After honing their felting skills on the passion vine flower and buds, our fabrication artists Jeff and Barb started working on felting a bunch of Zebra Longwing caterpillars of various sizes. These (adorable!) caterpillars will find a home on the huge passion vine at the heart of our new Discovery Zone, as the actual Zebra Longwing butterflies use several species of passion flower vines as host plants.
