Could this be the mine of Phytomyza ranunculi alternative Phytomyza ranunculivora? Is it possible to determine? On Ranunculus sp. in vet spruce forrest. 4.09.2021 north of Uppsala, Sweden.
Thank you in advance for any help in identification,
Adam

Thank you very much. What features allow distinguishing of mines of Phytomyza ranunculi and Phytomyza ranunculivora?

The frass in ranunculi is very closely spaced, as in your image. In ranunculivora, the frass is much more widely spaced.
