Perdita discreta is a Timberlake species, and we have type material
among our 10 specimens, all from NC.
The dates range from Sept. 29 to mid-October, and the only host records
are for Isocoma (2 males, 1 female).
Apropos of Tanner's comments, we also have 17 specimens including the
type series of P. michelbacheri, May-July, mostly from saguaro, and
non-types from boojum tree, one from "Acacia".
