The nearest known ally of this species is the European C. Brongniardellum, not C. calicella St., as I suggested before I knew Brongniardellum. Albanotella makes a large, somewhat tentiform mine, on the under surface of oak leaves (Q. obtusiloba and Q. alba); the mine is at first long, winding and Nepticuli-form, ending in the large tentiform blotch. The lanva, before leaving the mine, becomes pinkish red. In the breeding cage it pupates in a cocoonet which it spins on the surface of the leaves. I have never met with the pupa elsewhere, nor have I ever, although I have seen hundreds of the mines, found one on the upper surface of the leaf.
