[adapted from description by Charles Covell (1)]

Larva: body bright green, elongate and somewhat flattened with prominent yellowish subdorsal stripe; anal prolegs splayed; prolegs on third and fourth abdominal segments slightly reduced in size; head large, green, unmarked; labrum creamy; hairs short and inconspicuous
