This Classroom kit allows each student to witness the day-to-day development and ultimate transformation of their very own caterpillar. The kit includes a 24-inch Butterfly habitat and a prepaid voucher that can be redeemed when you are ready to start the project. Upon redeeming your voucher, you'll receive 33 live caterpillars, each with their own growing containers and food. This will allow each student to watch their own baby caterpillar transform into a beautiful butterfly over a period of 3 weeks. The large, collapsible Butterfly Pavilion habitat also includes convenient hook and loop fasteners that make it easy to attach the lids and chrysalid inside the habitat.
