Spring 2011 is History
Look at this spring's migration map. Like pieces in a puzzle, each individual observation helps us see the whole. Thank you for contributing your observations. As we say goodbye to spring migration 2011, we leave a legacy for science. This year's migration is now part of a permanent archive. Take a look!
Try This! Summer Monarch Observations
Your First Monarch
If you haven't seen your first monarch of the season yet, please report it when you do!
How Many Monarchs per Day?
Keep a tally of the number of monarchs you see each day over the coming months. Report your count under "Monarch Other Observations." Expect to see higher numbers as new generations appear. In southern latitudes, watch for monarchs to reappear sometime in August. Please report the date you see your first.

Lazy-like Summer Flight
Watch how a monarch flies during the breeding season, as it searches for nectar, milkweed, or a mate—or avoids a potential predator. Flight behavior is "non-directional" at this time of year, with unexpected ups, downs, twist and turns. "They fly like they're dizzy," one boy said after seeing a monarch's zigzagging flight. Watch for a change when fall migration begins. "Directional flight" is a clear sign that migration is underway. Monarchs will fly in a straight line with a southbound bearing.
Fall Migration Only Two Months Away!
Sometime in August, the first monarchs will begin their journey south to Mexico. In northern latitudes, monarchs enter diapause in August, too. "August 15th is the clear cut-off date in Minnesota," says monarch expert Dr. Karen Oberhauser. Her experiments and field observations have consistently shown a shift to diapause on that day.
See You in August!
Watch for the first Fall Migration Update on August 25, 2011. Meanwhile, carpe diem!
