Meadow spittlebug, Philaenus spumarius, can be a pest of a variety of ornamental plants particularly herbacious perennials and herbs. Heavy feeding by spittlebugs can stunt plant growth and commonly causes distortion of the new growth on which they feed.

Meadow spittlebugs overwinter as eggs that have been laid on host plants in the fall. Tiny orange nymphs emerge from the eggs in the spring. There are five stages or instars of spittlebug nymphs, which change from orange to yellow to the pale green before the final molt to the adult stage. While feeding, the nymphs produce a foamy spittle or froth that protects them from predators and drying out. Adults are variable in coloring, brown or tan, and often mottled.
