A very rare species in the southern part of Belgium. Probably under-recorded due to the similarity with other species in this genus.
Rediscovered again through control of the genitals in NA, LX and LG during 2021 after a long period with no observations.
A medium-sized species. Wingspan 15–18 mm. Antennae white, not ringed. Head ochreous. The wings are strikingly elongated with the apex drawn forward. Forewing ground colour pale ivory, reticulation usually not visible or only very weakly. Bright spot at tornus present.
Yellowish, ivory skin with first abdominal segments weakly reddish-brown; Head black, thoracic plates dark brown with a reddish tinge.
9–12 mm, constructed from 4 to 6 crescent-like dry leaf particles.
Eggs are oviposited in the stems of several species of lower plants. The young larvae drop to the soil where they construct their first case and start feeding. The larval development takes two years. Hibernation as fully-grown larva or pre-pupa. Pupation during the last winter months or in early spring.
Adults are active during early morning sunshine but also in the afternoon and at dusk.
The adults fly in one generation a year from mid-May till June.
Different types of forests, mainly in cool habitats.
