The Orange-spotted Emerald is about 53 millimetres (2.1 in) long. It has bright green eyes and a bronzy-green body with yellow spots along the top of the abdomen. The last segment of the abdomen (S10) has a prominent yellow mark on the upper surface.^[3]

The species occurs in much of Europe but is regionally extinct in the Netherlands and the United Kingdom. Its habitat is slow flowing streams, pools and ponds.^[1]
