Trichoferus griseus belongs with sister taxon Trichoferus holosericeus (Rossi, 1790) among the most widespread and common Western Palearctic representatives of the Trichoferus genus, occurring throughout the Mediterranean, the Middle East, and Asia Minor. The larva develops in dead weaker trees, trunks and branches with a diameter of 2-18 cm, both under the bark and in the wood. Rarely, larvae also develop in barkless wood. Overwinters in the larval stage, life-cycle is biennial to perennial, depending on wood moisture. Adults hatch in southern Europe in late June or July. T. griseus is a nocturnal species living very secretly, but often is attracted by light. Beetles hide under the bark, in wood crevices, etc. during the day. This species is often confused with other species of the Trichoferus genus.
