Remarks
- Systematics: The bark form of Chionaspis betulae resembles C. acericola, but differs as follows: median lobes of C. acericola symmetrical and laterally notched, in C. betulae asymmetrical and not notched; gland spines absent on the 1st abdominal segment in C. acericola, always present in C. betulae; several small submedian macroducts on abdominal segments 3 and 4, these lacking in C. betulae. The leaf form of C. betulae resembles the leaf form of C. gleditsiae. It differs in having fewer (less than 10) dorsal macroducts, while C. gleditsiae reportedly has more than 20 (Tippins & Beshear, 1970b).
- Structure: Adult female spindle shaped, margin of free abdominal segments lobed laterally, length on slide 0.9 mm (Tippins & Beshear, 1970b).
- Biology: Chionaspis betulae has a bark form and a leaf form (Tippins & Beshear, 1970b).
- General Remarks: Best description and illustration by Tippins & Beshear (1970b).
