Leaf mines
The linear mine is Agromyza aristata; the blotches (and the larval cases on the undersides) are Coleophora. There are two Coleophora spp. on elms; do you know how long these cases were (in mm)?

Thanks, Charley.
No, I can't hazard a guess on the length of the cases.
Feel free to move the pics wherever, or frass.
I may have seen adult Agromyzids but haven't yet had one identified.
