These very rare beetles were found sitting on an oak leaves in Haberli (33 km SE Midyat, SE Turkey). Interestingly, the adults tend to gather on selected living trees showing a strong preference for stunted oaks growing on poor stony grounds. This behaviour implies that a semiochemical mediated communication might be used by this species. Calchaenesthes oblongomaculatus diversicollis never visits flowers.
