Nesting biology of Centris (Paracentris) burgdorfi (Apidae: Centridini)

We describe the nesting biology of Centris (Paracentris) burgdorfi, a solitary bee that nests in sandstone in northeastern Brazil. The nest consists of a shallow tunnel with access to the brood cells. Females of C. burgdorfi made 1–7 brood cells per nest with each cell requiring 2.58 ± 0.40 (X¯ ± SD) days to construct. The average cell-building construction time was longer when compared to other Centris species. Females were larger than males,...
