Adults are about an inch long, with gray wings, black spots, and red and black underwings. Nymphs are black with white spots, turning red before maturing. They use needle-like mouthparts to drain sap from plants.
To combat them, squash adults and nymphs, and destroy egg masses, which resemble gray mud smears. Scrape eggs into a bag with alcohol or hand sanitizer to kill them. Acting quickly can help protect our environment from further harm.
