At one end is the pale yellow cast skin of the crawler stage. Adult males are tiny insects resembling gnats with four eyes and a tiny waxy tail filament. Little is known of the biology of juniper scale insects. If they behave like other armored scales, these scales hatch from eggs laid by the mother scale under her armor. The tiny crawlers emerge to crawl about seeking a suitable place to feed.
Males emerge from the male armor and seek females with which to mate.
The males soon die. Females soon lay eggs for another generation. After laying eggs, the females die. They are found on the needles and bark of Cedrus, junipers, cypresses, spruce and Leyland cypress. Because they are so small, juniper scales are easily overlooked.
