Watercolor from live specimens found in Maricopa Co., Arizona, USA.  Plant is drawn life-size, actual size of beetle is indicated by the hatch mark.

Several species of brightly colored flat leaf beetles (f. Chrysomelidae, s.f. Hispinae) are commonly found on Sonoran Desert plants. The one shown above is black with red shoulder patches. The larvae, like the adult beetles, are flattened with most being leaf miners ... i.e. they tunnel between the top and bottom layers of a leaf.
