Biology

Neff and Simpson (1997) provide a detailed account of the foraging behaviour and nesting biology of this species, indicating that pollen collection was restricted to the coneflower genera Rudbeckia and Ratibida. They also indicate that Nomada (Phelonomada) belfragei was a nest parasite of this species (Neff and Simpson 1997).
