A cocoon

Look at this! It's a cocoon! I saw it last last week, in the toilet. I climbed on a stool and I saw something moving in it, should be a caterpillar, moving its head left and right to encase itself.

2weeks has passed. Nothing came out of it. I wonder how long does it takes for it to emerge as either butterfly or moth. I suspect it's a moth.

When you look closely, it's very strange. It's not like the usual cocoon which is a hardcase. This looks like a lot of very short hair gathered and stuck together...
I hope I get to see what comes out of it~!

20/7/09 Note : We never saw anything came out of it. One day I just saw a line of stain (liquid flowed down). There was another of this "cocoon" near the toilet window. It too had that stain. I guess the bugs in it was gone. The cocoon itself didn't look much different. Too bad, didn't see what came out of it.
