For the first time recorded from Belgium in 2009. A second specimen was observed during August 2019. Hitherto only observations in WV.
An elliptical, tough cocoon woven with white silk and covered with fine particles of earth.
The species hibernates in the pupal stage, sometimes twice.
One generation a year: from mid July till September.
The caterpillar has been found in a great variety of vegetable matter: under seed-containing bird droppings on Abies grandis, in midge-galls on Salix caprea, on Juniperus, in spongy galls on Quercus, etc....
Has a preference for woodland with a lot of Taxus.
