Puli Butterfly Valley is a seasonal butterfly-watching site in the Wugonglun hills of Puli Township, Nantou County, where migrating purple crow butterflies gather each spring along Taiwan's butterfly corridor. From the 1960s into the mid-1970s, Puli was a hub of Taiwan's butterfly-specimen export industry — with close to 47 processing shops in town handling more than 20 million butterflies a year — helping earn Taiwan the nickname 'Kingdom of Butterflies' and leaving behind a rich local butterfly culture.

From the 1960s into the mid-1970s — Taiwan's peak era for the butterfly-specimen trade — Puli alone had about 47 processing shops, handling more than 20 million butterflies a year sent in from across the island; Taiwan's total specimen-export value once topped US$30 million, making it the world's leading supplier and earning it the nickname 'Kingdom of Butterflies.' Purple crow butterflies overwinter mainly around Maolin in Kaohsiung and pass through the Puli basin during their spring migration north.

Highlights of Puli Butterfly Valley

Taiwan's purple crow butterflies overwinter each autumn and winter in places like Maolin in Kaohsiung, then migrate northward along the butterfly corridor as temperatures rise in spring. The Puli basin is a key waypoint on that migration route. The hills of Wugonglun, with their sheltered terrain and abundant plant resources, form a valley where butterflies briefly congregate. During migration season (roughly April to May), clear mornings are when observation density is highest — tens of thousands of butterflies in flight is a genuine natural spectacle.

Puli's connection with butterflies goes beyond modern nature observation. After Taiwan's restoration, from the postwar years into the 1970s, Puli was the world's largest center for butterfly specimen exports. Butterfly craft products were marketed to Europe and the United States, driving the local economy. That era has passed, but the deep bond between Puli and butterflies remains an important part of local cultural identity.
