Phyllobrostis hartmanni Staudinger, 1867

on Daphne

mine

Oviposition in the leaf tissue. The mine begins a a fine corridor, often following the leaf margin. Next a large, somewhat inflated, full depth, blotch is made, extending from the leaf tip, that in the end may occupy the entire leaf. The mine contains much black frass that is glued to the upper epidermis, giving the mine a blackish appearance; only the sides remain free and are transparent. Pupation external; to leave the mine the larva makes a slit in the leaf margin, close to the leaf base.
