SANTA BARBARA, Calif. -

The Santa Barbara Museum of Natural History is celebrating the return of 'Butterflies Alive.'

The popular exhibit only happens once every two years.  The exhibit opened on Saturday, May 17th and will run until September 7th.

'Butterflies Alive' offers visitors the chance to walk in a garden where more than 1,000 butterflies are flying free.  Some of the butterflies are native to the Santa Barbara area, including , the Monarch, Painted Lady, and Western Tiger Swallowtail.

Luke Swetland, is the President and CEO of The Santa Barbara Museum of Natural History. He said the exhibit is constantly evolving and is one you don't want to miss. "Every day for four months, it's a living exhibit.  It will be different.  Over the course of the summer the butterflies that are here will change. So it really is the place to keep coming back to and enjoy over and over again," he said.
