In life the pale parts are green fading to yellow. In the female the head is light yellow with black on the anterior of the postocellar area. Also the female has the thorax and abdomen light yellow with black on the mesonotum, scutellum, middle of the metanotum, and sometimes the mesosternum. The scutellum sometimes has two bright spots and broad streaks on the dorsum of the abdomen. In the male the head is black, with yellow more or less on the lower portions and the orbits. Also the male has the thorax and abdomen black with yellow on the corners of the pronotum, the tegulae and the underside of the abdomen. The legs are yellow with the apices and tarsi of the hind legs marked with black. The antennae are pale on the underside.
