Hello,
could this be the mine of Agromyza idaeiana?
Host: Aruncus sylvestris
June 16, 2022, forest path near Furth im Wald, Bavaria, Germany.

Regards
Ingrid

I have always been told that agromyzid mines have the frass alternating on the different sides of the mine and lepidopteran mines have the frass in a median line...

That is not always the case Paul. Actually it looks like a Diptera mine to me, although I can not explain why. Bad answer, I know. The frass looks just different in Lepidoptera, I think. Could be Agromyza spiraeoidearum, which is known from this host plant.

Hello Paul and Niels,
I don't know of any lepidopteran that have mines in Aruncus.
Agromyza spiraeoidearum looks good. I just read in the Book: Hering - Bestimmungstabellen der Blattminen von Europa: First feces in grains in lines on the mine sides, later irregularly scattered.
