The genus Diadasia only occurs in the New World and has been traditionally
collected in western and south-western parts of the United States, though it also occurs
in western Canada (Hurd et al. 1980, Sheffield et al. 2017). This species has the
largest distribution of any species of Diadasia, ranging from Washington and California
on the west coast, east through Texas and Missouri (Hurd et al. 1980). Descriptions
and illustrations of the ground nests have been published (Bohart 1952, Linsley and
MacSwain 1957). The documented range of D. enavata was recently extended into
Arkansas (Stephenson et al. 2018) and now into Mississippi.
Over 100 specimens of D. enavata have been collected from Bolivar, Sunflower,
Sharkey and Washington Counties in the Delta region of Mississippi (Fig. 7). The
majority of the specimens were picked up in bee bowls in or around sunflower fields,
though specimens were also picked up in corn, soybeans and sorghum fields.
