Butterflies favor the Central Coast during winter months
Pismo Beach is home to one of the largest winter Monarch butterfly colonies in the country. An average of 75,000 of these vibrant orange and black butterflies come to Pismo Beach each year from late October to February, having traveled over 1000 miles as far away as Canada, to seek shelter from the freezing temperatures.
Scientists do not know why the Monarchs consistently return to certain wintering sites. Some scientists speculate that the insects are equipped with genetic homing systems that lead them from their summer sites in the Sierras, Florida, Canada and the Great Lakes Region in North America back to their winter locations.
Visitors to the grove of Eucalyptus trees at Pismo State Beach, located on State Highway 1, will be greeted by knowledgeable and well-informed volunteer docents offering daily talks and information on the clusters of butterflies clustered in the limbs of a grove.
On the Central Coast, the Monarchs also winter in Morro Bay. Visitors can see the butterflies at the Morro Bay State Park, typically around campsite 116. The Natural History Museum, located at 20 State Park Rd in Morro Bay, is an excellent resource for information about Monarchs.
