Phyllobrostis daphneella Staudinger, 1859
Oviposition probably within, rather than upon, the leaf. The larva makes a full depth gallery. The frass is glued to the upper epidermis, giving the mine a blackish appearance. Part of the frass is also ejected through a slit in the lower epidermis. Pupation outside the mine. To leave the mine the larva makes a cut in the leaf margin, close to the leaf base. Pupa in a cocoon in a leaf fold.
Thymelaeaceae, narrowly monophagous
Two generations; adults in April-May and August (Mey, 2006a).
distribution within Europe
Southern France, Iberian Peninsula, Corsica, Sardinia, Italy; also NW Africa (Mey, 2006a).
Staudinger (1867a) and Hering (1957a) write that the older larvae live free among spun leaves. This is not confirmed by Mey (2006a), even though Staudinger is very explicit at this point.
