Cycas revoluta, commonly known as the sago palm, is a gymnosperm of the family Cycadaceae, native to Asia and widely cultivated for its ornamental value. Despite its palm-like appearance, it is unrelated to true palms (Arecaceae). Known for its hardiness and tolerance to mild cold, C. revoluta is frequently used in landscaping and bonsai, and in some areas, as a source of sago. The species is vulnerable to several insect pests such as spider mites, scale insects, mealybugs, aphids, red palm weevils, caterpillars, and various beetles that damage its foliage and reduce plant vigor. Notably, beetles also play a dual role as both pests and potential pollinators. Among them, Lilioceris species have been observed feeding on Cycas species in New Guinea and Thailand. In 2024, Lilioceris sp. (Coleoptera: Chrysomelidae) was documented for the first time infesting C. revoluta in Assam, India. The larvae caused papery leaf damage and bored into the leaf stalks before pupating in soil cocoons. Adult beetles, identifiable by their bright red coloration, further damaged the foliage. This finding marks a new pest record for C. revoluta and highlights the need for targeted pest management strategies for this economically and horticulturally significant species.
