Fig. 1 G – I

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 ).

Material examined.

• 5 adults, Haneji , Nago, Okinawa Is., Okinawa Pref., 1-II-1998 (as larva on Cycas revoluta ), emerged on? - V- 1998 ; 2 adults, Hedo , Kunigami, Okinawa Is., Okinawa Pref., 1-II-1998 (as larva on Cycas revoluta ), emerged on 20-III-1998 .
