Eodorcadion
Eodorcadion
Among the most recognizable flightless longhorn beetles of the Central Asian steppes, *Eodorcadion* Breuning, 1947 comprises robust, broad-bodied species whose dense, cryptic pubescence renders them remarkably difficult to detect against sun-baked grassland soils. Adults emerge from April to June, spending their brief active season on or near the host grass stems from which their larvae have spent one to two years excavating the root system. With 62 Palaearctic species, many restricted to isolated steppe fragments, the genus stands as a striking example of allopatric diversification driven by grassland fragmentation across Kazakhstan, southern Siberia, Mongolia, and north-western China.
