Hi,
ID possible?
Photo on Finland Kokkola 19 July 2021.

Could this be the mine of Chromatomyia?
Thank you in advance for any help in identification,
Pentti

Hi Pentti, I think you are right with Chromatomyia and probably it's the polyphagous C. horticola (we can see the frass in isolated grains, but other C. do it the same way).

Chromatomyia syngenesiae is also known on this host (https://agromyzidae.myspecies.info/node/1382) and forms identical mines to horticola, adults must be reared.

Thank you both very much!
