FINAL Monarch Butterfly Migration Update: November 11, 2005
Sanctuary trees are filling with butterflies as millions of monarchs
pour in from the north. Why do they migrate to this part of Mexico?
What’s so special about it anyway? Explore maps and photos
and form your own theories. When Journey North begins again next
February, we’ll take a close look at the monarch’s winter
habitat and how the butterflies are adapted to survive there. To
prepare, collect weather data from the region once every month.

Butterfly Migration Update: November 4, 2005
Las primeras mariposas monarcas han llegado! The first monarchs
have arrived! After crossing half a continent, the monarchs must
strike a finish line about 60 miles wide. Another surprise this
week: monarchs were reported from two separate islands in the Bahamas!
Butterfly Migration Update: October 28, 2005
Still no monarchs, says Estela Romero, who's watching and waiting
from her home near the sanctuaries in Mexico. Like clockwork, they've
arrived at the same time every fall since ancient times. They represented
"for our ancestors in pre-Hispanic times, the souls of the
dead coming back to earth to be for short time together with us,"
says Estela. Meanwhile, monarchs continue to stream down from the
north. Late migration is a risky business. Take a look at temperature
maps. When and where is it too cold or dark for a butterfly to fly?
Butterfly Migration Update October 21, 2005
While we wait for the monarchs to reach their winter home in Mexico
we wonder, will they find it this year? Here is a huge NASA image
of planet Earth floating in space. Can you find the monarch sanctuaries?
This week, learn the geography monarchs know by instinct.

Butterfly Migration Update October 14, 2005
migration is at its peak in Texas! Last week monarchs were "streaming
south" and "sailing on northeast breezes." There
were "hundreds, if not thousands" and they were "anywhere,
anytime we looked up!" High-flying butterflies were floating
past windows in downtown Dallas and the town took notice. How high
were they flying?
Butterfly Migration Update October 7, 2005
"Spectacular sightings in Texas this week, as monarchs move
closer and closer to the Mexican border in massive numbers. "The
sound of the fluttering wings was louder than you might think a
butterfly flap to be!" said a woman who saw "zillions"
in San Angelo. Do monarchs cross Texas on two monarch flyways? Watch
today's migration animation and see what you think.
Butterfly Migration Update September 30, 2005
"Here they come!" one person called to the next as the monarchs
moved with the wind across Oklahoma and into Texas this week. "Finally,
monarchs everywhere on the Virginia shore," came the word as
a huge wave of monarchs swept down the mid-Atlantic Coast. How fast
can monarchs migrate? As monarchs pass over your head on their way
to Mexico you may wonder how long their trip will take. Where will
the butterflies be in a few hours, days, or weeks? The recovery of
one tagged monarch reveals some clues.
Butterfly Migration Update September 23, 2005
The monarch migration picked up in the East last week.
Butterflies passed at 296/hour in Cape May, NJ and the season's
first wave reached Dr. Brower's mountaintop garden in Virginia.
How long can a butterfly fly before running out of fuel? Take a
look today at the energy costs of flight. A butterfly garden can
be an important place for a monarch to refuel. Find out how you
can help habitat on the monarch migration trail.
Butterfly Migration Update September 16, 2005
"Amazing!" "Wow!" "What an incredible
sight!" came the word from the Midwest on Wednesday the 14th
as this fall's first classic cold front swept across the region.
How many monarchs per hour did each observer see? Learn about "migration
rate math" and predict who will see the record flight in Fall
Butterfly Migration Update September 9, 2005
Hurricanes are among the hazards monarchs may face as
they migrate. This week: a tagged monarch tells an uplifting story
of survival. If Hurricane Katrina carried this monarch 165 miles
in the wrong direction, could the wind carry a monarch across the
Atlantic Ocean? Compare a monarch’s weight to a scrap of paper
and consider the role wind plays in a butterfly’s daily life.
Butterfly Migration Update September 2, 2005
Migrating monarchs rest at overnight roosts at the end
of the day. What can we learn about their migration patterns from
their resting patterns? Also this week: Find the
monarch's winter home in Mexico and your own home on a satellite
map. Then zoom-out and fly like a butterfly all the way to Mexico!
