A monarch butterfly sips nectar from New England aster. Decreasing day length and temperatures, along with aging milkweed and other nectar sources, trigger the birth of the super generation and their epic migration.

Aug 21, 2019 · The migration story of monarch butterflies (Danaus plexippus) is an epic adventure that spans generations and thousands of miles.
