Insect Metamorphosis
Overview
After reading a story summary about insect metamorphosis, students compare and contrast a butterfly and a moth.
Students explore a Web site that illustrates and discusses the life cycles of the butterfly and moth as well as addressing many other aspects of insect life.
Objectives
Describe the life cycle of a butterfly and moth.
Observe a butterfly and a moth.
Compare and contrast the characteristics of butterflies and moths.
Materials
Steps
- Share the book summary with students and invite them to comment on
metamorphosis. You might ask what the stages of metamorphosis are. Do you think
that the life cycle of a butterfly and moth are different or the same?
- Take students online to visit the University of Kentucky's Entomology for
Kid's Insects All Year feature, at
http://www.uky.edu/Agriculture/Entomology/ythfacts/allyr/ythfacts.htm. This Web
site was created to explore and educate people about butterflies and other
insects, and has a different insect-related topic for each month of the year.
Click on May, for How to Make a Butterfly Garden.
- Review
the stages of metamorphosis with students online. Invite groups of students to
print out a stage. Then have students select a stage to describe. Invite some
students to print out the adult moth and others the adult butterfly as the last
stage.
- Distribute the Insect Metamorphosis Activity worksheet.
Review the directions with students. Then have students
complete the activities. When students compare and contrast the butterfly and the
moth, they might discover some of the following differences:
Butterflies
active during the day
drink nectar
wiry antennae
wings folded when resting
generally more colorful
(because of daytime activity)
pupa stage called chrysalis |
Moths
active during the night
some moths don't eat
fuzzy antennae
wings open when resting
generally less colorful
(because of nighttime activity)
pupa stage called cocoon

Home Connection
Families can explore the life cycle of the painted lady butterfly at the Virginia
Tech Entomology Web site feature, Insects in Motion. Go to
http://everest.ento.vt.edu/~carroll/insect_video_home.html and click on
Butterflies under Life Stage Development. Each family member can draw a
stage of the butterfly's development, describe it, and then make up riddles about
each stage.
Extension
Have small groups of students visit the Butterfly Site Photo Gallery at the USGS
Children's Butterfly Web site. Students can click on
http://mpin.nbii.gov/insects/kidsbutterfly/index.html
to locate and describe
butterflies in their area. Students can hold a class contest to see who can
locate the most butterflies in their area.
