Mexico: the ideal residence of monarch butterfly (Danaus plexippus)

The annual movement to the south and the precise response to Mexico's Angangueo forest to find the danaus plexippus 'winter shelter still continues to attract scientists' inquiry. During this year's immigration season, a natural environment specialist sought to fly this particularly precise migration path.

Natural environmentalist Francisco Gutierrez is trying to draw people's attention to the fragile existence of the Mexican butterfly meadow. He flew along this butterfly's 4,500-kilometer migration path and ended the flight yesterday.

Gutierrez's ultra-light Papalotzin landed on Angangueo in the state of Michoacan, Central Mexico. This is one of the dense forests of the western Mexican capital, which is also an ideal refuge for the annual migratory monarchs from Canada.

The World Wildlife Fund, the state government of Michoacan and the Mexican mobile phone company Telcel sponsored Gutierrez's flight.

Every year, from the United States and Canada, millions of completely new generation monarchs fly south and respond accurately to the wintering forest in Mexico. Scientists still do not understand this celestial process thoroughly.
