生態描述

此陸棲日行性蛇類,喜歡棲息在水源充足的低地平原或是丘陵地帶。牠以捕食蟾蜍、青蛙還有魚維生,偶爾也會捕捉蚯蚓和壁虎。母蛇魚春末產下每窩 4 -16 枚的卵,每顆卵長約 2.5cm 寬約 1cm 。花浪蛇有著溫和的性格,並且通常不會有攻擊的傾向或螫咬的行為: "此種蛇類最著名的就是牠的無害,各種牠不同的俗名都表達出牠是一種友善的蛇類。甚至民間傳說花浪蛇是土地公的兒子,因而有[土地公蛇]的俗稱,告誡大家不能打死牠。通常牠是在日間出沒的,假如有大量的食物可以捕捉,也會在夜間出來捕食。經常出沒在水塘邊蛙類隱匿的地方,可是很少會進入水中。當遇到人類時會飛快的鑽進附近的草叢躲藏,被捕捉時就算刻意激怒牠通常也不會有反擊的行為。" (Source)
