Leafcutter bees resemble small bumble bees. They cut circular pieces of leaves from plants such as Eastern redbud, rose, and azalea. The bees use the pieces of leaves as a lining for their nests. Leafcutter bees are solitary and nest in rotten wood, hollow stems of plants, holes in solid wood, or in other protected natural cavities. They do little damage and control is not necessary.
