The common Masked bee species Common Yellow Face Bee (Hylaeus communis)^{[1, 2]} turns out to be a frequent visitor to the garden. Besides the beehotel it is also visiting different flowers.

This female was roaming Sheep’s bit scabious (Jasione montana). She has remarkable white hair bands on the abdomen, which could indicate a different species. But for that to be the case the hair band on the first segment (tergite) should be present and much clearer which in this case it isn’t^[2].

Also the stepped clypeus points to Common yellow face bee.
