Fig. 2 J – M

Host plant.

Celastraceae: Euonymus carnosus Maxim., E. japonicus Thunb.

Leaf mine.

Full-depth linear mine on the newly-opened leaf (Fig. 2 K – M). The egg is laid near the leaf margin and the hatched larva mines along the leaf margin, slowly expanding the mine. Frass is thread-like, deposited somewhat to one side of the center. The fully grown larva exits the mined leaf, falls to the ground, and pupates underground.
