Bombus (Psithyrus) rupestris

(Fabricius, 1793)

Author(s) : Rasmont P
Bombus rupestris lives from the middle of the Iberian peninsula, the S. Italy and the Balkan to the South to the middle of Scandinavia to the North. It can be found from Ireland to the West to East Sibiria to the East. It inquilines mainly B. lapidarius but also B. sichelii and likely other species from the subgenus Melanobombus.
