Megachile latimanus, commonly known as the broad-handed leafcutter bee, is a species of solitary bee found in North America. It is characterized by its large size and broad forelegs, which are adapted for cutting and carrying leaf fragments. These bees construct nests by lining pre-existing cavities with leaf pieces, where they lay their eggs and provide provisions of pollen and nectar for their offspring. Megachile latimanus plays an important role in pollination, particularly for plants in the rose family.
