The mealybug is a scale insect.
More Info: Scale insects are homopterous, having piercing, sucking mouthparts used to feed on plant juices, from the family Coccidae. Scale insects have a white waxy coating, which is produced as a byproduct of secreted honeydew.
What Does a Mealybug Look Like?
A female mealybug looks like a small, white oval divided into many sections. Her body is pink, but is covered with a white, waxy substance that she produces. The wax serves to protect her and her young. An adult female mealybug is generally one and a half to three millimeters in length with multiple legs. There are spines at the base of a female mealybug’s flat body. Alternatively, a male mealybug is smaller than the female. A male mealybug also has wings that are flat against its back. Depending on the type of mealybug, males can be brown in color.
What Is a Scale Insect?
A scale insect is any of about 8,000 insect species in the order Hemiptera. Scale insects vary in size and shape, ranging from 1-2mm and oyster-shaped to 1-2cm and reminiscent of a beetle. Most are parasites of plants, leeching sap directly from the plant’s vessels. The females of the species are predominantly immobile; remaining attached to whatever plant they are feeding off of for life. Males have wings but never feed, thus their lifespan never exceeds about two days. Scale insects excrete a waxy defensive coating that resembles fish or reptile scales, making them resistant to pesticides and other bugs.
