Respiration is a necessary function for all living, but it is accomplished in vastly different ways. How a caterpillar becomes a butterfly: Metamorphosis, explained. A misconception to be explained would be how caterpillars become butterflies Most children understand that they came from their mother, and apply the mammal style of reproduction to other living things. Our homes are dry environments, and insects and spiders seek out moisture. You can't blame a kid for thinking that. Children develop their early understanding of insects from books, movies, and the adults in their lives. For species with such different developmental forms, youve suddenly created a competitive-free space, says Katy Prudic, an entomologist at the University of Arizona in Tucson. Plants require nutrients in a chemical form, for instance, while more advanced life forms have stomachs that are able to convert raw ingredients into the necessary nutrients. Ask students what they would like to learn about the life cycle of a butterfly and fill in the "W" column. 1. Other species, such as grasshoppers and dragonflies, experience incomplete, or simple, metamorphosis, which involves three life stagesegg, larva or nymph, and adult or imago. Image by CJ Kazilek. 13.

This is also called a caterpillar if the insect is a butterfly or a moth. The old skin splits, revealing the new skin underneath. There is no question that we need to preserve existing habitats, but we can also begin to reestablish habitats and increase diversity by integrating native plants into the landscape, both on a large scale and in our own backyards. A whopping 75 percent of known insectsamong them bees, beetles, flies, and mothsdevelop in four stages: egg, larva, pupa, and adult.
