The Robust Sunflower Leafcutter Bee (Megachile fortis) was historically found across much of central North America. However, it has declined dramatically in some portions of its range as its grassland habitats have been lost to agricultural intensification, grazing, and herbicide use. The species has not been recorded in New Mexico since the 1990s, though survey effort has likely been minimal. This species nests in cavities, and adults forage primarily on sunflowers (Helianthus spp.), a genus of plants in the aster family (Asteraceae).
