Moved
Moved from Unidentified Leaf Shelters.

Just so we're clear... these Phyllonorycter and Coptotriche photos all show leaf mines, not shelters made by tying/folding leaves externally.

If this is a leaf mine, then
If this is a leaf mine, then does that mean the whiteish surface on the underside is actually part of the leaf?

Yes
The larva starts by making a mine that is only visible on the lower surface, then deepens it and spins silk inside, causing the leaf to buckle and give the larva more room (this is called an "underside tentiform mine").

In contrast, this is what I call a "pseudomine"

where the larva has spun a sheet of silk on the surface and is now "window-feeding" beneath it, producing a similar effect.
