Before and early 20th century, this species used to be very common around Dinant and Rochefort (NA) but it has not been seen for a very long time although easy to recognize. Rediscovered back in 2022 in NA.
Wingspan 12–13 mm. Male: head black, antenna slightly more than twice the lenght of the forewing. Female: head ferruginous, antenna slightly longer than forewing. Basal half of forewing pale, greenish brassy, just over half of the mid-wing a dark, slightly oblique fascia and beyond this intensively glossy reddish coppery colored.
Oval case built with soil and small plant particles, about 8 mm long.
The adults are on the wing from late June till early August.
The larva feeds most probably on Sedum album. Also known from egg-laying on Sedum rupestre and on Veronica spicata. Other plants mentioned are Succisa pratensis and Hypericum perforatum.
Xerotherm slopes on limestone where the foodplant grows.
