This species also likely occurs in British Columbia and Saskatchewan as it is a cleptoparasite of Anthophora peritomae Cockerell which occurs from southern British Columbia to Saskatchewan. Zacosmia maculata desertorum Cockerell is considered a valid subspecies, but has not been recorded from Canada.
Torchio (1971) studied the nesting biology of Anthophora peritomae and recorded Z. maculata as a cleptoparasite. Hicks (1934) recorded it as a nest parasites of another Micranthophora, A. curta Cresson. Torchio and Youssef (1968) described the immature stages (first instar, mature larvae, and pupa) in association with the host Anthophora flexipes. Rozen (1969) also fully described the mature larva, indicating that it was the most hightly modified of all the melectine bees, particularly the pointed labrum. He later provided a detailed description of the first instar, and discussed the mode of parasitism (Rozen 1991).
