Eastern black swallowtail butterfly: Third larval instar: Closeup of the head of the eastern black swallowtail larva, a day before entering its pupal stage. As a defense mechanism, the red markings and yellow "horns" on its head become more prominent when the larva is threatened.; Format: image/photograph

Butterfly metamorphosis: This is an integrated lesson which is introduced using the book The Very Hungry Caterpillar by Eric Carle. Butterfly metamorphosis is explored through art, math, and writing.; Format: lesson plan (grade 1–2 Visual Arts Education, English Language Arts, and Science); By Laura Byers.

Eastern black swallowtail butterfly: Third larval instar: The larva on a flowering parsley plant.; Format: image/photograph

Eastern black swallowtail butterfly: Third larval instar: Thirteen days out of the egg, the larva is growing rapidly.; Format: image/photograph

Eastern black swallowtail butterfly: Third larval instage: Here, the larva's maturing structure is visible. The larva is now 10 days out of the egg.; Format: image/photograph

Eastern black swallowtail butterfly: Third larval instage: Fourteen days out of the egg, the larva leaves its food source in search of a place to pupate (become a chrysalis).; Format: image/photograph

Eastern black swallowtail butterfly: Third larval instage: As it grows, the larva is able to move easily from plant to plant in search of more food, as it does here.; Format: image/photograph

Eastern black swallowtail butterfly: Larva, first instar, day 1 after hatching: The first larval instar, or stage of the caterpillar, looks nothing like the later stages.; Format: image/photograph

Eastern black swallowtail butterfly: Second larval instar: The second larval instar, or stage of the caterpillar, develops the familiar stripes and markings. This larva is seven days out of the egg.; Format: image/photograph

Eastern black swallowtail butterfly: Chrysalis: With the front part of its body suspended by a pair of threads from the underside of a plant stem, the butterfly larva becomes a chrysalis.; Format: image/photograph

Eastern black swallowtail butterfly: Forming a chrysalis: The larva attaches itself by a pair of threads to the underside of a stick, branch, or leaf, and assumes a C-shape as it prepares to form a chrysalis.; Format: image/photograph

Spiders and monarchs and bees, oh my!: Exploring the world of insects and spiders can replace children's fear with fascination.; By Linda Dow.

An integrated lesson comparing the butterfly and frog life cycles: Students will build on their prior knowledge about the butterfly life cycle to compare and contrast the life cycles of butterflies and frogs. Students will locate butterflies on the school grounds and create pictographs and models of fractions to explain their findings mathematically. Students will also use a variety of resources to read about and study the food, space and air needed by butterflies and frogs to grow. They will create visual and written products to demonstrate their findings.; Format: lesson plan (grade 2 English Language Development, Mathematics, and Science); By Martha Dobson and Margaret Monds.

Marvelous metamorphosis: Most kids love insects. This integrated unit will enable students the opportunity to observe, identify, and describe the life cycle a mealworm goes through during his metamorphosis into a grain beetle.; Format: lesson plan (grade 2 English Language Arts and Science); By Pam Maness.
