Life Cycle: Metamorphosis DiagramLesson Eight extensionActivity Sheet 4Objective: Follow-up activity on the life cycle of a butterflyButterflies, beetles, and ants undergo complete metamorphosis. Insects that undergocomplete metamorphosis have a stage in their lives when they transform from larva toadult. This transformation stage is called the pupal stage. Many other insects (grasshoppersand true bugs) undergo incomplete metamorphosis. Insects that undergo incompletemetamorphosis look like a tiny adult when they hatch and grow bigger and bigger throughtheir lives. Those insects do not have a pupal stage.Butterfly and moth larvae (caterpillars) hatch from an egg. The larva eats, grows, andsheds its exoskeleton (molting) as it increases in size. The larva then begins the stage oflife called a pupa. The larva (caterpillar) turns into a chrysalis if it is a butterfly or weaves acocoon if it is a moth. The pupa then changes into an adult. It grows wings, different legs,a different mouth, antennae, and different eyes. When the adult emerges from this stage itsearches for a mate. The adult butterflies and mothsof most species only live a few weeks.Female butterflies and moths lay eggs only on plants that will be the correct food for thelarvae when they hatch.Label the images below as either egg, larva, pupa, or adult.EGG: The first stage in the life of a butterfly or moth. An egg hatches into a larva.LARVA: An immature butterfly or moth. The larva is also often called a caterpillar.PUPA: The stage in the life of a butterfly or moth when it changes from a larva to an adult.ADULT: The stage in the life of a butterfly or moth when it has wings, finds a mate, andreproduces.Florida Museum of Natural Historyhttp://www.flmnh.ufl.edu39
