Epistrophe flava belongs to the subfamily Syrphinae, tribe Syrphini.
Scandinavia south to the Pyrenees and from Belgium eastwards through central and southern Europe (Spain, Italy) into European parts of Russia; through Siberia to the Pacific coast.
Deciduous forest.
Epistrophe flava has a body length of 11 - 14 mm. The only slightly shiny thorax has two indistinct gray longitudinal stripes in the front half. On the abdomen there are 2 large spots on the 2nd segment and 2 broad bands on the 3rd and 4th segments. The face is yellow, antennae are reddish brown. The legs are yellow, only the hind feet are black.
There are some similar epistrophe species, especially Epistrophe diaphana, which has black antennae.
Epistrophe flava flies from May to June and in July at higher altitudes.
Larvae of the species have been found in aphid colonies on Cirsium and Cichorium and on aphid galls on apple (Malus). The young larvae hatch about 5 days after oviposition and develop within 2 - 3 weeks. Afterwards the adult larvae go into a long diapause and pupate only in the spring of the following year. About 15 days after pupation the next generation hatches.
Epistrophe flava = Epistrophe melanostomoides sensu van der Goot (1981)
