A widespread but local species in Belgium, it has increased in the north of the country since 2004. Locally common in some parts of the south of the country.
Larvae mainly live on Lonicera, mostly on humid locations and in the shade or semishade. Before hibernation the brownish larvae create a typical feeding pattern on the Lonicera leaf where it starts eating from the top but leaves the midrib of the leaf untouched. For hibernation the larva uses a leaf to create a hibernaculum and after hibernation the final instars of the larva get their typical green color with reddish spines.
The adults fly in June and July. Sometimes there is a small second generation from end of August to September.
The larva lives on Lonicera or Symphoricarpos.
