Adult male has grayish-brown wings (A); the female has remnants of wings and so cannot fly. This, in combination with the female's large body, makes the legs appear to be long, and gives her the superficial appearance of a spider (B). Early larva is olive-green with a black head; later forms are a brighter green, with white stripes along the back and sides (C).
