Taiwan, often referred to as “The Butterfly Kingdom,” boasts an astonishing diversity of butterflies, making it a haven for enthusiasts and nature lovers alike. With over 377 recorded species, and some reports suggesting the number exceeds 400, Taiwan stands as a unique hotspot for butterfly biodiversity. In this article, we delve into the reasons behind this abundance, the cultural significance of butterflies, ideal locations for butterfly watching, common species, and the conservation efforts dedicated to preserving these delicate wonders.
Taiwan, The Butterfly Kingdom
Taiwan’s geographical features, including its subtropical evergreen forests and a diverse range of ecosystems, contribute to its rich butterfly population. The island’s concentrated steep mountains offer various forest types, from subtropical lowlands to temperate and alpine or montane forests. This unique combination of factors has earned Taiwan the moniker “The Kingdom of Butterflies.”
Why Does Taiwan Have So Many Species of Butterflies?
Taiwan boasts a remarkable diversity of butterfly species, a phenomenon influenced by its unique geographical location, varied habitats, altitude variation, isolation as an island, mild climate, and a rich array of host plants. Situated in a subtropical region, Taiwan experiences a convergence of tropical and temperate ecosystems, fostering a favorable environment for diverse flora and fauna. The island’s diverse topography, including mountains, forests, plains, and coastal areas, provides different ecological niches that contribute to the evolution of various butterfly species.
The altitudinal variation, ranging from lowlands to high mountain peaks, creates distinct microclimates, influencing both plant and butterfly distributions. Taiwan’s isolation has allowed for the development of unique species through speciation in isolated populations. The island’s mild climate throughout the year supports continuous ecological processes and provides stability for butterfly populations.
Moreover, the abundance of host plants, including a wide range of native species, plays a crucial role in supporting diverse butterfly populations. Some species may engage in migratory patterns, contributing to genetic diversity and the introduction of new genes to different populations. In essence, Taiwan’s intricate interplay of geography, climate, and ecology has led to the establishment of a butterfly diversity hotspot on the island.
Cultural Significance of Butterflies in Taiwan
In Taiwan’s predominantly Han Chinese culture, butterflies hold significant symbolic value. The Chinese characters for “butterfly” (蝴蝶) sound similar to the characters for “good fortune” (福) and “the elders” (耋), making butterflies symbols of good luck and long life. These motifs are commonly found in crafts, paintings, and even buildings.
Indigenous groups in Taiwan, such as the Rukai and Paiwan, incorporate butterflies into their traditions. For example, the Rukai tribe considers wearing a butterfly headdress a great honor granted by the chief, symbolizing swiftness and winning them the title of “lyalivarane” or “butterfly.”
The annual Yellow Butterfly Festival celebrates and protects butterflies and their habitats, featuring performances, butterfly-watching hikes, and ceremonies.
Decades ago, Taiwan’s butterfly abundance even fueled a lucrative trade, with many making their livelihoods selling butterfly specimens and crafts. However, as Taiwan transitioned from an agricultural to an industrial nation, butterfly habitats faced threats, leading to a decline in their population. Conservationists are now actively working to protect and preserve Taiwan’s unique butterfly species.
When and Where to See Butterflies in Taiwan?
The best time to immerse yourself in the beauty of Taiwan’s butterflies is between November and March. This period marks the peak of butterfly activity, with the first flocks gracing the skies around November. As the season unfolds, their numbers gradually increase, creating a mesmerizing dance of colors against the backdrop of Taiwan’s scenic landscapes.

The Meinong district, located 30 minutes away from Kaohsiung, becomes a butterfly haven during late spring and summer. Yellow Butterfly Valley, just four miles northeast of downtown Meinong, hosts over 100 butterfly species, including the prominent yellow emigrant. Late July witnesses a spectacular display, with half a million butterflies covering a few acres of the valley.
On the Butterfly Trail: Zhongshan District, Taipei
Managed by the Butterfly Conservation Society of Taiwan, the butterfly trail off Jiannan Road in the Zhongshan District of Taipei is a 28-acre open butterfly museum. Visitors can observe 149 species of butterflies in their natural habitat along the trail, ending at the National Palace Museum, where butterflies are featured in artistic treasures.
A Garden of Butterflies: Jinshi Lake Butterfly Garden, Kaohsiung Sanmin District
The Jinshi Lake Butterfly Garden, located in Kaohsiung Sanmin District, proudly holds the title of the largest butterfly house in Taiwan. With representatives from 30 different species, including swallowtail butterflies, Pieridae, Nymphalidae, and Lycaenidae, the garden allows visitors to witness every stage of a butterfly’s life cycle.
Purple Flight: Maolin National Scenic Area
Situated at the foot of the Central Mountain Range, the Maolin National Scenic Area hosts the purple-winged common crow butterflies during their annual winter migration from December to March. Conservation efforts have helped rehabilitate the butterfly population, making it a colorful spectacle in the Maolin Valley.
An Overnight Butterfly Bash: Butterfly Valley Resort, Hualien County
The Butterfly Valley Resort, the only accommodation in Fu-Yuan National Forest Park in Hualien County, offers a unique butterfly-watching experience. With over 70 species of butterflies in the valley during peak season from March to September, the resort includes a butterfly eco house and an exhibition room for dedicated butterfly enthusiasts.
Flitting on the Butterfly Highway: National Freeway Bureau Initiatives
In a remarkable venture for nature conservation, Taiwan’s National Freeway Bureau initiated the Butterfly Highway, an innovative project designed to safeguard butterflies from the hazards of vehicular traffic. Spearheaded by the passionate conservationist Chan Chia-lung, this pioneering effort aimed to provide a secure passage for Taiwan’s delicate airborne inhabitants.
The concept was simple yet groundbreaking – erecting 13-foot high nets along sections of freeways to guide butterflies safely above passing vehicles. The goal was to mitigate potential collisions that could pose a threat to these fragile creatures. This thoughtful intervention not only aimed to protect the intricate dance of butterflies but also served as a testament to Taiwan’s dedication to environmental conservation.
The success of the Butterfly Highway resonated far beyond Taiwan’s borders, inspiring similar initiatives worldwide. Countries, including the United States, particularly in places like North Carolina and Minnesota, adopted comparable measures to ensure the safety of migrating butterflies. This global emulation highlights the significant impact of Taiwan’s commitment to butterfly conservation, turning a local initiative into a beacon for environmental stewardship on an international scale.
What Are the Most Common Species of Butterflies in Taiwan?
Taiwan boasts a stunning array of butterfly species, each with its unique characteristics. Some notable examples include:
