A new species for Belgium in 2020 in WV. Hitherto only a few observations are known.
The social living larvae feed on the needles of Ulex europaeus in which they spin a dense, conspicuous web structure. The adults come to light.
The adults are on the wing from mid June towards mid August.
Heathland and dunes, mostly coastal.
