Sphaeroderma uenoi Takizawa, 2021

Fig. 15 M – R

Host plant.

Ranunculaceae : Clematis apiifolia , Clematis terniflora .

Leaf mine.

Full-depth linear mine on mature leaf (Fig. 15 R ). Frass is linear thread-like but intermittent. The fully grown larva exits the mined leaf in early winter, falls to the ground, and pupates underground. The pupa hibernates under the ground, and the adult emerges the next spring.

Material examined.

• 2 adults and several leaf mines on Clematis terniflora , Kizu-gawa , Kusauchi, Kyôtanabe, Kyoto Pref., 11-X-2022 (Fig. 15 M – Q ) ; many leaf mines on Clematis terniflora , Iwakura , Sakyo, Kyoto Pref., 20-XII-2023 (Fig. 15 R ) .
