Scaeva selenitica can reach a length of 12–15 millimetres (0.47–0.59 in), with a wing length of 10.5–12 millimetres (0.41–0.47 in). These large distinctive hoverflies have sparse, fine light hair. Thorax is shiny black, scutellum is yellowish-green and the abdomen is dark black, The legs are light brown-yellow in the middle, while femurs and feet are darker. The abdomen shows three pairs of yellow comma markings (lunules).
