The genus Megachile is a cosmopolitan group of solitary bees, often called leafcutter bees or leafcu

it also includes the called resin bees and mortar 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 more than 1500 species[1] in over 50 subgenera.[2] The introduced alfalfa leafcutter bee (Megachile rotundata) is managed for crop pollination in various regions around the world.Wikipedia
