Livilla cognata (Löw, 1881)

Feeds on

Oligophagous on Chamaecytisus spp. and probably also Cytisus and Genista spp. It was recorded from Chamaecytisus ratisbonensis (Schaeff.) Rothm. in Austria ( Löw 1888) and Czechia ( Lauterer 1965; I. Malenovský, personnal observation), on Genista germanica in Czechia ( Lauterer 1965), on Ch. hirsutus (L.) Link and Cytisus nigricans L. in Italy ( Conci et al. 1993) and on Ch. heuffelii (Wierzb.) Rothm. in Serbia ( Jerinić-Prodanović 2010). In Bulgaria, we collected adults and immatures on Chamaecytisus elongatus (Waldst. & Kit.) Link. , which is a newly-confirmed host species. We also repeatedly collected adults on Ch. austriacus subsp. stefanofii (Stoj.) Kuzmanov , which is another probable host.
