The Red Mason Bee (Osmia bicornis,
Hymenoptera: Megachilidae) is probably the most abundant solitary bee
throughout Central Europe. We have established a set-up that allows
detailed quantification of many aspects of foraging activity without
any disturbance of the bees. We are interested in the breeding biology
of this species with special focus of the intranidal behaviour,
investment allocation among progeny, and larval performance as a
function of different factors.
