The monarchs are on their way. Get ready to track spring migration.

"We're seeing migrators everywhere, all over the valley village where we live, as well as the busy streets of nearby Zitacuaro," wrote Ellen Sharp.

"I live in Zinapecuaro, Michoacán, two hours from the overwintering sanctuaries. I spotted my first monarch in my yard at 1 pm and two more at 2 pm. They are definitely moving north."

Entering Texas
A worn and faded monarch reported on Tuesday signals that the migrants from Mexico are entering Texas. Presumably many had already arrived but it has been difficult to tell because monarchs were reported all winter as far north as Austin, at latitude 30°N. Watch for a clear wave of advance during the next week. The leading edge of the migration typically reaches northern Texas by the end of March.
