Zygogramma signatipennis
Zygogramma signatipennis is a leaf beetle in the family Chrysomelidae found in Mexico. The species has been documented feeding on acahual plants (Tithonia tubaeformis, Asteraceae), causing moderate to severe defoliation damage specifically to this host. Research suggests it shows greater feeding preference for plants in the vegetative stage and has been proposed as a potential biological control agent for management of T. tubaeformis as a weed. The species was originally described by Stål in 1859.
