We look forward to seeing you on August 5, 2023 for the 23rd Annual Butterfly Festival! 

A big thank you to the 2,000 people who attended the 22nd Annual Butterfly Festival in 2022.

We hope everyone enjoyed the tours of the Kate Gorrie Butterfly House, Insect Zoo, Bug & Butterfly parades, crafts, delicious food, hay rides and more! We thank the Rizzo’s Wildlife Show,  

Currier’s Magical Mania of Princeton’s Bubble Show,  and Travis Gale of Eyes of the Wild Show.

The Kate Gorrie Butterfly House opens in the spring at The Watershed Institute, 31 Titus Mill Road, Pennington, NJ. Our butterfly house is open from dawn to dusk and you will have a chance to observe the endangered monarch butterfly and the state  butterfly, the black swallowtail.

We want to express our appreciation for our visitors, volunteers, donors, vendors, sponsors and others who made our 2022 event so magical.
