Taxonus japonicus Takeuchi, 1929
Japanese name: Bara-kuro-habachi
(Fig. 13)
Larva. Early or middle instar (Fig. 13A): Thinly covered with white bloom; head pale yellow; trunk pale green yellow. Mature larva (probably after extra molt) (Fig. 13B): Head yellow; trunk green yellow, with spiracles black; thoracic legs pale greenish gray.
Material examined. HONSHU: Tochigi Pref.: 1$, Nakagawa, Wami, 36°47′N 140°10′E, coll. larva on Rosa multiflora, 31. V. 2021, mat. 20. VI., em. 12. IV. 2022, S. Ibuki (Fig. 13) .
Host plants. Rosaceae: Rosa multiflora Thunb. (new record), R. onoei Makino var. onoei (Okutani, 1967) .
Remarks. The larva of this species presumably has an extra molt, because the mature larva does not have white bloom. Taxonus minomensis (Takeuchi, 1929) is also known to be associated with Rosa (Okutani, 1967) . Its larva has not been described.
