Glaucolepis headleyella (Stainton, 1854)
Prunella vulgaris, Germany, Eifel, Alendorf; leg Diersystematiek VU
Egg at the upper side of the leaf. The mine is an extremely long corridor, often following the midrib or the leaf margin, with frass in a narrow central line, widening in the end into an irregular elongate blotch. Corridor sides somewhat irregularly scalloped out, especially towards the end. The larva may move, all the while mining, to another, even a third, leaf by way of the petioles and stem. Therefore one leaf may have only a narrow corridor, another a blotch. Pupation external. Mines mainly in the lowest leaves, difficult to find, but it helps that infected leaves and leaves nearby often turn violet.
