Mentioned for the first time in Belgium in 2018 from 7 specimens identified through genital examination by J.-L. Renneson in an old collection from 1951 (now deposited in RBINS), Torgny (LX), leg. M. Fontaine.
Perhaps other specimens of this species are hidden in series of Zygaena purpuralis because the external morphology of both species is much alike.
Native
Wingspan 33–37 mm. The imago is not distinguishable from Zygaena purpuralis in the field, only by genital dissection.
The adults are active during the day. The adults like to feed nectar on Knautia arvensis, Dianthus carthusianorum and Echium vulgare.
The adults are on the wing in June and July.
The larva feeds on Pimpinella saxifraga.
Calcareous grasslands, nutrient-poor meadows or open pine forests in limestone areas.
