The Dark Bordered Beauty moth, Epione vespertaria (Formerly known as Epione paralellaria) is similar in appearance to the more common Bordered Beauty moth (Epione repandaria), but the purplish border on the forewing is of even width; in the Bordered Beauty, the outer border tapers sharply towards the tip of the wing. The sexes are different in appearance; males are darker and more orange in colour than the pale yellow female (4). The caterpillar is greyish brown with a whitish, violet-tinged underside (4).
