Sphaeroderma unicolor Kimoto, 1965 Fig. 15 H – L Host plant. Ranunculaceae: Clematis terniflora DC., C. apiifolia DC. Leaf mine. Full-depth linear mine on mature leaf, often adjoining its own trajectory (Fig. 15 L). Frass is linear thread-like, deposited along a side line of the mine. Mining larva is found from late autumn to early winter. 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.
