Mine in Aruncus sylvestris, perhaps Agromyza idaeiana?

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.
Best wishes, Niels-Jan Dek

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.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol
