Apterae are scattered on the undersides of leaves of host plant, with a circle of thin and curved wax filaments along the margin of body and two rather long wax filaments at the hind end of body (Fig. 7). In Japan, apterae occur on undersides of leaves of Quercus throughout the year ( Takahashi 1958).
