Which butterfly is noted for long-distance migration to California and Mexico?

• A. Monarch Migration
• B. Painted Lady
• C. Swallowtail
• D. Blue Morpho

Answer: (A)

Long-distance seasonal migration to specific overwintering grounds is being tested. The monarch butterfly is renowned for its annual journey from much of the United States and southern Canada all the way to central Mexico, with some groups also using wintering sites in southern California. This migration is extraordinary not because a single butterfly makes the entire trip, but because generations follow one another across the landscape, guided by environmental cues and nectar sources, and then return north as adults in spring. The result is a well-known, predictable pattern of long-distance movement to California and Mexico, which is why this option fits best. Other butterflies do migrate, but not with the same long-distance, geographically focused pattern to those destinations, or they are more tropical and localized in their movements.
