Length: male, 1 in.; female, 1 1/4 in.; similar to herbaceus but richer brown; hind tibiae deeper blue; male furculae narrower, apical half narrow and apex expanded into round lobes; male cerci very broad at base, narrowing decidedly to slightly expanded apex (Fig. 9 5), Eggs, sixteen to thirty-eight per pod; adults, May 19 (Yuma) to November 18 (Tucson). This is not an important economic species but does considerable damage to small plantings of alfalfa, cotton, soybeans, and other cultivated crops. Common on many weeds and such plants as Hymenoclea monogyra, Baccharis glutinosa, Baccharis sarothroides, Flourensia cernua, and Suaeda. Most common in the Lower Sonoran Zone but also found in the Upper Sonoran Zone from southern and western Arizona (Boulder Dam) to Granite Dells, Yavapai County, and Pinal Mountains.
