Spotted something wrong?

Fun facts

  • The caterpillars feed exclusively on milkweed (Asclepias), which makes them toxic to many predators.
  • The autumn migratory generation can live 6 to 9 months, far longer than the summer generations.
  • It overwinters in vast colonies in the oyamel forests of Mexico and in California.
  • comportamientoIts migration spans several generations: no single butterfly completes the round trip, and yet the generations that follow return to the very same place.
