Often found at the campus area of which divided into two kinds of habitat, urban forest and grassland (old agricultural area that has become naturalized again). See that one in my faculty.
Just love to see this guy become a toys of a cat (#4). I went near them, the cat look at me, and then continue to fight. Some second next, this guy might be bit the cat and the cat walked away from that snake. I saw the cat vomit some white thick liquid from his/her mouth. The cat walked away again and I captured this guy stopped his/her moving. Anyway, I can't find the ID so I put the possible genus on the common name box!
