SANTA BARBARA, CA— A beloved summer tradition returns when Butterflies Alive! reopens at the Santa Barbara Museum of Natural History on May 23. This experience is the Museum’s most popular exhibit and has been voted into the top three butterfly gardens in the nation by the USA TODAY 10BEST Readers' Choice Awards. The top two are in Virginia and Florida, making this local favorite the best butterfly garden west of the Mississippi. Guests enter an immersive habitat buzzing with life, discovery, and connection. The exhibit runs through September 7.

The butterflies on view begin life in Costa Rica, and arrive at the Museum thanks to a partnership that supports sustainable livelihoods and conservation in one of the most biodiverse places on Earth. Costa Rica Entomological Supply (CRES)—a leader in sustainable butterfly farming for over 40 years—coordinates a network of small, family-run butterfly farms that provide both economic opportunity and environmental benefits for Costa Ricans. Using best practices promoted by CRES and the International Association of Butterfly Exhibitors and Suppliers, the farmers care for adult butterflies and raise their offspring from eggs, to caterpillars, into the pupal stage. CRES coordinates the distribution of pupae around the world for exhibitions like the Museum’s. The Museum receives shipments of hundreds of pupae at a time, which are visible in the emergence chamber in Santa Barbara Gallery. Once they’ve emerged as butterflies, they live out their adult lives in the Sprague Butterfly Pavilion.

A Costa Rican butterfly farm’s footprint is often very modest: “Many people think that a butterfly farmer is this guy with a big piece of land,” says CRES Commercial Manager Sergio Siles. Actually, “it’s a guy in the backyard! They do magic there.” This unique cottage industry reflects Costa Rica’s broader commitment to conservation. As Siles explains, “We shifted as a country, the conservationist mindset that we have. It’s a highlight of the whole country.”

The Museum’s Director of Guest Experience Zsembik experienced Costa Rican conservation and butterfly farming firsthand during her recent visit to CRES headquarters. She was impressed by the diligent scientific work of the Costa Rican farmers and the commitment they make in staking a deliberate personal investment in the conservationist national identity. For Zsembik, the value of the connection is clear: “In choosing CRES as a supplier, the Museum supports people and ecosystems in Costa Rica,” she says, “and in supporting our exhibit, you’re making that choice possible.”

Back in Santa Barbara, those global efforts come to life in a vibrant space designed to support butterflies’ natural behaviors. Seeing these moments up close helps visitors better understand the challenges butterflies face in the wild and the role people can play in supporting their survival. Each day, close to 1,000 live butterflies take flight inside the lush pavilion. Sunny days see a lot of fluttering, while June gloom encourages butterflies to be still for a snapshot. Guests stroll among more than two dozen Costa Rican species, observing natural behaviors up close while connecting with the beauty and fragility of these remarkable insects.

Butterflies Alive! requires a $3 ticket in addition to regular Museum admission. Museum Members enjoy free admission to both the Museum and the pavilion.
