Systematics: Chionaspis kosztarabi is close to C. gleditsiae, but distinguishable both in the adult female and in the 2nd stage male. As adult females, they are distinguishable by the ventral microducts of the prosoma: in C. gleditsiae, these microducts are numerous in 2 groups around the anterior spiracle, whereas in C. kosztarabi such groups are absent. In the bark-feeding forms, C. kosztarabi has submedian dorsal macroducts which are always present on the 4th and 5th abdominal segments, whereas in C. gleditsiae they are usually absent on the 4th segment. In C. kosztarabi, the basal zygosis of the median lobes is distinct, extending anteriorly beyond the bases of the lobes, whereas in C. gleditsiae its barely prominent (Takagi & Kawai, 1967).
Structure: Eggs are pale orange or light yellow, elliptical (Willoughby & Kosztarab, 1974).
Biology: Chionaspis kosztarabi is bivoltine in Virginia, overwintering as mature fertilized females. Eggs were deposited in the spring and were present through the last week of June. Crawlers were first present in early June, continuing through the first week of July (Willoughby & Kosztarab, 1974).
