A widespread but rare species in Belgium.
Native
Wingspan 18–23 mm. Males are distinct in having a large white torno-apical blotch as well as the large white medio-dorsal blotch and a grey hindwing.
Females require genital dissection to distinguish from Epiblema cirsiana and Epiblema sticticana.
The larva lives in the roots and the stem on the host plant where it hibernates in the larval habitation. Pupation takes place in the upper part of the larval mine.
During the day, the adults rest on the larval foodplant, where they resemble a bird-dropping. They are active at dusk and come to light.
The adults have been observed from April till September.
The larva lives on Carduus nutans, Cirsium vulgare, Cirsium palustre and Carlina.
It inhabits rough grounds, open woodland, roadside verges, wasteland and meadows.
