Summary

Eumolpinae is a diverse subfamily of leaf beetles, with around 150 species in 25 genera in North America and approximately 5,000 species worldwide across 420 genera. They are characterized by their distinct oval shape, coloration, and specific morphological features that differ from other Chrysomelidae.

Physical Characteristics

Subglobose to oblong oval, small to medium beetles measuring up to 10 mm in size. Typical coloration ranges from bright yellow to dark red; many species are iridescent or metallic blue or green.

Identification Tips

Eumolpinae can be recognized by their rounded thoraces that are narrower than the mesothorax covered by the elytra, a small head deeply set into the thorax, and well-developed legs. They have front coxae that are rounded and a deeply bilobed third tarsal segment.

Habitat

Numerous in tropical and subtropical regions, particularly in South America, temperate and tropical Africa, Australia, New Guinea, Fiji, and New Caledonia.

Distribution

Worldwide, with high species richness in the tropics and subtropics, particularly in South America, tropical Africa, and New Caledonia.

Diet

Known larvae are subterranean root feeders; adults typically feed on leaves.

Evolution

The subfamily Eumolpinae is one of the largest subfamilies of leaf beetles, evolving from early chrysomelid ancestors.
