Foraging and mating behavior of Perdita texana, an oligolege on Opuntia flowers, are described. Head widths of males are highly variable and skewed toward larger size. P. texana appears not to be a pollinator of Opuntia, since it rarely contacts the stigma. On a sinigle flight, a female gathers her entire pollen load in one flower.
