Adults range from Mexico through Panama.[1]G. oto visits common flowers like lantana, but prefers to lay its eggs on plants of the tropical nightshade genus Cestrum.[1] The red and purple striped caterpillars feed on these toxic plants and store the alkaloids in their tissues, making them distasteful to predators such as birds.citation needed] They retain their toxicity in adulthood.citation needed] The same alkaloids that make them poisonous also are converted into pheromones by the males, which use them to attract females.citation needed] G. oto adults also exhibit a number of interesting behaviors, such as long migrations and lekking among males. en.wikipedia.org/wiki/Greta_oto
