Entiminae

Entimines are commonly encountered in the field, including urban environments, and abundant in entomological collections.

There are over 12,000 described species in the Entiminae subfamily worldwide, distributed in over 1,370 genera,[1] which total nearly 14,000 by more recent counts.

[3] In general, entimines tend to feed on a broad range of plants (polyphagous), but there are instances of oligophagy.

They feed on monocotyledoneous and a broad range of dicotyledoneous plants, including members of the families Fabaceae, Malvaceae, Rutaceae, Solanaceae, and many more.

Entimines may lay eggs loosely on the substrate, or in clusters glued onto the vegetation[5] and do not use their rostrum to prepare their oviposition site.
