The monarch butterfly is famous for its multi-generation migration:
◦ from their ❄ wintering grounds in the mountains of central 🇲🇽 México,
◦ following the 🌱︎ new growth and ⚘❀ spring flowers of
milkweed genus Asclepias and related genera
— the only host plant on which monarch's ⚫︎ eggs and 🐛︎ larvae will grow and survive,
◦ north through Texas, and much of the 🇺🇸 USA then 🇨🇦 Canada,
◦ ☀︎ summering in a surprisingly-large areas of these two countries,
◦ before following the late-season flower nectar back to their ❄ wintering grounds.

What an amazing story!
Other monarch populations have different migration patterns. In areas with year-round flower nectar and milkweed plants, monarch butterflies can live and reproduce year-round, and thus do not migrate at all!
🚼︎ For kids! Enjoy this video of 🇲🇽 Mexican folktale The Butterfly/La Mariposa, that explains why butterflies do not live in houses, and why they migrate. Story told en español and in English.
