A leaf mining fly whose larvae mine the leaves of various members of the Buttercup family of plants.  In this species the mine is linear, whitish, with frass in widely spaced grains.

See the National Agromyzidae Recording Scheme webpage for this species for further details of puparium and adult insect.

Phytomyza ranunculi mines are similar but the frass grains are more closely grouped.
