host plants

Caryophyllaceae, oligophagous

In the literature, saponariae is also recorded from, among other species, Arenaria pungens; Minuartia hybrida; Moehringia muscosa; Silene viscaria. In the light of the revision by Vánky & Lutz (2007a) these identifications should be regarded as “sensu lato”.
