description Megachile fidelis Overview

Megachile fidelis, commonly known as the faithful leafcutting bee, is a solitary bee species native to meadows and gardens across western North America. First formally described by entomologist Ezra Townsend Cresson in 1878, the insect is distinguishable by its dark coloring and the females' practice of cutting neat, circular pieces from leaves and petals. These leaf fragments are used to construct and line individual nest cells, typically in pre-existing cavities or underground burrows. As a pollinator, it plays a vital ecological role in the reproduction of various wildflowers and regional agricultural crops.
