Fig. 2 N – Q

Host plant.

Celastraceae: Celastrus orbiculatus Thunb., Euonymus alatus (Thunb.), E. fortunei (Turcz.), E. japonicus Thunb., E. macropterus Rupr., E. melananthus (Thunb.), E. oxyphyllus Miq., E. tricarpus Koidz., E. sieboldianus Blume. Tripterygium regelii is also recorded as a host by Takemoto (2019).

Leaf mine.

Full-depth linear-blotch mine on newly-opened leaf (Fig. 2 O – Q). The mine often covers the whole area of the leaf causing deformation of the leaf, and the larva moves to another unmined leaf. Frass is thread-like and meandering, deposited along the center of the mine. The fully grown larva exits the mined leaf, falls to the ground, and pupates underground.
