Zeugophora varipes (Jacoby, 1885)

Fig. 2 R, S

Host plant.

Symplocaceae : Symplocos coreana (H. Lev.) , S. sawafutagi Nagam.

Leaf mine.

Full-depth linear-blotch mine on young leaf (Fig. 2 S ). The egg is laid in the leaf blade, and the hatched larva constructs linear mine along the leaf margin, then gradually expands the mine. The mine is wider than the width of the larva. Frass is granular, scattered throughout the mine. The fully grown larva exits the mined leaf, falls to the ground, and pupates underground.

Material examined.

• 1 adult and 5 leaf mines, Iyari , Ômachi, Nagano Pref., 5-V-2016 on Symplocos sawafutagi (Fig. 2 R, S ) ; 6 adults, Omotsubo , Okayama Pref., 27-V-1993 (as larva on Symplocos coreana ), emerged on 20–24-VI-1993 .
