Nemorimyza posticata Blotch/trumpet-shaped with frass smeared throughout. When backlit, you could see the larva in the mine. The pupa exited the mine on 8/20/25. It pupated in the cover of the vial. I'm concerned about the damaged strip. I don't know what caused it, but am hoping it can still develop properly.<br />
