Host plants

This species has been recorded from Quercus (Fagaceae) and Prunus (Rosaceae) (Murayama 1954).

Remarks

Wood and Bright (1992) erroneously reported this species from ‘Pinus maximowiczii’. Murayama (1954) reported the species from Prunus maximowiczii, Korean cherry, thus the record from Pinus is incorrect.
