TABELL (2013: 481) meldet: "The larva feeds on leaves of Anthyllis cytisoides in the spring (in March in the province of Tarragona and the Baleares). The larval case (Fig. 7) is made of four pieces of the host plant, cut off from the vacated mines. The final case is 6 mm long, light reddish brown, bivalved, the oral opening at 30º. The larva pupates in the case fixed on the branch of a twig. The similarly constructed larval case of C. vestalella (Fig. 9) is darker and markedly larger (8 mm)." Und er vermerkt: "BALDIZZONE et al. (1981) depicted the larval case of C. rudella, based on Majorcan specimens reared on A. cytisoides by J. Klimesch. Nevertheless, this note is based on their misidentification of bred specimens, which actually belong to C. alacanta. Thus the figure represents the larval case of this new taxon too. The larval case of C. rudella is made of a floret of A. cytisoides (NEL, 1994)."
