It is a larve. Mealworms molt as they grow. They also change colors as they grow. Molting - the shedding of the tough skinlike cuticle so the mealworm can grow. The mealworms molt about 5 times before it changes into a PUPA! PUPA The mealworm does not move in this stage. Inside, the mealworm is turning into a BEETLE! ADULT After 2-3 weeks the PUPA molts for the last time. It then emerges as an adult beetle. The ADULT… • Lives for about 30 days. • It can survive on bran and an apple or potato for moisture. • Flaps its wings when it is ready to mate. • Lays eggs a few days after mating. Waxworm Life Cycle • Egg • Larva • Pupa • Adult moth Waxworms will eventually turn into Wax Moths Waxworms make SILK This helps the larve walk and is used to build a protective cocoon After gorging itself as a chubby white larva, the waxworm is ready to pupate. The waxworm rests and transforms into pupae after the larve spins a cocoon. After about 2 weeks the adult moth emerges. The adults do not eat or drink! After mating the females lay their eggs and die. Life Cycle of a Painted Lady • Egg • Larva - caterpillar • Pupa - chrysalis • Adult butterfly *The series of transformations is COMPLETE METAMORPHOSIS Painted Lady caterpillars turn into BUTTERFLIES The painted lady constructs a chrysalis when they pupate. A chrysalis is a smooth plasticlike protective cocoon. The painted lady emerges from the cocoon after about 10 days. A beautiful painted lady butterfly emerges. The butterflies… • Are very strong fliers. • Live well on sugar water. • Live up to 30 days. Mrs. Daniels Hello Young Scientists! I am a first grade teacher at Jacksonwald Elementary in Reading, Pennsylvania. I have a husband, Jason and two children, Josh and Rian. We all love the outdoors and enjoy looking at nature and all of her creatures. This is one of my favorite science units to teach to my first graders. Our favorite part is watching the butterflies come out of their cocoons. We have so much fun letting the beautiful butterflies go at the end of the unit.
