Small size (females usually not or little over 1 inch long, males smaller). Pronotum is much narrower at front than back and has low median ridge cut only once. Hind wings yellow with dark cross band; hind tibiae usually bluish. Outer side of hind femur usually has one prominent dark cross band in front of lighter narrowest part; this may be the only dark band, or if not is darker than other cross bands. Usually one narrow slightly diagonal band across folded tegmina, a little past the middle, that is the only one or the darkest one, and that lines up with the one on the hind femur. Very active and alert; often buzzes faintly when flying.

Most likely to be confused with Arphia, species, but is smaller, and narrowed front of pronotum is distinctive. Buzz produced in flight is fainter and higher pitched.
