Anthidium maculosum
Spotted Woolcarder
Anthidium maculosum is a solitary carder bee in the family Megachilidae, notable for its unusual sexual dimorphism where males are significantly larger than females—a reversal of the typical bee pattern. Males establish and defend territories around flowering patches of Monarda mint, while females practice polyandry, mating multiple times to gain access to guarded resources. The species ranges from the Pacific Northwest through Mexico to Honduras.
