A recent study found that painted lady butterflies (Vanessa cardui) don’t have significant genetic differences between short- and long-distance migrants.
Key findings of the study
A "single migratory cycle" refers an animal (like a bird) makes one round trip between two places—usually moving from a breeding area to a wintering area and back—due to seasonal changes or food needs.
