Larval instar n-1: Head capsule dark brown with coarse, shallow sculpturing on anterior face, spiky texture laterally and dorsally. Epicranial suture extends to slightly less than halfway down front of capsule. Vertex flat with epicranial notch insignificant. White markings extending from adjacent to epicranial suture, upwards to vertex, and along lateral borders halfway down head capsule. White markings on adfrontal areas. Pair of small white oval markings along lower border of frons. Posterior side of head capsule with paired white markings along lateral border, one pair on either side of vertex and one pair on either side of mouthparts. 6 stemmata present, stemma 5 slightly larger than the others and closer to stemma 6 than stemma 4. Body with integument green, dorsally and dorsolaterally patterned with transverse stripes, alternating between several thin bright yellow stripes and pattern of one broad black transverse stripe between a pair of pale yellow stripes. Stripes thinner on T2 and T3 but otherwise similar patterning as abdomen. Prothoracic shield present as a broad black band on white T1. Spiracles black and tracheal system passing through. Pale green subspiracular longitudinal stripe. Body covered in short, transparent setae.Anal shield translucent gray with faint black posterior border and slightly longersetae than the other segments. Legs translucent white. Prolegs yellow.
Larval instar n: Head capsule similar to previous instar but with more extensive cream coloration on anterior and posterior faces. Black anteriorly reduced to along lateral borders, epicranial suture, lateral adfrontal sutures, and two patches in the upper-center of each vertical hemisphere of the head capsule. Body with integument mostly black. Prothoracic shield visible as black band. T2 and T3 dorsally with narrow, bright yellow transverse bands.Abdominal segments dorsally with 2 pale yellow intermediately thick transverse bands, with alternating pattern of either 5 bright yellow thin bands or black space between. Yellow bands do not extend to dorsolateral area. Supraspiracular yellow markings present as in first instar, along with black spiracles and subspiracular band. Legs translucent light green with orange claws. Prolegs orange. Setae and anal shield same as previous instar. Wax glands ventrally on A4–A8.
Pupa: Overall yellow and largely coated in translucent white wax. Head with orange cephalic projection and orange borders of segments. Orange at wing bases. Thorax and abdomen with orange spiracles. Body relatively consistent in width throughout, tapering at cremaster. Cremaster dark orange and covered in dense patches of wax, attached to molt by silken thread.
