Megachile nigriventris
Black-brushed Leafcutter Bee
A medium-sized leafcutter bee (10–12 mm) with a black scopa (pollen brush) on the underside of the abdomen, which distinguishes it from many other Megachile species. It nests in dead wood, excavating tunnels in rotting timber or using existing beetle burrows. It lines its brood cells with cut leaf pieces. It is polylectic and flies from June to August in forests, forest edges, and orchards. Swiss Red List: Least Concern (LC).
