The Green Metalwing is a conspicuous medium sized Demoiselle. The body is shining metallic green in both sexes and it has long legs. The male has characteristic metallic green hindwings and hyaline forewings. The female has hyaline wings with pale brownish veins.
It is a quite common species. It prefers rather open, swift running streams in forested areas, both in lowlands and in mountains. It may be confused with Matrona basilaris which has metallic blue inner wings instead of green.
