This species is only known from one old record in 1925 in HA. At present, it is considered extinct in Belgium.
The forewings of this moth are ochreous to brown with lighter longitudinal stripes. Wingspan is 14–17 mm. The antennae are thickened at the base, they are alternately ringed but obscure.
This species constructs a yellow-brown lobe case of 10–12 mm in length when reaching its full development. The mouth angle is circa 80°.

The larvae are full-grown in May. In literature it is also mentioned that the caterpillar can stray around quite a bit before pupating and therefore can end up on many other plants, making identification more difficult. In this context is also put forward that the association with Veronica as hostplant genus perhaps needs further investigation.
The adult moths are on the wing in June and July.
As host plants for the larvae this species are mentioned Teucrium chamaedrys and Veronica-species.
