Ceutorhynchus rapae Gyllenhal, 1837

mine

The larva essentially is a borer in petioles and stem. Several larvae live together in a cavity; at that point the stem is swollen. From that swelling now and then a larva may stray into a leaf. The stem above the gall usually dies off, and is replaced by a number of new side branches.
