Rubus idaeus, Cadzand

mine

First a long corridor, its initial part often along the leaf margin or a thick vein. Rather suddenly the corridor widens into a broad blotch. The corridor contains much, amorphous frass that sometimes seems to fill the entire corridor (lower picture). In the blotch the frass is in black strings and coarse lumps. (In rainy weather they liquify and loose their shape). Pupation outside the mine.
