Many lower leaves on this tree were similarly marked. I didn't find the creatures responsible.

Moved
Moved from Stigmella corylifoliella.
Erik J. van Nieukerken says that western hazelnut mines are made by a different species. Since its exact identity is as yet unpublished information, we'll leave this at genus level for now.

Moved
Moved from ID Request. Nepticulids mature and leave their mines very quickly, so it's unusual to find the larvae still in the mines--I'm not sure that I've ever actually seen them.

Stigmella corylifoliella is an atypically generalist species, feeding in plants of at least four different families (see guide page).

Host plant...
..might be Alder (Alnus), possibly Red Alder (A. rubra). or White Alder (A. rhombifolia).

An even better fit...
...in the same plant family (Birch family - Betulaceae) would be California Hazelnut (Corylus cornuta var. californica).

Hazelnut was my first thought...
...but I'm unfamiliar with California species, and it turned out that a nepticulid mine on just about anything in the birch family (except musclewood and hophornbeam) would be the same moth anyway.
