Abstract

Leaf-cutter bees, members of the genus Megachile, family Megachilidae, are useful pollinators of alfalfa and other crops but may cause damage to ornamental plants by cutting circular and oval pieces from the leaves. These pieces are used as linings and caps for cells which are constructed in a variety of locations. Some species nest in the soil, others nest in tunnels of rotting wood, while still others use borings or cavities in wood or in plant stems. One group of Megachile species, the subgenus Chelostomoides, has recently been transferred to the genus Chalicodoma (Michener, 1962). The species of this genus do not cut leaves but use resin to construct their cells.
