Wing length 8-11·25 mm. Scutellum yellow. Tergite 2 has large silverish-white to yellowish- white marks (often merged). Tergites 3 and 4 have narrow or absent markings. The male genitalia are figured by Dusek and Laska (1967) . [5] The larva is figured by (Dusek and Laska (1962) [6] See references for determination [7] [8] [9] [10]
The species has a Palearctic distribution from Fennoscandia south to the Pyrenees, from Ireland east through central Europe into Turkey and European Russia, Russian Far East and Siberia and the Pacific coast (Kuril Islands and Japan). [11] [12]
The species' habitat includes Quercus and Fagus forest, riverine gallery forest of Fraxinus and Salix , beside streams, in clearings and along tracks. [13] Flowers visited include white umbellifers, Filipendula , Sambucus and Senecio . [14] The flight period is May to September, with the peak in July and August. The larvae feed on aphids.
Syrphus ribesii is a very common Holarctic species of hoverfly. Its larvae feed on aphids. In common with many other species of hoverfly, males have the eyes meeting on the top of the head, whilst females have their eyes widely separated.
Eupeodes corollae is a very common European species of hoverfly. Adults are 6–11 millimetres (0.24–0.43 in) in body length. Males and females have different marking on the abdomen; males have square commas on tergites 3 and 4, whereas females have narrow commas. Larvae feed on aphids. This species has been used experimentally in glasshouses as a method of aphid control, and to control scale insects and aphids in fruit plantations. They were found to be partial to the fruit, eating more fruit than aphids.
