Young larvae are yellow but darken with age to yellow-brown to grey, usually with dark and orange stripes. Larvae reach 13 mm in length. Moths have grey forewings with a transverse two-tone pale/dark band. Moths rest with their wings folded back along the body and are only 8 mm long.
Damage: Holes made in adzuki pods may let in water and increase seed weathering. Leaf webbing is unlikely to affect yield.
