Aulagromyza cornigera

Aulagromyza cornigera
Sharon, Litchfield County, Connecticut, USA
May 11, 2025
Lumpy, but linear (reminded me of intestines) leafmine that followed the border of the leaf. There were spots of frass granules without a solid trail. The end of the mine (near the middle of the leaf) had a hole at the end, where I assume the larva exited to pupate.

Host: Lonicera
