Highlights: Laying Eggs as They Travel
When you look at the migration map this week, think EGGS. Think about a trail of eggs that stretches at least 1,300 miles, from the overwintering sites in Mexico to a roadside in Arkansas. That's how far the monarchs have traveled.

Think about habitat, too. The monarchs can only lay eggs where they can find milkweed.

And think about time. It's April. This is the last month in the lives of the monarchs that over-wintered in Mexico.

Field Reports from Citizen Scientists: What are observers seeing?

"Two students found a tattered female monarch on the playground at Whittier Elementary in Lawton, OK. They are putting the monarch on some flowers to rest so that it will be able to eat and then fly off," wrote Mrs. Munoz on Monday.

"We have our milkweeds in place! We are looking forward to adding to the data base," wrote teacher Sandra Conroy from Flower Mound, Texas last Friday. Only three days later the monarchs found the milkweed and deposited an egg. She sent pictures to prove it!
