A fairly common species in Belgium.
Whitish, semi-transparent skin; head brown; thoracic plates lighter brown.
10–12 mm, constructed from 4 to 5 crescent-like dry leaf parts, gradually in larger format.
The eggs are deposited in the stems of lower plants like Glechoma hederacea or Lamium galeobdolon, though these plants do not serve as a larval food plant. After hatching, the small caterpillars drop to the soil where they make their first case.
The adult moths are active in the early morning, the afternoon and at dusk. The males can be observed swarming from an hour before sunrise until just after the sun appears. They come occasionally to light.
The adults fly in one generation a year from early April till early June.
Bright deciduous forests, with a preference for mixed forests with Quercus and Fagus in xerothermic habitats.
