Pests in Gardens and Landscapes

Seasonal development and life cycle—Spittlebugs

Adult spittlebugs are inconspicuous. Females lay small eggs in rows in hidden parts of the plant, such as the sheath between leaves and stems. Nymphs undergo about five molts, and may be orange, yellow, or green. More than one nymph may be found in a single spittle mass.
