The caterpillar when full grown is whitish-green, dotted with white. From the larger of these dots on the back arise greyish bristles; the three lines on the back are whitish, edged with dark green; the line on the sides is white, fringed with greyish hairs; anal points green, hairy, extreme tips white. Head larger than the first ring, green dotted with white and hairy,jaws marked with brownish.The chrysalis is green, with yellow-tinted white markings on the edge of the wing covers and ridges; the spots on the body are yellowish, or sometimes white. Occasionally the chrysalids are blackish, with white or yellow points on the body".
