Tsai has created a precious photographic record of the butterflies of Taiwan. Following the establishment of the national parks, Tsai became sought after as a compiler of butterfly ecology guides and field guides. Tsai has published many books, among them The World of the Butterfly in Taiwan.
幸虧蔡百峻多年來為台灣蝴蝶留下珍貴影像紀錄，隨著國家公園相繼成立，蔡百峻成了蝴蝶生態簡介或賞蝶指南的最佳主持人選，相繼出版了《台灣的蝴蝶世界》等多種叢書。
