Rozen (1993) describes the nesting biology of Sphecodosoma dicksoni, including photos and illustrations. Nests have been collected from a site near Animas, NM, and Blythe, CA, USA. Nests were excavated in a sparsely vegetated area at the base of a sand dune interspersed with Nama hispidum plants, which the bees use for pollen. Some nests were aggregated (10 in an area 1.5 x 0.5 m), while others were scattered individually. In both the CA and NM sites, nests were dug into sloping ground. In CA all nests were occupied by one female, but in NM some were occupied by two or three females. It is unknown if there is divison of labor between the females. Nest architecture consisted of a main burrow with lateral burrows branching off 10 - 25 mm horizontally. In CA, these burrows ended in a series of 2-4 cells arranged end-to-end, however in the NM collections, only single cells were at the end of each lateral burrow. After provisioning of the cell, the lateral burrows were closed. Nests were provisioned with pollen from the plant Nama hispidum.
