First time observed in Belgium in 2016 in LX. Hitherto a very rare and local species in the southern part of our country.
Native
Wingspan 14–17 mm. Eyes red. Head and thorax unicolorous brown, palp pale ochreous. Forewing variable brownish or dark greyish, slightly pale bluish tinged, more or less sprinkled with darker scales, stigmata dark brown, rather indistinct, discal stigma 2 most prominent (Gregersen & Karsholt 2022), a light postmedian fascia indicated, three to five indistinct spots near termen. Hindwings greyish brown.
Can be externally very similar to Anacampsis scintillella which is usually smaller, but not always separable without dissection of the genitalia.
Abdomen reddish brown to blackish brown, head blackish brown to black, prothoracic plate black, large and bisected by a narrow structure, anal plate brown to blackish, pinacula blackish brown with strong setae.
The pupa is reddish brown with a short cremaster not clearly differentiated. Its sides are rather straight to slightly convex to the end.
The larvae live in a transversely rolled leaf on the host plant. Pupation takes place on the ground.
Adults are attracted to light.
The adults have been seen from early June towards late September.
The monophagous larva lives on different species of Quercus.
It occurs in warmer oak forests or oaks standing in xerothermic places.
