It preferentially inhabits steppes, open shrubby habitats and forest margins from sea level to altitudes of 2000 m. The flight season extends from the end of May to the end of August, with a peak in June. Flowers visited: Achillea millefolium , Astrodaucus orientalis , Euphorbia altissima , Eryngium creticum, Tortilis uranica. The species is moderately recorded in Turkey (11 provinces).

Distribution: All Europe south to Sicily, up to 1500 m, Russia, and from western Morocco, Lebanon and Azerbaijan to Kazakhstan. Turkey: 11 provinces; older data are not usable as the species was previously mixed with H. brevicornis .
