You can see the white pupa casing on the back of this oriental rug. This site had clothes moths, and of 8 oriental rugs, 6 had readily visible evidence of activity. These photos are all from the rear of the rugs or the floors beneath them. The next photo is the hardwood floor and the grainy frass left by the larval stage feeding on the rug.
White line highlights the line the larval stage ate from the rug.
