Loretta finds a caterpillar egg on a milkweed plant. She breaks off the leaf and brings it home. Mom won't let Loretta keep it in the house, so she tapes the leaf back on the plant, and watches over the egg. It hatches. It eats the leaf, and more leaves. As the caterpillar grows and molts, Loretta shoos away a bird that wants to eat it. Then a wasp, and even a ladybug. The caterpillar survives. When it forms a chrysalis, a lizard bites it. It heals and eventually a monarch butterfly emerges. In a mixture of pride and sadness, Loretta watches her friend fly away. Plus information on migration, obtaining milkweed seeds for your area, and how to recognize male and female monarch butterflies.
