Larvae tunnel between the layers of the leaf, attacking and killing leaves closest to the water. The larvae are legless, transparent or cream-colored. Larvae become yellow to green light as they feed. The larvae or pupae can be found by separating the layers of the leaf. Mature larvae are about ¼ inch long; they feed for 5 to 12 days before pupating.
