Monarch Butterfly (Danaus plexippus): Monarch butterflies undertake a multigenerational migration spanning 3,000 miles from Canada and the U.S. to central Mexican forests. No single butterfly completes the full round trip; instead, successive generations advance northward each spring and summer. The final generation, born in late summer, lives up to eight months and flies south to overwinter in oyamel fir trees. There, millions cluster together, creating a breathtaking spectacle. They rely on environmental cues and a sun compass for navigation. Habitat loss, climate change, and pesticides threaten their survival. This migration is a fragile marvel of timing, genetics, and instinct, symbolizing the delicate balance of nature.
