Monarch Butterfly Migration: Text Features and Structure Practice
The Incredible Journey of the Monarch Butterfly
Imagine a tiny insect, weighing no more than a paperclip, traveling thousands of miles across a continent. This is the amazing story of the Monarch butterfly. These bright orange and black insects are famous for their long-distance migration. Every year, millions of Monarchs fly from southern Canada and the United States all the way to the forests of central Mexico.
A Long Flight South
Monarch butterflies cannot survive the freezing cold winters of the north. Because of this, they must travel south to stay warm. This journey is a great example of a sequence of events. First, as the days get shorter and the air turns crisp in the fall, the butterflies begin to gather in large groups. Then, they use the sun and the Earth's magnetic field to guide them. They fly during the day and rest in trees at night. Finally, after traveling for nearly two months, they reach the Oyamel fir forests in Mexico. Here, the climate is just right—not too cold and not too hot.
The Monarch Life Cycle
A Monarch’s life is full of changes, a process called metamorphosis. The cycle begins when a female butterfly lays a tiny egg on a milkweed leaf. Milkweed is the only plant that Monarch larvae (caterpillars) eat. Next, the egg hatches into a tiny caterpillar that spends all its time eating. After about two weeks, the caterpillar forms a hard shell called a chrysalis. During this stage, its body completely changes. After another two weeks, a beautiful adult butterfly emerges, ready to find nectar from flowers.
Migration Data
Scientists track Monarchs to see how far they travel each week during the fall. The table below shows the average distance traveled by a single Monarch butterfly during its trip to Mexico.
Week of Migration | Average Miles Traveled |
|---|---|
Week 1 | 250 miles |
Week 2 | 310 miles |
Week 3 | 420 miles |
Week 4 | 380 miles |
Glossary
- Chrysalis: The hard shell that protects a caterpillar while it changes into a butterfly.
- Larvae: The wingless, worm-like stage of an insect; caterpillars.
- Metamorphosis: A complete change in form during an animal's life cycle.
- Migration: The seasonal movement of animals from one region to another.
- Nectar: A sugary liquid produced by flowers that butterflies drink for energy.

Section 4: Extended Constructed Response
Prompt: Choose one text feature from the passage (e.g., the diagram, the data table, or the glossary). Explain how this specific feature helped you understand the information about Monarch butterflies better.
- Identify the feature.
- Explain what information the feature provided.
- Explain why that information was easier to understand as a visual feature rather than just as a sentence in a paragraph.
