Megachile

Comparison between modern and fossil pupae from the La Brea Tar Pits

The genus Megachile is a cosmopolitan group of solitary bees, often called leafcutter bees or leafcutting bees. While other genera within the family Megachilidae may chew leaves or petals into fragments to build their nests, certain species within Megachile neatly cut pieces of leaves or petals, hence their common name. This is one of the largest genera of bees, with almost 1500 species in over 50 subgenera. North America has many native Megachile species. The introduced alfalfa leafcutter bee (Megachile rotundata) is managed for crop pollination.
