Adults are medium to large in size, broadly spindle shaped, red-brown to dark brown or dull red, and have black cornicles.

Food

". . . Most Uroleucon species are monophagous on particular host plants from the Asteraceae, and U. ambrosiae appears to specialize on the giant ragweed, Ambrosia trifida, in eastern North America. In the American Southwest, however, U. ambrosiae uses a variety of asteraceous taxa as hosts. " Ecological society Journal
