Lilioceris is a genus of leaf beetles within the family Chrysomelidae, notable for their specialized feeding habits on lilies and other related plants. These beetles are relatively small and often brightly colored, typically red or orange with black markings, making them both visually striking and easily recognizable. Found primarily in temperate and tropical regions, Lilioceris species can be significant pests in gardens and agricultural settings, particularly for ornamental plants and lily cultivations. Their life cycle includes egg, larva, pupa, and adult stages, with larvae and adults both feeding on the foliage, which can lead to substantial damage to host plants. The study of Lilioceris is important for developing effective pest management strategies in horticulture and agriculture, as well as for understanding the dynamics of plant-insect interactions.
