Wulai is one of the few regions in Northern Taiwan where the rare Aristolochia butterfly species can still be observed in a semi-wild environment.
The garden layout utilizes specific nectar-rich flora to maintain a self-sustaining ecosystem without the need for artificial enclosures.
The high humidity and mountain fog of the Wulai area create ideal conditions for the host plants required by local caterpillars.
The park serves as a critical study site for researchers monitoring the impact of climate shifts on butterfly migration patterns in New Taipei City.
Hu-die Park, or the Butterfly Garden, is a specialized ecological site in the Wulai District focused on the conservation and observation of endemic Taiwanese butterfly species. It serves as a natural habitat rather than an enclosed conservatory, featuring native host plants that attract various local lepidoptera. The park is situated within the Wulai mountain region, a landscape defined by its temperate rainforest climate and proximity to the Nanshi River. Educational displays throughout the grounds identify common local species, including the swallowtail and morpho-type varieties. The site functions as a micro-climate corridor, facilitating the migration and breeding patterns of butterflies throughout the warmer months. It provides a pedestrian-oriented environment designed to minimize human disturbance to fragile insect life cycles.
The central observation clearing where floral density is highest and lighting allows for clear insect silhouettes.
Wear long sleeves and trousers to protect against mosquitoes and ticks, which are prevalent in this humid forest environment.
Bring a macro lens or camera with a high zoom capacity, as butterflies are sensitive to sudden movements and are best captured from a distance.
Avoid using heavy perfumes or scented insect repellents, as these can deter butterflies from landing nearby.
Do not wander off marked trails, as the terrain is prone to slippery moss and steep drops.
Best visited between April and September; activity is significantly lower or non-existent during the cooler winter months.
Maintain a quiet volume and move slowly to avoid startling the insects; do not handle or touch the butterflies.
