Lema
Lema is a genus of leaf beetles in the family Chrysomelidae, subfamily Criocerinae, established by Fabricius in 1798. The genus includes species that feed on plants in the nightshade family (Solanaceae), with some species such as Lema daturaphila (three-lined potato beetle) known as agricultural pests. Members of this genus have evolved physiological adaptations to tolerate toxic alkaloids present in their host plants.
