Cameraria? A species I've seen before?

Moved
Moved from Coptotriche badiiella.

I've made a "badiiella or purinosella" page to store these until I can be sure how to distinguish mines of these species.

Moved
Moved from Unidentified Leaf Mines.

This isn't a species I've seen before, but everything seems to fit. Note the lack of frass and the trumpet-shaped beginning (egg deposited on a lateral vein), both indicating Coptotriche rather than Cameraria. This species is almost exclusively found on Q. alba.

 
I should add...
There is a small chance that this is C. purinosella, but I still think C. badiiella is most likely. I should be able to tell definitively from the pupa even if no adult emerges.

 
It seems to be putting frass
It seems to be putting frass out a hole in the mine--is that something Coptotriche does?

 
Yes
Most tischeriids do, although there are three common oak miners that don't.
