In general a rare to very rare species in Flanders (mainly known from the Kempen area) and fairly common in Wallonia.
Like other Lithophane species it is known for its cannibalistic behaviour.
It pupates in a sturdy cocoon underground.
Hibernates as an adult under loose bark or in another sheltered situation.
The adults are active from dusk onwards and later come to light and sugar.
The adults fly mainly in September and October, sometimes till December, and after hibernation again in March till the end of April, occasionally later.
The larva lives on various deciduous trees, but mainly on Quercus.
