Leaflets will typically have entire sections of the lamina missing with broad curved margins where the feeding has stopped. Often only the midrib of each leaflet will remain unconsumed. Caterpillars may feed on foliage of any age.
Sri Lanka weevil feeding damage is similar except that this insect leaves round notches about 1/4 inch in diameter along the margins of leaflets on the oldest leaves. Damage from caterpillar feeding is usually much more extensive and can be found on leaves of any age.
