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 View Figure 2 ). 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.
