5-6mm. Argyra species can be recognised by the row of 3 or more bristles on the outer face of the hind coxa (except A. vestita which has 2). Males are also noticeable in flight by their silvery appearance - a feature that depends on the angle of light.

Females: The thorax is metallic green and the abdomen bronze-green with pale lateral patches on tergites 2-4. The face is white.
