Ground Pearls

Adult female Ground Pearls have soft, pink, pear-shaped bodies whereas males are tiny, pinkish-white, gnat-like insects. While only female Ground Pearls are considered lawn-destroying insects (the males cause no damage to grass), both sexes of this lawn pest are rarely seen. Newly hatched nymphs disperse in the soil and secrete a waxy material that hardens into a shell or cyst. The cyst resembles a miniature pearl with its color varying from pearly white to yellowish or purple—hence the name. There is some evidence that a small portion of these cysts can remain dormant in the soil for several years. Signs of Ground Pearl damage to lawns include unsightly, irregular patches of grass that will eventually die out. These lawn pests suck out plant fluids and deposit a toxic salivary substance that causes your grass to turn yellow and then brown. This damage is most often seen during dry conditions. Once lawn damage caused by Ground Pearls is extensive enough to kill your grass, it rarely grows back. Instead, weeds will replace the damaged areas of your lawn—a final insult from these lawn-destroying insects.
