Cirsium arvense: egg, and surface sculpture
Large, very transparant blotch, with primary and secundary feeding lines. In the centre a concentration of black frass. Mines can coalesce, and then contain several larvae. At the start of the mine, at the leaf underside, a white egg shell. Howevver, the larva can leave its mine and restart elsewehere, therefore mines without an egg shell may occur as well.
Asteraceae, narrowly oligophagous
Larvae observed from June to August.
