Butterfly Migration Update: June 11, 2009 Cloudy, cold, windy and rainy...that's the weather report from much of the north where monarchs have yet to appear widely. This is not butterfly weather! Also this week: Volunteers are needed for the Monarch Larva Monitoring Project. You can help scientists study monarch populations by establishing your own study site. Why the red flags in my study site? |

Butterfly Migration Update: June 4, 2009 Monarchs have now entered Nova Scotia! A sighting there puts the eastern edge of the migration nearly 3,000 miles from its origin in Mexico. Monarchs have also been sighted in the last two northeastern states. Can you name them? Also this week, learn how you can help scientists study the monarch parasite "OE." Look at the two species' life cycles and see how closely they are interconnected. |

Butterfly Migration Update: May 28, 2009 Canadians welcomed the monarchs' return this week as large numbers of butterflies reached the final nation of their tri-national migration. People from five new states and provinces reported monarchs this week. Use these geographic clues to find out which ones! Go on a milkweed hunt in today's slideshow. Milkweed can hide right in front of your eyes. Can you spot the milkweed in these pictures? |

Butterfly Migration Update: April 16, 2009 Dr. Brower says frost damage to milkweed is a hazard monarchs face in the spring. What are other risks of moving north too quickly? The monarchs have now moved into 4 new states and reached latitude 47N. Sightings from the East Coast raise interesting questions: Did those monarchs came up from Mexico or from the coast? Also, can you name another long-distant migrant that eats nectar and is traveling now? Photo: Bud Hensley |

Monarch
Butterfly Migration Update: March 26, 2009 The first monarchs have already been sighted in Arkansas and Oklahoma—and the 19 fresh eggs found yesterday in Jackson, Mississippi are evidence that monarchs have even arrived there! What does spring migration look like, and can you solve the migration mystery in California? As the final butteflies leave the overwintering sites in Mexico, the town of Angangueo honors monarchs and the first day of spring. Photo: Estela Romero |

Butterfly Migration Update: March 19, 2009 The monarchs are pouring out of Mexico now and arriving in Texas where severe drought conditions greet them. How could this affect the butterflies? Predict where the migration will travel next. (You might be surprised!) Why do the monarchs travel when and where they do? Find out why collecting this information is important.

Monarch
Butterfly Migration Update: March 5, 2009 Spring migration is about to begin! "Girls and boys: Monarchs will indeed leave our forests in only a few days," wrote Estela Romero from Angangueo. Millions of monarchs are about to take to the sky and begin their journey north. They will migrate across the continent in response to Earth's seasonal cycles. What triggers their departure? Look at these line graphs for clues and make predictions. Get ready to explore the many time-sensitive connections between monarchs, climate and the seasons. |

Butterfly Migration Update: February 19, 2009 "The sounds of monarch wings in flight was overwhelming," said Susan Myers after visiting the butterfly sanctuary on Monday. The final weeks of the monarch's winter season are here and temperatures are rising. Why did the monarchs migrate to a place that is so cold? Today, find out how cold temperatures help monarchs survive the winter, and the challenges cold temperatures present. |

Butterfly Migration Update: February 12, 2009 Every 98 minutes the satellite zips around the world. It's 438 miles high and it's traveling 17,000 miles per hour. On board is one of the world's most powerful cameras. Any day, between now and mid-March, the camera will take a snapshot of Mexico's monarch butterfly Reserve. Find out how this satellite and high-powered camera can help scientists protect the monarch's forest for people and monarchs. Who made this possible? Students! Image: GEOEye |

Butterfly Migration Update: February 5, 2009 Welcome to Journey North's spring's migration season! It's been three months since the first monarchs reached their winter home in Mexico after their long, fall migration. How many monarchs are in Mexico this winter? Find out why scientists count butterfly trees instead of butterflies to answer that important conservation question. Also, why are the trees in this picture orange?

Welcome to Journey North's spring monarch migration season! Winter
>> We
begin each year while the monarchs are still at the overwintering sites,
deep in central Mexico. The monarch’s story of survival during the
winter months in Mexico is as spectacular as their incredible migration.
During the first weeks, we’ll look at the monarch’s winter
habitat and their adaptations for survival. |
