It is one of the largest subfamilies of leaf beetles,[1] including more than 500 genera and 7000 species.

Typical coloration for this subfamily of beetles ranges from bright yellow to dark red.

Eumolpinae can be recognized at first sight by their rounded thoraces, more or less spherical or bell-shaped, but always significantly narrower than the mesothorax as covered by the elytra.

Additional features include a small head set deeply into the thorax, and usually well-developed legs.

They generally resemble other Chrysomelidae, but differ in having front coxae rounded and third tarsal segment bilobed beneath.
