stwy on "ID please (possible cast skin and bug)"

(related to http://bedbugger.com/forum/topic/can-bites-vary )

I found these by sticking duct tape into gaps in a piece of furniture, I caught the bug by the back, so it did get a little squashed when I transferred it to another piece of tape and possibly lost the top layer of skin (or whatever it has) on its back

Any feedback would be incredibly helpful!

Thanks
