Hello,
here I am very unsure. Is it the mine of Phytomyza eupatorii?

Plant: Eupatorium cannabinum
25.09.2019
forest path near Furth im Wald, Bavaria, Germany

Regards
Ingrid

Hi Ingrid, not sure but it may be Chromatomyia cf. syngenesiae "frass in isolated grains"...:

Hi Eric,
Chromatomyia cf. syngenesiae looks much better.
The isolated grains unsettled me at Phytomyza eupatorii.

Thank you very much!

Greetings
Ingrid
