Megachile campanulae
Bellflower Resin Bee
Megachile campanulae, commonly known as the bellflower resin bee, is a solitary mason bee native to eastern North America. Described in 1903, this species belongs to the subgenus Chelostomoides, distinguishing it from leafcutting relatives by its use of plant resins, mud, and pebbles rather than cut leaves for nest construction. In 2013, researchers documented this species as one of the first insects known to incorporate synthetic materials, including polyurethane-based sealants, into nest construction. The species is an important pollinator of native plants and is nonaggressive toward humans.
