Watch for Fall Monarch Butterflies

When you see a monarch, we want to know about it. Monarchs migrate from August to November. Please report at least once a week, as long as monarchs are present. Print

Watch for Nectaring Monarchs
One of the surest ways to see migrating monarchs is to plant flowers to attract them. Monarchs may drop from the sky for the food they need during fall migration.

"We planted our garden in the middle of a city and they found us!" a teacher wrote from Minnesota.

Watch for Flying Monarchs
You'll know a migrating monarch if you see one that seems to be flying with a purpose, and traveling in one direction. This is called "directional flight."

"Every monarch was traveling in the same direction, as if they were following a road in the sky!" wrote a New York observer.

Watch for Roosting Monarchs
At night, monarchs come down to rest and cluster together in overnight roosts. A roost may have a handful of butterflies or far too many to count.

"We had 200 to 300 monarchs in the large trees in our schoolyard," wrote students from Ontario.
