Every fall, the monarch butterfly begins a journey that will take it some 1,800 miles (2,900 km) and through four generations before they return. The first generation begins their migration by flying to wintering locations along the California coast. There they cluster in eucalyptus groves along the coast and mate in late January, then they leave for their spring migration by March. They lay their eggs inland on milkweed plants in the Sierra Nevada foothills and then they die. The second generation hatches and flies across the mountains into Oregon, Nevada or Arizona. The third and fourth monarch butterfly generations fan out even further and then they return to California, to the place where their great great grandparents started.
