Spring and Summer

Spring and Summer

With the coming of spring, the monarchs join the western migration, spreading out through the Central Valley, into the Sierras, and northeast to the Rocky Mountains, laying eggs as they go. monarchs born in the spring and summer move rapidly through their life cycle, flying further north and east with each succeeding generation. As many as five generations of monarchs may continue northward, until the shortening daylight once again reverses the direction of the migration.
