Nemorimyza posticata (Pupa) 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&#039;m concerned about the damaged strip. I don&#039;t know what caused it, but am hoping it can still develop properly.<br /> <br /> Video of larva in mine: <section class="video"><iframe width="448" height="282" src="https://www.youtube-nocookie.com/embed/uTL3NcbcF6s?hd=1&autoplay=0&rel=0" frameborder="0" allowfullscreen></iframe></section><br /> <br /> Host: Solidago<br /> <figure class="photo"><a href="https://www.jungledragon.com/image/171050/nemorimyza_posticata.html" title="Nemorimyza posticata"><img src="https://s3.amazonaws.com/media.jungledragon.com/images/3232/171050_thumb.jpg?AWSAccessKeyId=05GMT0V3GWVNE7GGM1R2&Expires=1759968010&Signature=D7vh4Swb5eIc5Ci43TGoWTiCkDg%3D" width="120" height="152" alt="Nemorimyza posticata Blotch/trumpet-shaped with frass smeared throughout.

      Thanks! It picked the worst spot, but at least it's safe. That lighter/damaged part darkened, so I'm hoping it is healthy. Posted 8 days ago
