The large swallowtail butterflies are commonly at peak activity during spring, making April - June the most popular months to visit.

Please visit our Butterfly Information page to plan your visit relating to butterfly behavior and enhance your experience.

The weather, season, time of day, and butterfly species all play a role in guessing what butterfly activity to expect. On certain days of the year, we could be considered more of a caterpillar or chrysalis garden—the species and number of butterflies in flight constantly fluctuate.

• Do not pick plants or flowers.

• Do not touch caterpillars/butterflies and leave other animals as they are.

• Stay on paths.
