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 Ingrid Altmann attached the following image:  [255.64Kb] |

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. |
