Researchers in Hong Kong have confirmed a rare chestnut tiger butterfly flew 3,000km from Japan, establishing a new world migration record for the species.
The butterfly, tagged in Fukushima, was discovered by Ling Yuet-fung on December 21, indicating it was 124 days old.
Experts highlighted the impressive physiological capacity of the butterfly, which maintained its flight for over 100 days.
This migration marks only the third recorded occurrence of the chestnut tiger migrating from Japan to Hong Kong.
Researchers encourage the public to report sightings of tagged butterflies to assist in further Danaid Butterfly Research.
