Migration Highlights

Warm Air — and Monarchs Move Northeast
An unusally warm air mass spread across the eastern half of the United States and southern Canada during the past week. Just look at Monday's temperature map. Northern regions were even warmer than Texas!

Monarchs flew and blew northward with this warm air according to our observers. People everywhere were surprised by the monarchs' early arrival and amazing ability to find milkweed:

  • While students were outside during a fire drill at Washington School in Summit, New Jersey, they spotted a monarch laying eggs in the school butterfly garden!
  • An astonishing 125 eggs were layed in a butterfly garden in Pennsylvania on milkweed that was only 3 inches tall.
  • Students in Bridgewater and Somerville, New Jersey both saw their first monarchs this week. "This is so early for us and so exciting," said teacher Cathy Griffin.
  • Add six news states to your list! Monarchs have moved into Indiana, Ohio, Maryland, New York, New Jersey and Connecticut.
  • Predict: When will monarchs appear in the first Canadian Province? Prediction Chart


Monday's temperatures were as warm as mid-summer in the Northeast.

A single monarch butterfly can lay hundreds of eggs. What would happen if every egg survived? Let's see how many monarch generations it would take to reach a billion butterflies. Then explore the limiting factors that keep the monarch population from growing as fast as it could.

Also, find out how you can help scientists learn more about monarch populations. Volunteers are needed to observe monarchs for these projects:
