Megachile angelarum is an essential native resin bee adapted to the arid environments of the American Southwest. Unlike social honey bees, these solitary bees do not live in colonies or build large hives, making them completely non-aggressive. Their presence is a vital indicator of healthy, diverse native plant communities throughout the Mojave Desert.
