Las primeras mariposas monarcas han llegado! The first monarchs have
arrived! After crossing half a continent, the monarchs must strike
a finish line about 70 miles wide. What's so special about this place?
Monarchs travel to a very small region in Mexico from across eastern
North America. Within
the region, only 12 places have the habitat the butterflies
need to survive. What's so special about this place for monarchs?
Also,
Estela Romero tells us about Dia de los Muertos, and the local belief
that monarchs are the returning souls of ancestors |

Eight days after a cold front pushed spectacular numbers
of monarchs across west Texas, monarchs cruised across the skies
of northern Mexico, 300 miles to the south. But this time, people
saw "miles y miles de mariposas monarcas" and said that
a "frente frio" was responsible. The migration is in northern
Mexico at last! The route the monarchs travel through Mexico presents
a mystery: why don't the butterflies travel straight south? Explore
some maps and read Dr. Bill Calvert's thoughts on the subject. |

A strong cold front moved across Texas, the wind shifted
to the north and "hundreds upon thousands of Monarch butterflies
were riding the front, heading south." The sky was filled with
Monarchs drifting on the strong tailwind. How high do monarchs
fly? Puzzle this out with pictures from the sky. And this
week's news from the Monarch's winter home in Mexico--they're arriving! |

This fall’s extraordinary migration has added a remarkable
chapter. The largest gathering of the season is now resting and refueling
in Arkansas. In New Orleans, hundreds were migrating along the longest
bridge in the world rather than travel across the open water. Such
careful water-avoiding behavior makes one wonder: how did monarchs
reported this week in the Bahamas and England get there? "Por
fin en México!!!" came the word as this report was about
to go out the door. Monarchs are crossing the border at the rate of
100 per hour. |

It's a unique year. Monarchs are unusually abundant in the
East and scarce in the Midwest. This fall’s migration map is
revealing a pattern we’ve never seen before. It sheds light
on a migration mystery: Which way do monarchs from the East Coast
travel to Mexico? |

A spectacular migration is moving down the Atlantic Coast
right now from Maine to Virginia. On Monday, over 13,000 monarchs
rested on the Massachusetts Coast. On Wednesday, a clear wave traveled
over New York City and delighted those who saw butterflies fill the
sky. This map shows three great places to watch monarch migration
on the Atlantic Coast. A combination of wind, geography, and monarch
behavior explain it. Can you see why? |

Summer is over! People noted the "stop and go"
nature of monarch migration during the dramatic change in weather
this week. Monarch butterflies are in a race against time during fall
migration. They can't fly if it's below 55F. When and where can a
monarch fly today? |

As monarchs pass overhead on their way to Mexico, you may
wonder, How fast do monarchs migrate? Where will the butterflies I
see right now be in a few hours, days, or weeks? Nobody can travel
with a butterfly, but tagged monarch butterflies tell amazing tales.
Today's true stories show how much a few tiny butterflies can teach
us about migration. |

September 8, 2006
Which way to Mexico? Monarch navigation has mystified researchers
for years. How do these insects find their winter home deep in the
Transvolcanic Mountains? Learn about the current theories. Imagine
you took wing to fly along with them -- what would your journey look
like? The monarchs are marching down the map towards their final destination.
Reports coming in this week as far south as 40N. Take a free minute
and set your eyes on the skies! |

The migration to Mexico is underway! The word came first
from Ontario this year, and the date was only August 3rd. Do monarchs
migrate earlier than the science books say? Before the Internet, collecting
such an observation would have been hard. Now, "citizen scientists"
are contributing important information about monarch migration. We
hope you're ready to help! |
