Monarch Butterfly Migration and Metamorphosis Journey

In Texas, a monarch butterfly searches for milkweed to lay her eggs, facing challenges due to farmland and pesticides. She finds a suitable backyard in Austin, lays her eggs, and dies. Her caterpillars hatch, grow by consuming milkweed, and use its toxins for defense. They transform into butterflies, continuing the migration cycle.
