Gunung Palung National Park (GPNP) has butterfly diversity. However, there is a lack of information about butterflies in Gunung Palung National Park as a learning resource. This article reports on the species of butterflies in three different ecosystems from GPNP and the potential of insectariums as a source of learning biology. There are two stages of research, first to examine the species of butterflies from GPNP in the Freshwater Swamp Forest, Alluvial Forest, and Lowland Granite Forest ecosystems. Second, to examine the potential of butterflies insectariums as a learning resource. The location of the research was determined by purposive sampling. Butterflies are caught by sweeping technique. Collecting data on potential learning resources using observation, documentation, and questionnaires. The results found 119 individuals from 39 butterfies species. Based on the aspects of access, safety, time, cost, clarity of potential, suitability of learning objectives, clarity of material objectives, and clarity of information, it shows that the potential of the butterfly insectarium is worthy of being used as a learning resource, especially in biology subjects, namely Biodiversity, Classification of Living Things, Animalia, and EcologyTaman Nasional Gunung Palung (TNGP) memiliki keanekaragaman kupu-kupu. Namun, informasi tentang kupu-kupu di Taman Nasional Gunung Palung masih kurang sebagai sumber belajar. Artikel ini melaporkan spesies kupu-kupu di tiga ekosistem berbeda di TNGP dan potensi insektarium sebagai sumber belajar biologi. Ada dua tahapan penelitian, pertama untuk mengkaji spesies kupu-kupu dari TNGP di ekosistem Hutan Rawa Air Tawar, Hutan Alluvial, dan Hutan Granit Dataran Rendah. Kedua, mengkaji potensi insektarium kupu-kupu sebagai sumber belajar. Lokasi penelitian ditentukan secara purposive sampling. Kupu-kupu ditangkap dengan teknik sweeping. Pengumpulan data potensi sumber belajar menggunakan observasi, dokumentasi, dan angket. Hasilnya ditemukan 119 individu dari 39 spesies kupu-kupu. Berdasarkan aspek akses, keamanan, waktu, biaya, kejelasan potensi, kesesuaian tujuan pembelajaran, kejelasan tujuan materi, dan kejelasan informasi menunjukkan potensi insektarium kupu-kupu layak dijadikan sebagai sumber belajar khususnya pada mata pelajaran biologi yaitu Keanekaragaman Hayati, Klasifikasi Makhluk Hidup, Animalia, dan Ekologi
