Description: The adults reach 10–12 millimetres (0.39–0.47 in) of length, with a wingspan of 25–30 millimetres (0.98–1.2 in). The basic coloration of the body is green. Wings are blue-green with black veins. Black markings are present on the head, including one with X form between the antenna, the thorax and below the abdomen. The second antennal segment is black.

Also larvae are predators, mainly feeding on Aphididae and Coccidae species. The adult insects hibernate in winter. They can be encountered from May through August.
