Nesting biology of two Osmia (Melanosmia) species uncovered

In two recent publications, the nesting biology of Osmia (Melanosmia) laticeps (Theunert, Beiträge zur Naturkunde Niedersachsens, 72, 53-71, 2019) and Osmia (Melanosmia) uncinata (Müller et al., Alpine Entomology, 4, 157-171, 2020) are described. The first species nests in insect burrows in dead wood, whereas the second constructs its brood cells within self-excavated short burrows in the bark of living trees and dead stumps of Pinus sylvestris or – more rarely – Larix decidua (see species accounts for details).
