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).
Greetings, Eric

Chromatomyia syngenesiae is also known on this host ( and forms identical mines to horticola, adults must be reared.
