The life-history of the willow spittlebug Aphrophora pectoralis on two willow species, Salix miyabeana and S. sachalinensis, was studied in Hokkaido, northern Japan. A. pectoralis has a univoltine life-cycle overwintering in the egg stage. There were no significant differences in the duration of nymphal stages between the two willow species. Mating and oviposition occurred from early August to mid-October, and at the start of this period adult females had about 10 mature oocytes. Thereafter, the number of mature oocytes increased, peaking in late September. The cumulative number of egg masses per shoot on S. sachalinensis was significantly greater than that on S. miyabeana. This result suggests that female spittlebugs prefer S. sachalinensis to S. miyabeana as an oviposition plant despite no difference in the growth performance between the two host species.
