Bug in the house

"Last night I saw this bug on my ceiling lamp, I got tempted to capture this, it took me an hour to capture this, though the lamp shade was on a height, I tried this from my spring bed, then I put duvet to make some height, it was very shaky and I was standing on edge of the bed. Even once I got unbalanced and managed to save my camera to fall.
This bug really had bugged me, he was not stand still and kept walking on rim of the lamp. Really that was the BUG."
