Two-Lined Spittlebug Adults: Identification and Control

Half-inch, chocolate-brown bugs with two slim orange stripes across the back are adult two-lined spittlebugs. In spring their nymphs produce telltale frothy "spittle" masses at plant bases. Adults feed on hollies and other plants, sucking sap and causing yellow stippling.

Light infestations rarely need treatment. If damage appears, spray affected plants with a labeled garden insecticide. The photos show adults and nymphs for reference.
