Calchaenesthes oblongomaculatus (Guérin, 1844) 
ssp. oblongomaculatus (Guérin, 1844) 

Body length: 10 - 15 mm
Life cycle: 2 - 3 years
Adults in: May - June
Host plant: oak (Quercus)
Distribution: Greece,Turkey, Near East

The living beetle and the mounted beetle (left) was beaten from a blossoming hawthorn (Crataegus) in locality situated along the main road from Sparta to Tripoli on a mountain plateau (20 km S Tripoli, 900 m, Peloponnese peninsula, Greece).

The mounted beetle (right) was found sitting on an oak leaf in the environs of Erdemli W Mersin (SW Turkey). Interestingly, the beetles 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.
