Classification:

Chrysotoxum fasciatum belongs to the subfamily Syrphinae, tribe Syrphini.

Distribution:

Fennoscandia south to the Pyrenees and northern Spain; from Ireland eastwards through northern and mountainous parts of central and southern Europe (northern Italy, the former Yugoslavia, Bulgaria) into European parts of Russia; through Siberia from the Ural to Kamchatka; Japan.

Habitat:

Humid deciduous and coniferous forests, edges of raised bogs, also in the subalpine zone.

Description:

Chrysotoxum fasciatum has a body length of 9 - 12 mm. The abdomen of the hairy fly is short and arched. In addition to the broken yellow stripes on the abdomen segments the segments 3 and 4 have a yellow stripe on the trailing edge, which reaches the lateral seam. The broken stripes on the abdomen segments 3 and 4 do not reach the lateral seam. On the yellow scutellum there is a brown spot, which can be more or less pronounced. The 3rd antenna segment is longer than the 1st and 2nd together.
There are a few similar, difficult to distinguish Chrysotoxum species.

Biology:

Adults fly from May to September in two generations. They visit a wide range of flowers like yellow composites, white umbellifers, Calluna, Leucojum aestivum, Luzula sylvatica, Potentilla erecta, Ranunculus, Frangula alnus, Ligustrum, Rubus fruticosus, Rubus idaeus, Salix repens and Sorbus aucuparia.

Annotation:

Chrysotoxum arcuatum (Linnaeus, 1758) = Chrysotoxum fasciatum (Müller, 1764)
