White Prunicola Scale
What was formerly considered to be a single species of scale known as the white peach scale, has been determined to actually involve two species, one commonly known as the white peach scale, Pseudaulacaspis pentagona, and the other, Pseudaulacaspis prunicola, with the suggested common name of white prunicola scale (WPS). The WPS is the species found on Long Island, whereas white peach scale is more southern in its geographic distribution.
