Species Notes

Though Grigarick and Stange (1968: 54) indicate the holotype was collected at Wilson's Peak, Strawberry Valley, California, Cockerell (1904: 23) indicates that these represent two separate locations in California, thus there are two syntypes.

 

Michener (1935) and Timberlake (1943) commented on the nesting biology of D. singulare (subspecies perluteum), indicating that it builds single-celled nests on the side or face of rocks out of resins and pebbles. This summer active bee tends to prefer plants in the family Compositae (Grigarick and Stange 1968).
