A pupal case that was constructed from Ostrya virginiana. The larva cuts a matching piece from the upper and lower surface of the leaf and binds these together to create the case. This leaves a single hole at the end of the mine.
This species produces tiny blotch mines like this one on an Ostrya virginiana leaf. Note the darker frass on the inside, and the feeding larva near the top of the mine.
The mine starts out being narrow, but rapidly expands into a blotch mine like this one on Ostrya virginiana. Note the elliptical hole where the larva excised leaf pieces to construct its pupal case.
