This is a rare moth in Belgium and there were also a lot of misidentifications in the past.
The forewings are brownish grey with fine but distinct yellow lines. The antennae are alternately ringed from 2/5 till 3/5 of their length.
The wingspan is 13–17 mm.
The tubular case measures 8–10 mm. This case is trivalved and made of silk. The mouth angle is 20°.

The larva lives in a tubular tube and feeds on the fruits, both green and ripe black, often close to the ground and hidden in the vegetation. The caterpillar feeds on from August to September and, after hibernation, until May.
They adults are on the wing from the end of June till the beginning of August.
