Platycheirus rosarum is a species of hoverfly found in the Holarctic realm. Like its close relative Platycheirus granditarsus , it can be found in marshy meadows and ditches; indeed, the two species can often be found together. The flight time is between May and October, though it peaks in abundance in June and July. Like other hoverfly in this genus, its larvae feed on aphids. ^{[1] [2] [3] [4]}
