Systematics: Ferris (1937) states that Chionaspis acericola is quite distinct. It can be told from C. gleditsiae and C. parkii (= C. platani) by paying careful attention to the degree of fusion of the median lobes, the nature of their zygosis and the distribution of the dorsal ducts.
Structure: Male scale small, slender, more or less oval, exuvia terminal and light brown, about one third the length of the female scale. Female scale is whitish, often partly covered with extraneous adhesive material, about 2 mm long; more or less broadly pyriform to irregular in shape; flat and rather thin; exuviae relatively large (Hollinger, 1923).
Biology: Chionaspis acericola overwinters in egg stage and there were unhatched eggs under female scales as late as April 24, 1960 (Kosztarab, 1963).
