Calosirus terminatus (Herbst, 1795)
The larvae tunnel in the petioles and stems, sometimes also in the root crown. Occasionally this seems to result in a gall. Pupation in the soil.
Robbins writes that sometimes the larva makes a full depth mine in a lower leaf, starting from the petiole; Hering denies this.
