northern cactus woodborer bees
Lithurgopsis is a genus of solitary bees in the family Megachilidae, subfamily Lithurginae. These bees are commonly referred to as "northern cactus woodborers" due to their specialized association with cactus wood for nesting. The genus contains at least nine described species distributed across North America, with documented occurrences in the southwestern United States and Mexico. Species within this genus exhibit specialized nesting behaviors, excavating tunnels in cactus stems and provisioning cells with pollen and nectar.
