Scientific Name: Merophyas divulsana
Common Name: Lucerne leafroller

The lucerne leafroller is a pest of lucerne. Young larvae are pale yellow with dark heads. Older larvae are up to 15 mm long, yellowish-green to green with darker heads. The larvae bind lucerne leaves together at the growing tips of the stems. Several leaves are bent over and joined with silk to form a shelter for the caterpillar. Larvae often drop from plants on silken threads when disturbed. Moths are 8 mm long and are yellow-light brown, often with dark irregular markings on the forewings.
