First observation at the beginning of the 19th century (NA). The second observation was only in 2018 (AN),and third observation in 2019 (LX). Needless to say, this is an extremely rare and local species in Belgium.
Native
Very little is known about the pre-imaginal stages. The eggs are presumably laid on the bark of Salix trees, but neither the larva nor the pupa are described.
One generation a year from June till August.
Several species of Salix.
