Sri Lanka weevil damage appears as small (typically less than 1/4 inch) notches in the leaflet margins of the oldest leaves (Fig. 1).
Caterpillar feeding damage is similar except that much larger, irregular areas of the oldest leaves are cut out. Often, the midrib of each leaflet is all that remains following heavy feeding by caterpillars, whereas Sri Lanka weevil damage is usually much less severe.
This damage is caused by the Sri Lanka weevil (Myllocerus undatus), a small (1/4 inch) whitish-gray weevil.
Within the United States, this weevil is currently found only in southern and central Florida. It is native to Sri Lanka but is now found throughout India and Pakistan as well.
