(Fig. 2)

Larva. Probably early instar (Fig. 2A): Head pale olive; trunk creamy white. Middle instar (Fig. 2B–C): Head pale olive; trunk pale greenish, each segment with small black spots dorsolaterally and laterally. Late instar (Fig. 2D): Head olive, with broad blackish band along midline; trunk pale greenish, each segment with small black spots dorsolaterally.

Material examined. HONSHU: Tochigi Pref.: 1Ə (Fig. 2F), Nakagawa, Koisago, 36°47′N 140°11′E, coll. larva on Rubus trifidus, 23. V. 2021, mat. 14. VI., em. 19. IV. 2022, S. Ibuki .

Host plants. Rosaceae: Rosa onoei Makino var. onoei (Okutani, 1970; Inomata, 1989). Rubus trifidus Thunb. (new record).

Life history. In Nakagawa, Tochigi Prefecture, Ibuki found a middle instar larva feeding on Rubus trifidus on May 23, 2021, which matured on June 14 and entered the soil. A male adult emerged on April 19, 2022. The larva was a solitary leaf-feeder and stayed coiled at rest (Fig. 2E). This species is regarded as univoltine.

Remarks. As a host plant of this species, Okutani (1970) first recorded Rosa sp. based on the rearing result of Ryoichi Inomata, who (Inomata, 1989) himself recorded lYabuibara, Rosa Luciae Franch. et Rochebr. z (= Rosa onoei var. onoei) later. This is an oligophagous species feeding on Rosa and Rubus . No information about the larva and life history of this species has been published.
