The normal length wings are usually hyaline. The wing length is 4 ·5-6·75 mm.,body length is 5.0 to 7.0mm.A very variable species. See references for determination. [1] [2] [3] [4] [5]

Flowers visited include Caltha , Cirsium arvense , Leontodon , Leucanthemum , Menyanthes , Prunus spinosa , Ranunculus , Salix , Senecio , and Taraxacum . It flies from April to October. The larva feeds in the stems of Achillea, Matricaria and Sonchus oleraceus and in the involucre of Tragopogon . [8]

<i>Eupeodes corollae</i> Species of fly

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.
