- These wingless, powdery, and waxy insects (adults and nymphs) are elongate and oval in shape and 1/8-inch long. They are have protrusions all over their body and two longer filaments project from their rear.
- Long-tailed mealybug: long waxy filaments project from the sides of the body and two long filaments (more than half the body length) project from the rear.
- Striped mealybug: two dark longitudinal stripes down the back with many hair-like projections over the dorsal surface.
- Taxus mealybug: four dark longitudinal stripes down the back with 15-17 lateral paired waxy projections.
Biology and Habits:
- Immature (nymphs) overwinter in or under bark
- Adults and immature mealybugs suck plant juice from buds, leaves, twigs, and branches using their piercing and sucking mouthparts.
- There are two to three generations per year.
- Long-tailed mealybug: holly, pyracantha, rhododendron, and yew.
- Striped mealybug: apple, azalea, boxwood, dogwood,hawthorne, holly, magnolia, and mulberry.
- Taxus mealybug: dogwood, maple, rhododendron, and yew
- As mealybugs feed on plant juices they secrete a sugary substance (honeydew) that, as it ages, produces a black sooty mold.
- Damaged leaves become discolored, turning yellow; heavily damaged leaves die.
