Hairy-toothed Leafcutter Bee
A medium-sized leafcutter bee (9–11 mm) that nests in pre-existing cavities under stones, in rock crevices, and in dry stone walls. It cuts circular pieces from leaves to construct its brood cells. It prefers Fabaceae flowers but is broadly polylectic. In Switzerland it is mainly found in the warm Valais region, flying from June to August in dry meadows, vineyards, and gravel pits. Swiss Red List: Vulnerable (VU).
