Larger than the other corporals, it usually perches on the ground or on flat surfaces. Males become pruinose white on the front of the thorax and the abdomen. Females and tenerals have a triangular dark basal patch on the hindwing, broad light stripes on the front of the thorax and a broad dark stripe down the abdomen. Mature females may become thinly pruinose white on the front of the thorax and the base of the abdomen.
