A very local and rare species recorded only once in 1862. Probably extinct.
The forewings are ochreous-grey with a broad costal line. The other lines are very thin and closely covered with black dots.
Wingspan is 11–14 mm.
The antennae are ringed alternately brown white till the tip.
The caterpillar lives in an empty seed of the food plant.
See also bladmineerders.be.
Caterpillars are to be found from August till well in May.
The adults are on the wing in July and August.
Mostly on Artemisia campestris including subsp. maritima.
