same mine, detail
Upper surface. The mine begins as a short, compact brown spiral, followed by a secondary blotch, often at the leaf margin. Often spiral and blotch are separated by a recognisable corridor segment. Secondary feeding lines conspicuous (in fresh mines). Pupation outside the mine; sometimes pupation occurs earlier but then the exit slit already has been made, and the spiracula do not penetrate the plant epidermis.
Mentha aquatica, arvensis, longifolia, x piperita, x rotundifolia.
