Danaus, commonly called tigers, milkweeds, monarchs, wanderers, and queens, is a genus of butterflies in the tiger butterfly tribe. They are found worldwide, including North America, South America, Africa, Asia, Indonesia and Australia. For other tigers see the genus, Parantica.
Following the review of Smith et al. (2005), 12 species are provisionally accepted based on morphological, mtDNA 12S rRNA and subunit I, and nuclear DNA 18S rRNA and EF1 subunit α sequence data:
This genus was formerly split into the subgenera Danaus, Salatura, and Anosia, but this arrangement has been abolished. While the first (the 2–3 monarch butterflies) and Salatura (species ismare, genutia, affinis, and melanippus) do indeed seem to be clades, the relationship of these to the other species, especially the puzzling D. dorippus, is not clear.
Hybridization producing fertile offspring is known to occur between some species, confounding mtDNA data; this seems to be especially true in the case of D. dorippus (Smith et al. 2005). In addition, male-killing Spiroplasma infection has been shown in D. chrysippus and probably also occurs in other species (Jiggins et al. 2000); the consequences for speciation and evolution are probably similar to those observed in infection with male-killing strains of the better-researched Wolbachia bacteria.
