Raise Your Own Butterfly & Caterpillar
Experience the wonder of transformation step-by-step. Feed, mist, clean, and guide your specimen safely to flight!
Day 3: The Microscopic Egg
The size of a pinhead! Keep humidity between 65-75% using the mist spray bottle so the egg doesn't dry out.
Monarch Butterfly
Danaus plexippus
Fresh Common Milkweed Leaf
Stores milkweed cardenolide toxins inside body tissues, making it foul-tasting and poisonous to hungry birds.
Monarch caterpillars grow 2,000 times their birth weight in just 12 days—like a human baby growing as big as an elephant!
Always release newly emerged butterflies on warm, sunny mornings (above 65°F / 18°C) near pesticide-free native nectar plants so they can fuel their maiden flight!
