larva in mine

Charley, I had posted these two leaves in the species page, then I added this image of the caterpillar. Then I decided that you should notice them, so I sent all three to the Unidentified Mines page. I believe I read in an early blog post of yours that larvae in P. grandidentata don't reach maturity because of a callous that forms. Your opinion is welcomed.

Certainly looks like Ectoedemia argyropeza

I think I should have said it "usually" doesn't reach maturity on that host. If you can see the eggshell on the petiole, and a brown streak leading from it to the leaf blade (which I think I can see in your photos), that would confirm the ID.

Yes,

those signs are there. I have collected leaves from both populus species (separated in 2 jars), and several have larvae. We'll see what comes up in the spring.
