Abstract

Observations on the nests of two chalicodomes and their occupants in Sardinia (Italy). - We here provide field observations made in spring 2008 in Sardinia on the nesting biology of two mason bees, Megachile (Chalicodoma) parietina (Geoffroy in Fourcroy 1785) and M. (C.) sicula (Rossi 1792) whose females occasionally construct egg-shaped nests perched on tree twigs. Active nests of M. (C.) parietina were also exploited by females of Osmia signata Erichson 1835 and those of M. (C.) sicula were found to be parasitised by Leucospis gigas Fabricius 1793.
