A very nice and big species, rediscovered in LX in 2010. This is so far we know the only observation this century for Belgium.
The fore wings are dark ochreous yellow with sharp distinct white lines. In between small black stipples. The tips of the fore wings are darker brownish.
The antennae are totally white, there is a hairy extension at the base which has the same colour as the base of the fore wings.
Wingspan is 17–24 mm.
Larvae are making a big black shiny case of 19 mm. The mouth angle is 60°. The end of the case is strongly rolled in, it is the remnant of the youth case.

The case is to find in May and June. The larvae are fully grown the end of June.
They are on the wing in July and August.
It is a species from warm dry areas.
