Mesosemia

Mesosemia is a genus in the butterfly family Riodinidae present only in the Neotropical realm.

Also here there is in most of the species almost exactly above the middle of the forewing a large eyespot which often exhibits two or three white pupils, and where it is absent, one mostly finds yet its traces in the shape of a small central shade or minute cloud.

The Mesosemia differ from the Eurybia by their smaller heads, the shorter antennae, the borders of the forewings being generally slightly curved, the short abdomen mostly not reaching as far as the anal angle, the longer hindwings being often geniculate (knee like) in the middle of the distal margin, or angularly protended (held out).

Then they perform jerky movements on the leaves, stretching the antennae straight forward, placing the hindwings flat on the leaf and slightly raising the forewings.

In this manner they hasten from one leaf to another, from one branch to another, more jumping than flying, as Fassl expresses himself.
