2015 Butterfly Festival Design Contest

Our annual Butterfly Festival, held on the grounds of our 930-acre Watershed Reserve, has been a popular family event attracting around 3,000 visitors every summer. This year will be especially spectacular as we unveil the NEW Watershed Center and Kate Gorrie Butterfly House. Also featured will be live music, local artisans, delicious food, an insect and butterfly zoo, fun and educational enviro-zones, and our famous Butterfly and Bug Parade. (Don’t forget your costume!)

Flying Colors 2014
2014 “Flying Colors” Logo by Annalise Hollosy

We invite New Jersey high school students to submit designs for the 14th Annual Butterfly Festival logo. The event theme is “COME FLY WITH US”, representing not only the flight of our native winged creatures, but also the transformative changes that have taken place at the Watershed over the past year. We suggest artwork depicting flying and fluttering native butterflies, insects, or birds; we also invite you to include the design of our new Butterfly House in your design. The winning submission will be prominently featured on event t-shirts, in publicity and press materials, and will be framed and hung in our new Watershed Center.
