In February 1976, first instar nymphs of a mealybug were found overwintering in bark crevices of cherry trees at Penticton, B.C. As these were much smaller than and distinctive from overwintering second and third instar nymphs of the apple mealybug, Phenacoccus aceris Signoret, which were present in large numbers, they were collected and reared to the adult stage on small cherry trees in a greenhouse. Mature fernales were identified by Dr. W. R. Richards, Biosystematics Research Institute, Ottawa as the Comstock mealybug, Pseudococcus comstocki (Kuwana).
