Monarch ButterfliesA Butterfly Invasion
|
 |
It's a sight to behold! Thousands of Monarch butterflies cluster in eucalyptus groves and settle on pine trees all along the California coast. They return every year from as far away as Canada to escape killing winter temperatures.
The Monarch butterfly migration begins in mid-October, and by late November the groves are full of roosting butterflies. In late February, they begin to leave the groves in search of milkweed plants where they can lay their eggs. And by March, most have moved on.
There are about 200 sites along the California coast where these butterflies congregate. The following sites are some of the best locales accessible to the public. They're listed from north to south.
When visiting a butterfly grove, please be aware that when the temperature is below 55 degrees the butterflies are unable to fly. When it's below 40 degrees, they can't even move. So be careful not to disturb them. On warmer days, you may find Monarchs on the ground sunning or drinking. So watch your step!
