“…In Lithuania the possible summer host plant of M. rosae, Knautia arvensis (LINNAEUS, 1753) COULTER, 1823, is mostly inhabited by another closely related species, M. knautiae HOLMAN, 1972(RAKAUSKAS 1985, 2003a. The same holds for Belarus (BUGA et al 2012). Molecular phylogenetic studies of the M. rosae species complex showed the above species to be different in their EF1α sequences, but nearly identical in their COI sequences (TURČINAVIČIENĖ & RAKAUSKAS 2009).…”
