The History of Butterflies at Ellwood (Goleta)
How Do Monarchs Know Where to Go?
Butterflies in the Grove
Learn the best ways to view the monarchs when you visit the grove.
Monarch caterpillars only eat milkweed. Eating milkweed is what makes monarch caterpillars and butterflies toxic.
The Goleta Butterfly Grove (also known as the Ellwood Main Monarch Aggregation Site) is one of the largest overwintering sites in California.
Male monarchs have a dot on each of their hind wings. This is a special sac that helps them attract a mate.
Wild monarchs lay 300-400 eggs in their lifetime
Migrating monarchs live up to nine months. Monarchs that don’t migrate live two to five weeks.
Migrating monarchs can fly at speeds of up to 50 km/hr.
The monarchs that spend their winter at Ellwood have never been to Goleta previously. They are five generations removed from last year’s visitors.
Monarch butterflies that migrate to Goleta come from the western Rocky Mountains.
