Zeugophora chujoi Ohno 1961

Zeugophora chujoi Ohno, 1961 Fig. 2 F – I Host plant. Celastraceae: Euonymus fortunei (Turcz.). Leaf mine. Full-depth linear-blotch mine on the leaf blade and the midrib of a newly-opened leaf (Fig. 2 G – I). The egg is laid in the midrib and the hatched larva enters the midrib and bores into the petiole, leading to leaf abscission from the shoot at the petiole base. Following the leaf fall, the mine diverges from the midrib and expands in the leaf blade, forming a blotch mine. Frass is granular and scattered throughout the mine. The fully grown larva exits the mined leaf, falls to the ground, and pupates underground. Material examined. • 4 adults, Nagao-tôge, Gotenba, Shizuoka Pref., 15-V-2018 (as larva on Euonymus fortunei), emerged on 18-VI-2018 (Fig. 2 F – I).
