The Watershed Butterfly Festival, presented by the Stony Brook-Millstone Watershed Association, will teach families about their local environment. Kids can get face to antennae with butterflies and other insects at the insect zoo, and families can explore nature on hayrides, walks, and at the festival's interactive enviro-zones. After learning all about a butterfly's lifecycle and rambling along on a trail, guests can take in the fest's butterfly parade. Other entertainment will include live music from Grammy-nominated kids' artist Miss Amy and classic rock from The Dadz. Food and art will also be available from local artisans.
