Sphaeroderma ohkuboi Chûjô, 1940

Fig. 15 S – Z

Host plant.

Ranunculaceae : Cimicifuga japonica (Thunb.) , C. biternata (Siebold et Zucc.) , C. simplex Wormsk.

Leaf mine.

Full-depth linear mine on the mature leaf (Fig. 15 V – X, Z ). Frass is dark pasty, deposited as a wide band along middle line of the mine. The fully grown larva exits the mined leaf in autumn, falls to the ground, and pupates underground. The pupa hibernates under the ground, and the adult emerges the next spring.

Material examined.

• 1 adult and several leaf mines, Mt. Nakatsu-myôjin , Niyodogawa, Kôchi Pref., 6-X-2020 on Cimicifuga japonica (Fig. 15 S – X ) ; 1 adult, Shirahone , Matsumoto, Nagano Pref., 15-X-2013 (as larva on C. simplex ), emerged on? - V-2014 (Fig. 15 Y, Z ) ; • 1 adult, Toyohara , Nasu, Tochigi Pref., 14-IX-2003 (as larva on C. simplex ), emerged on 3-V-2004 .
