Eriococcus azaleae
Pest description and damage Scale insects are small (less than 0.125 inch in length) soft insects that live beneath protective wax scales. These insects are often identified by the shape and size of their scales, the description of adult males and females, immature crawler stage, color of eggs, and host plant preferences. Immature azalea bark scales resemble mealybugs in appearance. Mature female scales are about 0.13 inch in length and appear as tiny white cottony sacs, located on twigs, stems and branch axils of host plants. The eggs, crawlers and females beneath these whitish scales are reddish. Hosts include andromeda, azalea, rhododendron, hawthorn, poplar, willow, and most recently blueberries.
