The large swallowtail butterflies are commonly at peak activity during spring, making April - June the most popular months to visit. Later in the year we see more butterfly species and stages of the butterfly life cycle but less abundance of large butterflies in fight.

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.

• Strollers are not permitted on trails. 

• Pets are not allowed. We love your pets, but please leave them at home.

• No Smoking anywhere on the HBG grounds.
