Rainy, humid weather is required for frogs to lay their eggs. Because winter is southern Taiwan's dry season, the Taipei tree frog is found only in mountainous areas under 1,000 meters in altitude north of Nantou County. Their mating season is from October to April.
青蛙必須在多雨、濕潤的氣候產卵，冬天台灣南部是旱季，所以台北樹蛙只分布在南投以北的一千公尺以下山區，生殖季在十月到次年四月間。
