A very nice and big species, rediscovered in LX in 2010. This is so far we know the only observation this century for Belgium.
Native
Wingspan 17–24 mm. The forewings are dark ochreous yellow with sharp distinct white lines. The tips of the forewings are darker brownish.
The antennae are white, and there is a hairy extension at the base with the same color as the base of the forewings.
The larva constructs big black shiny cases of 19 mm. The mouth angle is 60°. The end of the case is strongly rolled in, which is the remnant of the youth case.
See also bladmineerders.be.
The larvae are fully grown at the end of June.
The adults are on the wing in July and August.
The larva feeds mainly on Genista tinctoria, also on Genista germanica, Genista sp. and on Chamaecytisus ruthenicus.
It inhabits xerotherm and dry areas.
