The caterpillars of this species lack the spike on the tail that many caterpillars in SPHINGIDAE have, but the last abdominal segment is huge, and the body tapers to a tiny forked head. The caterpillars are green and covered in small warts. There is a diagonal yellow stripe on each side of each abdominal segment.
