Red Color Insect

I saw the red color insect on the stair. I felt it looked like so attractive with the red and little black color. I never see this insect before. Therefore, I plan to snap it. If after I went back to take camera and it is still there then I will snap it. When I come out again, it is still there. I was so happy. Actually this insect is not big. It is just around 2cm length. However I did not whether it has posion or not. The reason is normally the insect that has sharp and nicer color sure will be poisonous.
