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 yel- low; trunk pale green yellow. Mature larva (prob- ably 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 presum- ably 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.
