Origin and distribution
• Butterfly very ubiquitous, Europe, Africa, Sri Lanka, India, China, Sulawesi.
• Danaus chrysippus is a butterfly that can live in many biotope, from desert, to the height mountains, up to more than 1500 m), passing through tropical rainforest areas (in open habitats).
• Danaus chrysippus, like most butterflies lives with his wings closed in general.
• During its migrations, when it arises near the ground or on plant material, it opens its wings and turns them toward the sun. Thus they are fully exposed to sunlight.
• Danaus chrysippus is protected from attacks by the association of its colors, the speed of its flight (slow, giving every opportunity to its predators to recognize him) and the presence in its body of emetic alkaloids. Predators "understand" that the butterfly should not be ingested, they pass their way.
• Another defense is to mimic a state of death and issue a smelly secretion. Perceiving these odors, predators spend their way. It seems then, for the novice, as Danaus chrysippus is capable of a "miraculous" resurrection after a predator attack.
• It is a medium sized butterfly (seven to eight centimeters). Its body is rather dark, ornate white punctuation.
• The wings are colored orange, more or less dark. The apex of the forewing is brown to black, ornamented with large white dots, sometimes coalescing into a white band crossed by the ribs. The posterior edge of the wings is also dark and provided with semi-circular white dots. The hind wings are ornamented by three black dots in the center.
• The hind wings of the male carry on rib number 2 a black punctuation bordered white. It is a gland emitting a pheromone attractive to females.
• Males specimen are smaller, but more brightly colored than females.
• Given its defensive behavior, evolution has led to other species of butterflies that look very similar to Danaus chrysippus: adopting a same dress, the mimes are able to escape predators, who confuse them withDanaus chrysippus.
• Except for pollinating activities, the butterfly does not have much economic impact.
