In Greek mythology, Plexippus participated in the hunt for the Calydonian Boar. He was angry that the prize of the boar's hide had been given to a woman by Meleager, who then killed him in the ensuing argument.
The Biogeography of the Monarch Butterfly (Dannaus plexippus)
Based on genetic and phenotypic evidence, the theory that D. plexippus is a descendant of a divergent genera which migrated to the Americas 250,000 years ago suffers.
Recently, D. plexippus was at the center of a controversy concerning pollen from bioengineered corn.
Danaus plexippus ranges from North and South America and the Caribbean to Australia, New Zealand, the oceanic islands of the Pacific, Mauritius, the Canary Islands of the Atlantic, and, most recently, Western Europe.
plexippus is a predominantly open country, frost intolerant species whose range of breeding habitats is greatly dependent upon the presence of asclepiad flora (milkweeds).
plexippus is fairly simple and less dependent on chemical pheromones in comparison with other species in its genus.
