Fig. 14 M – Q

Host plant.

Ranunculaceae : Clematis tashiroi Maxim. The host plant record of Smilax spp. by Takizawa (2021) is uncertain.

Leaf mine.

Full-depth linear mine on mature leaf (Fig. 14 N – P ). Frass is granular, deposited as a band along middle line of the mine. The fully grown larva (Fig. 14 Q ) exits the mined leaf in early winter, falls to the ground, and pupates underground.

Material examined.

• 6 adults, Funaura , Iriomote Is., Yaeyama, Okinawa Pref., 6-III-2019 (as larva on Clematis tashiroi ), emerged on 20-IV-2019 (Fig. 14 M – Q ) .
