Zeugophora unifasciata (Jacoby, 1885)

Fig. 2 A, B

Host plant.

Celastraceae : Euonymus sieboldianus .

Leaf mine.

Upper-layer linear mine on mature leaf (Fig. 2 B ). The egg is laid in the leaf blade and the hatched larva construct slightly meandering mine. Width of the mine is slightly wider than the width of the larva. Frass is thread-like, deposited along the meandering trajectory. The fully grown larva exits the mined leaf, falls to the ground, and pupates underground.

Material examined.

• 5 adults, Hirayu-tôge , Takayama, Gifu Pref., 6-IX-2019 (as larva on Euonymus sieboldianus ), emerged on 6–7-X-2019 (Fig. 2 A, B ) ; • 1 adult, Toyohara , Nasu, Tochigi Pref., 2-VII-2022 (as larva on E. sieboldianus ), emerged on 3-VIII-2022 .
