US-BUTTERFLY-MONARCH-SCIENCE-FILES
(FILES) -- A file photo taken on October 28, 2010 shows a Monarch butterfly on a flower in Los Angeles, California. The North American monarch butterfly (Danaus plexippus) is well known for its extraordinary migration, from the United States and southern Canada, thousands of miles southwards to the mountains of Michoacan in central Mexico, where it spends the winter. Monarchs are known to use a time-compensated sun compass to direct their flight. However, when weather conditions preclude this (overcast skies etc.), they remain flying in the expected southern direction. AFP PHOTO / GABRIEL BOUYS
