Eupeodes corollae is a very common European species of hoverfly. Adults are 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.
E. corollae is found across Europe, North Africa and Asia. Adults are often migratory.
