Description
Cabbage tree mealybugs are small flat-bodied insects that live at the base of cabbage tree leaves. The adult female is oval shaped and about 4 millimetres long and 2 millimetres wide. Males are smaller in size, about 2 millimetres long and have wings. The body of a mealybug is orange-pink, and covered with a powdery white wax, which the bug produces. Mealybugs also cover the areas they live in with the white wax, which assists with visual detection.
