Yellow, elliptic eggs are deposited in the leaf axils and on the petiole (Doguet, 1994a). Full depth corridor, widening into a blotch. Frass in black threads. Larvae may leave the mine and restart elsewhere. Pupation outside the mine. Neither mine nor larva can be distinguished from those of M. obtusata, but chrysanthemi prefers dry habitats. Beetle metallic green.
