Species and habitat races in the chrysomelid Galerucella nymphaeae species complex in northern Europe
Abstract The taxonomically controversial Galerucella nymphaeae species complex (Coleoptera, Chrysomelidae) contains at least two distinct species in northern Europe, G. nymphaeae (L.) consuming Nuphar luteum , and G. sagittariae (Gyll.), living mainly on Comarum palustre in southern Finland and on R...
