Chalcomeratini

Chalcomeratini is a tribe of leaf beetles belonging to the subfamily Eumolpinae. This group is characterized by a generally metallic coloration and a wide geographic distribution, found across various continents. Members of Chalcomeratini are primarily herbivorous, feeding on the leaves of a range of plants. Their specific host plants can vary significantly depending on the species and geographic location.

The taxonomy of Chalcomeratini has undergone revisions, with some genera previously placed within this tribe now being reclassified. However, the core group remains a significant assemblage of Eumolpinae. Key genera within Chalcomeratini include Chalcopercna, Chrysomelopsis, Clypeolala, Colaspoides, Colasposoma, Eusperche, Falsocolasposoma, Falsogrethera, Falsomadotrogus, Pseudochalcopercna, Pseudocolasposoma, Sphaenothecus, and Stenopaltella.

While not as extensively studied as some other insect groups, Chalcomeratini beetles play a role in their respective ecosystems as herbivores. Their impact on plant life can range from minimal to significant, depending on population densities and the susceptibility of their host plants. Further research is ongoing to better understand the diversity, ecology, and evolutionary relationships within this beetle tribe.
