Butterfly Migration Update: May 22, 2008 They are few and far between, but monarchs have now reached latitude 45 north. Cool temperatures are slowing the migration northward. When the pattern breaks on Saturday south winds should bring warm air—and monarchs—northward. Let's see!

Butterfly Migration Update: May 15, 2008 The first monarch was spotted in Canada on May 8th this spring, the very same day as last year's first sighting. The big surge in numbers we have been predicting should occur any day. Let us know what you see! Meanwhile, explore the connections between milkweed and monarchs and enjoy a field trip to the milkweed patch in this week's slideshow. |

Butterfly Migration Update: March 27, 2008 It looked like fall migration along the Texas Gulf coast late last week there were so many monarchs! But the 'stop and start' nature of monarch migration is evident when you play this week's animated migration map. How closely do monarchs follow after milkweed becomes available in the spring? Dr. Brower explains why that's an important question. This week's photo is a monarch egg. Describe it! |

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. |
