Mackay and Mackay 2002)
