Let’s Explore Hong Kong Butterflies Together

Though tiny, Hong Kong has more than 260 species of butterflies, which is a tenth of all butterfly species in China, and as a result has been called a “butterfly heaven”. Around 40% of Hong Kong’s land area is designated as country parks, and so protected by law. However, many prime butterfly areas still lack adequate protection.

Established in 2008, “Butterfly Surveyor*” is the first Butterfly Surveyor group comprising members of the public. The group specialises in collecting data on butterfly species and ecological data. Each year, “Butterfly Surveyor “recruits general public as new members, after they completed trainings and assessments, they will become qualified “Butterfly Surveyor”. Until 2018, “Butterfly Surveyor” has 322 qualified members, who have been monitoring regularly at designated sites: San Tau – Lantau Island, Luk Keng – North District, Wu Kau Tang – Tai Po, Lam Tsuen – Tai Po (She Shan and Ng Tung Chai), Yuen Tun Ha – Tai Po, Sha Tau Kok, Sham Chung and Yung Shue O – Sai Kung, Pak Sha O and Lai Chi Chong – Sai Kung, Mui Wo – Lautau Island, Ho Sheung Heung / Long Valley / Lok Ma Chau , Tai Lam Country Park (Kam Tin) and Lung Kwu Tan - Tuen Mun.

Butterfly Surveyors are recruited annually in Febuary, please refer to We love Butterflies Net for further details.

All theory lessons and the assessment of Butterfly Surveyor 2019 have successfully completed. Qualified butterfly surveyors will receive an email about the details of the outdoor trainings and route training. The first outdoor training will be held on 28 April (Sun).
