Remarks

• Systematics: Cooley (1899) states: "This species has no near relatives so far as is known, the only insect resembling it being Chionaspis americana, which also has the inner edges of the median lobes fused together. The two species can be readily distinguished by the lobes, C. americana being distinctly notched, while in C. caryae they are entire."
• Structure: Scale of female irregular, oystershell-shaped, convex, dirty white, 1.5-2 mm long, exuviae brown. Female elongate, spindle-shaped, segments produced laterally, 1.0 mm long on slide (Kosztarab, 1963).
• Economic Importance: In some sections of the United States, Chionaspis caryae has proven injurious to young hickory trees, malforming the branches and twigs (Hollinger, 1923). Miller & Davidson (1990) list this insect as a pest.
• General Remarks: Descriptions and illustration by Cooley (1898), Liu et al. (1989).
