Upper head is uniform dark olive brown and the sides are lighter in color; the labials are not black-edged. Upper body and tail are uniform dark olive to gray brown, with dark-edged scales mainly posteriorly resembling a net pattern. There are about 9 indistinct or grey longitudinal stripes along body. Juveniles have transverse rows of white spots across body anteriorly. Ventral head is creamy white to yellow.

生態描述

此種半樹棲蛇類日夜皆會出沒,通常在森林和農田附近的地面或樹上棲息,也有可能出現在人類居住的區域。牠以青蛙、蜥蜴、蛇、鳥還有這些生物的蛋與小型哺乳動物為食。母蛇在 5-6 月產下每窩約 8-12 枚的卵。初生幼蛇長約 26cm 。細紋南蛇被捕捉時會非常緊張,牠可能會強烈的扭動身軀來逃脫捕捉者,馴養幾天後仍然有可能會螫咬抓牠上手的人。

遇到蛇時,可以從牠是否有大眼睛、棕橄欖色的尾巴與頸後至身體前段適否有淺色細橫紋來判別是不是細紋南蛇幼蛇(只限定幼蛇、成蛇無此細紋) (Source)

 

學名與俗名

Ptyas 是古希臘的傳說 - 關於毒液被吐近男子眼睛;

korros: 根據 Stejneger (1907), korros 是爪哇語中的一種蛇,應該是指 Coluber melanurus (此名稱有個曲折的故事,可能是指 Coelognathus)、與 Schlegel,在命名 Coluber korros (現在的 Ptyas korros[細紋南蛇])時誤用的名稱。

細紋南蛇、灰鼠蛇、黃梢蛇、過樹龍。
