Description of last instar larva (Figs 3E; 12C–I; 13E). Diagnosis. The last instar larva is easily distinguished from larvae of other Chrysolina species in Japan by the following characters: body sparsely and entirely furnished with tubercles (Fig. 12C); tarsungulus furnished with tooth (Figs 12D, 13E). Coloration. Head black with copper sheen except for testaceous anterior margin of frons, clypeus, labrum and mouthparts. Body grayish yellow without blackish brown tubercles and spiracles (Fig. 3E).
