Fig. 8 A – H

Host plant.

Polypodiaceae : Lepisorus miyoshianus (Makino) ., L. onoei (Franch. et Sav.) , L. thunbergianus (Kaulf.) , Pyrrosia linearifotia (Hook.) and Lemmaphyllum microphyllum C. Presl. are reported as adult’s host plants by Suzuki et al. (2008).

Leaf mine.

Upper-layer linear-blotch mine on mature leaf (Fig. 8 B, F, G ). The fully grown larva (Fig. 8 H ) exits the mined leaf, falls to the ground, and pupates underground.

Material examined.

• 3 adults, Mt. Shizuhata , Aoi-ku, Shizuoka Pref., 27-VII-2017 (as larva on Lepisorus thunbergianus ), emerged on 12–18-IX-2017 (Fig. 8 A, B ) ; • 1 adult on L. onoei , Shôji-ko Lake , Fuji-kawaguchi-ko, Yamanashi Pref., 8-IX-2019 (Fig. 7 C ) ; • 2 adults, Shimo-shimizu , Kiso-fukushima, Nagano Pref., 7-VIII-2011 (as larva on L. miyoshianus ), emerged on 4-IX-2011 (Fig. 7 D – H ) .
