Danaus erippus

Danaus erippus, the southern monarch, is a milkweed butterfly (subfamily Danainae) in the family Nymphalidae. It is one of the best known butterflies in South America. Its genome is nearly identical to D. plexippus, but the two are incompatible, and therefore considered separate species.
Danaus erippus is included with other Nymphalidae, the largest family of butterflies with about 6000 species distributed throughout most of the world. It has a reduced pair of forelegs, is brightly coloured, and is included with popular species such as the emperors, admirals, tortoiseshells, and fritillaries. Its wingspan reaches about 110 millimetres (4.3 in), with an easily recognizable orange and black pattern. Until 2007, this butterfly was treated as a subspecies of Danaus plexippus. These species are very similar, but D. erippus usually has an orange trailing edge of the forewings, while in D. plexippus it is black. The lineages of the two species are thought to have separated about 2 million years ago. The colour of the wings in males of the southern monarch is paler than in the females.

GBIF citizen-science records
It is estimated from how often the Southern Monarch is recorded against all the insects logged in Cordoba (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
