All photographed by Ibuki. 1 ˂, Nakagawa, Wami, 33°46′N 140°10′E , coll. larva ( Fig. 2G ), on Sanguisorba officinalis , 20. IX. 2015 , mat. 21. X., em. 16. XII. 2015 , S. Ibuki ; 1 ˂, same data but coll. larva, 25. IX. 2015 , mat. 14. X., em. 16. XI. 2015 . Larva . Early or middle instar ( Fig. 2G ): head pale gray; trunk and legs creamy white. Late instar ( Fig. 2H, J ): head pale pink; trunk and legs pale creamy white, with dorsal region pale greenish gray; thoracic legs tinted with pink. Mature larva ( Fig. 2I ): similar to late instar; head more yellowish. Host plants. Rosaceae : Rosa spp. ( Okutani, 1967b ), Fragaria × ananassa (Weston) Duchesne ex Rozier ( Okutani, 1967b ), Sanguisorba officinalis L. (new record). Life history . This is a multivoltine species. The larva is solitary, though a few larvae may occur on the same leaf ( Fig. 2G ). The larva has an extra molt on maturation and enters a rotten wood, not soil, to make a cell for diapause ( Kondo, 1969 ). Remarks . Okutani (1959) described the larva of this species as Emphytus albicinctus Matsumura and Kondo (1969) published his observations on the life history of this species.
