Accurately stating the nature of plant-insect interactions is essential for our understanding of the insect, its role in the ecosystem, and the evolution of the interaction. The term “host plant” is used to denote a special connection between a given insect and a plant, but host plant is also a jargon term lacking precise meaning. In the case of Languria mozardi Latreille 1807 (Coleoptera: Erotylidae: Languriinae), the authors examined 17 manuscripts and found 48 plants, within seven families, identified as host plants for L. mozardi. Of these 48 plants, 13 are confirmed by the literature as developmental hosts. Many inadequately documented L. mozardi-plant associations have been referenced repeatedly in the literature, and the authors' aims are to clarify these relationships.
