Eriococcus azaleae
Pest description and damage Scale insects are small (less than 0.125 inch in length) soft insects that live beneath waxy 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. The immature azalea bark scale insects superficially resemble mealybugs in appearance. Mature female scales are about 0.13 inch in length and appear like white cottony sacs, often located on twigs and stems of azalea, especially in branch axils. Eggs, crawlers, and adults under the whitish cotton are red.
