Ceutorhynchus pallidactylus (Marsham, 1802)

cabbage stem weevil

mine

The larva essentially is a borer in the petiole or the stem; from the point of oviposition it eats itself the way down. But oviposition in the midrib may occur as well (even in the lamina) and under such circumstances the larva may make short, frass-free corridors from the midrib into the leaf.
