Cheilosia albitarsis/ranunculi agg.
Sarah Loving on iSpot, one of several people to help identify this insect makes the point that "Cheilosia albitarsis/Cheilosia ranunculi (associated with buttercup, around from April) ... the two species can't be separated without microscopic examination." Therefore, I'm treating them as an aggregate on this website.
