Monarch Butterfly Migration Update: May 23, 2003
News From the Migration Trail
Comparing Three Spring Migrations: 2001, 2002 and 2003 On the maps below, compare this spring’s migration to those of the previous two years. Notice how far north the migration had traveled by this time in 2001! That year, the monarchs lagged behind in the south in early spring (notice location of gold dots), then surged northward quickly (red dots). What similarities and differences do you notice between all three seasons?
Milkweed Emerging Along the Migration Trail Please help monitor the spring emergence of the monarch's food plant across North America. You'll be amazed at the close connections the migration and this all-important plant. Please REPORT when your milkweed grows!
Stay Tuned: The Monarch Migration Continues! Other Journey North migrations have come to an end, but we'll continue to track the monarchs until they've expanded across their entire breeding range. This normally takes until mid-June. Please Help: YOUR Monarch Sightings Are Important Even after the first monarchs have been reported from your state or province, we want to hear from YOU when you see YOUR first! The number of sightings reported reflects monarch abundance, so your observations will continue to be important.
