Biology of Hoplitis tuberculata
In a recently published paper, Müller (2015c) describes nest architecture and flower preferences of the boreoalpine Hoplitis (Alcidamea) tuberculata. The nest architecture of H. tuberculata is unique among Palaearctic osmiine bees. However, it corresponds to that of three North American species closely related to H. tuberculata. For details see the species account on the Palaearctic osmiine bee website.
