It's March! The days are getting longer and temperatures are rising in the monarch colonies in Mexico. "Within the month—a relatively short time—the butterflies will vacate their winter haunt and begin the recolonization of North America. An ambitious project, to be certain," says Dr. Bill Calvert. Meanwhile in Texas, observers have been watching for milkweed to push up from the soil. The first was seen this week. What timing! We expect Texans to report the first monarchs from Mexico any day. Get ready to track the spring migration! >>
The monarchs that are about to migrate north are survivors. They have survived without eating—and without being eaten! Did you know that monarchs have enemies at their winter home in Mexico? Let's meet them and find out how monarchs avoid them.
