Food Plant: various Compositae (daisy family) such as Senecio (Ragworts and Groundsel), Tussilago (Coltsfoot), Petasites (Butterburs), Aster, Eupatorium (Hemp Agrimony), Leucanthemum (OxEye Daisy), Tanacetum ( Tansy and Feverfew), Artemisia vulgaris (Mugwort)
Mine: Summer and Autumn
Pupa: External
Notes: The mine starts as a very narrow corridor, usually close to the tip of a leaf segment and following the leaf margin. The later section of the corridor approaches the main vein, where an elongated blotch is made with long broad finger like extensions that lay over the secondary veins. In the initial corridor the frass forms an almost continuous line, in the blotch it is distributed in large scattered lumps. In fresh mines the secondary feeding lines are clearly visible. Mine illustrated is on Eupatorium cannabinum (Hemp Agrimony)
