As also other ornamental plants in the neighbour pots are heavily mined (Raphanus sativus var. sativus, Tropaeolum majus - see below, Antirrhinum majus), the polyphagous Chromatomyia horticola is under suspicion.
Help is appreciated - thanks! Sundew

P.S. Location is southwestern Germany, 20 km west of Stuttgart.
