Monarch Butterfly  Migration

Mass Arrival at the Sanctuaries

November 13, 2005

As thousands upon thousands of butterflies reached the El Rosairo sanctuary last Saturday, Dr. Carlos Galindo-Leal snapped the spectacular images below.

“Ontario! Ohio! Quebec! Minnesota! Maryland! Michigan!” we would hear, if each butterfly could name its home state or province as it completed the long migration.

Maybe your own butterfly is pictured here! Or one that you saw flying overhead during migration.

  How Many Monarchs in a Single Photo? (Let's Estimate!)

A Picture is Worth a Thousand Words
There is much to learn by looking closely at a single photo. What do you notice? What do you wonder? Dr. Lincoln Brower has been studying monarchs for over 50 years. Here’s what he saw, and what he wondered:

“You can see monarchs dotting the sky in lines...I have seen this before.....I am convinced they follow each other during the fall migration.....How they do this is a grand question......,”

Dr. Brower wrote. His writing trailed off the way his mind follows questions about monarch butterflies.
