Description

The wings are 8-9.5 mm in length. The scutellum is shiny. The face is covered with pale dust (there is a narrow black stripe here in worn specimens) on the lower part. The apical half of the arista is bare and the basal half is very short-haired. The eyes have pale yellow hairs. The female eyes are separated. The tibia are pale black on the basal quarter or less. Tibia 2 is very pale.[2][3][4][5] The male genitalia are figured by Hippa et al. (2001).[6] The larva is figured by Hartley (1961).[7]

Distribution

Eristalis abusiva occurs from Palaearctic Fennoscandia and the Faroes (Jensen, 2001) south to North France, from Ireland eastwards through Europe and Russia to the Pacific coast.[8][9]

Biology

The habitat is wetland, coastal fen and salt-marsh, marsh and fen, raised bog and cutover bog.[10] Flowers visited include yellow composites, white umbellifers, Calluna vulgaris, Caltha, Cirsium, Erica, Potentilla erecta, Ranunculus, Rubus fruticosus, Salix repens, Stellaria, Spartina.[11]

The flight period is beginning May to mid October. The larva is aquatic.
