A very rare species in Belgium, seldom recorded.
Native
Wingspan 11–14 mm. Forewings black, with a faint blue or violet sheen with a prominent pale transverse band. A small, white costal spot on the underside of the forewings. Hind wings as wide as forewings, brownish gray.
A. cinctella can have a straight or slightly inwardly curved fascia. This feature is therefore unsuitable on its own as an identification feature and genital control is necessary.
The larva lives between spun leaves on the host plant.
The moths are active from late afternoon onwards and later come to light.
The adults fly from mid-June towards late July.
The larva lives on Lotus corniculatus, Trifolium repens and probably also Trifolium pratense and Genista.
It inhabits rough, dry ground, grasslands, open woodland, often on calcareous soils.
