Millomeris

Millomeris is a genus of small, iridescent beetles belonging to the family Chrysomelidae, commonly known as leaf beetles. These beetles are characterized by their striking metallic coloration, which can shift in hue depending on the angle of light. Species within Millomeris are typically found in tropical and subtropical regions, inhabiting areas with abundant vegetation.

The diet of Millomeris beetles primarily consists of plant matter. Adults and larvae feed on the leaves, stems, and sometimes flowers of various plant species. Their feeding habits can sometimes lead to them being considered pests in agricultural settings, though their economic impact is generally limited. Reproduction involves the laying of eggs, usually on the host plant. The larval stage is characterized by significant growth and consumption before pupation and emergence as an adult beetle.

While visually distinctive, Millomeris species are not extensively studied in terms of specific ecological roles or detailed life cycles compared to more common beetle genera. Research often focuses on their taxonomic classification and distribution. Their iridescent appearance is a result of structural coloration, a phenomenon where microscopic structures on the cuticle interact with light to produce color. This adaptation may play a role in camouflage, species recognition, or thermoregulation.
