very rare and local species in Belgium, hitherto known from only a few
observations in one locality in the province of Antwerpen in the
Kempen. The first record for our country was on 09 July 2004. Recently
also discovered in other provinces, seems to be expanding its range.
larva lives on a variety of marsh plants, like Cicuta virosa, Menyanthes trifoliata, Lysimachia, Solanum dulcamara, Nephrodium thelypteris, Convolvulus arvensis, Plantago, Arctium etc... Hibernates as a pupa in an underground cocoon.
adults fly in one, sometimes two generations a year; from mid
May till end of August. They come sparsely to light, but are also
reported from sugaring.
