Host plant.

Cycadaceae: Cycas revoluta (Fig. 1 H, I) (Kato 2001). Wood of Ficus superba (Miq.), Ficus erecta Thunb., Pittosporum tobira (Thunb.), and Boehmeria biloba Wedd. are also used as larval hosts (Coleopterological Society of Japan 1984).

Leaf mines.

Linear mine in a leaf stalk. The adult female bites the lower surface of the leaf stalk and inserts eggs into the scar (Fig. 1 H). The larva mines the woody leaf stalk linearly, but does not enter leaflets. The fully grown larva pupates in the mine (Fig. 1 I).
