Connections to the Course

Loss of Milkweed

  • Milkweed contains cardenolides, a steroid that is a cardiac arrester and toxic to predators
  • Predators throw up when they eat monarch butterflies and learn not to eat them
  • Viceroy population survives by mimicry
  • loss of milkweed due to herbicides
  • only plant that monarch caterpillars feed on
  • estimated 90% decline in population in last year
  • also effects mimicry
