Agaristes

Agaristes is a genus of beetles in the family Chrysomelidae, commonly known as leaf beetles. The genus was described by Louis I. L. Germain in 1835. Species within Agaristes are typically found in South America, with a notable concentration in Brazil and Argentina.

These beetles are characterized by their often brightly colored and metallic elytra, which can vary in patterns and shades depending on the species. The larvae and adults of Agaristes beetles are herbivores, feeding on various plant species, particularly those belonging to the family Solanaceae. Their diet can sometimes lead to them being considered agricultural pests, though their impact varies regionally.

Research into Agaristes species often focuses on their taxonomy, ecological roles, and evolutionary relationships within the Chrysomelidae family. Due to their striking appearance, some species have also been subjects of interest in entomological collections and amateur observations. The genus Agaristes is part of a larger subfamily, Chrysomelinae, which contains a vast diversity of leaf-feeding beetles worldwide.
