Systematics: Quernaspis insularis is separable from Q. quercus in having a more acute pygidium, fewer dorsal submedian macroducts on abdominal segments 3-5, and usually fewer submarginal macroducts on abdominal segment 4. It is easily distinguished from Q. quercicola, by the fused median lobes. In Q. quercicola, the median lobes are clearly separated on the apical half (Takagi & Howell, 1977).
Structure: Female scale white, elongate, narrow anteriorly widening posteriorly, about 1.5 mm long. First exuviae terminal. Adult female body fusiform, widest across abdominal segments 1-2. Prepygidial abdominal segments lobed laterally. Pygidium broadly triangular, margins subtending an angle of about 100° or less (Takagi & Howell, 1977).
General Remarks: Detailed description and illustration by Takagi & Howell (1977). Description and illustration of first instars by Howell (1981a).
