Can anyone ID this? I found it caught behind a wall light switch cover. It freaked me out to hear scraping noises that seemed to be in the walls, as I was reading a book on my couch on the wee hours, not understanding where the sound was coming from as everytime I went near, it stopped, but perserverance paid off and soon I saw a pair of antenna stickong out. I dont know how it got there and couldnt get out and am really hoping its an eacaped nymph of one of my colonies and not a sign of an American roach infestation. For reference, I am near Chicago.
