As many as 200 million Monarch butterflies may migrate to Mexico this year – 10 times more than in 2004, when unfavorable weather, pollution and deforestation caused a drastic decline in the population.

The butterflies began reaching Mexico at the end of October and usually continue to stream south until early December. The spectacle of millions of orange and black butterflies carpeting fir trees attracts 200,000 visitors a year. Authorities plan to open four major sanctuaries to tourists on Nov. 19.
