Acmaeodera delumbis Horn, 1894 .

Adults of this species are frequently collected on legume shrubs (Westcott et al. 1979; MacRae 2006).

One specimen was taken on an apical stem of Ephedra sp. ( Ephedraceae), ARIZONA, Cochise Co., Dragoon Mts., lower Cochise Stronghold FR 84, 1460 m, 20.VII.2010, D. La Rue, RACC. Surely this represents only a resting place and is not indicative of a larval host, both of those known being legumes .
