Agonopterix fruticosella (Walsingham, 1903)
Bupleurum rigidum, Spain; from Hering (1936b)
Relatively broad, brownish, full depth corridor of about 5 mm, without any frass. The larva emerges a short distance from the mine and causes window feeding, in which only the lower epidermis remains intact. Between the mine and the window lies a broad trace of frass, that keeps in place because of threads of silk. Mostly several mines in a leaf. Later the larva lives free under a spinning, even later in a folded leaf margin, fastened with silk.
Larvae collected in end June.
