Stroupeč Natural Monument is a steppe locality situated on the left side of the canyon of Ohře river approximately 5 km eastern-north from Žatec. The locality is characterised by grasslands composed mainly of Festuca valesiaca, Carex supina and others. Herbaceous cover is on steep parts occasionally disturbed by erosion and landslide which benefits xerothermic rare species such as Artemisia pontica or Astragalus exscapus. Lower parts of the locality are partially covered by trees and shrubs such as Quercus robur and Ulmus minor. Stroupeč Natural Monument is xerothermic locality harbouring the great number of steppe species of insect, including rare Cylindromorphus bohemicus (Coleoptera: Buprestidae), Mycterus tibialis (Coleoptera: Mycetridae), Pseudophilotes vicrama (Lepidoptera: Lycaenidae) or Hipparchia semele (Lepidoptera: Nymphalidae).

At this locality, we recently conducted a fieldwork study focusing on habitat requirements of Cylindromorphus bohemicus. We systematically observed bunches of Festuca valesiaca in order to find C. bohemicus adults sitting on the grass. We recorded many environmental parameters such as herbaceous cover around the bunch, steepness, or size of the bunch. These data will be analysed for habitat requirements of C. bohemicus potentially offering useful insights for sustainable management at areas inhabited by this species.
