Help identifying a bug?

My room is in the basement, I usually never see any bugs around but I was laying in bed and just noticed a small black bug (bigger than a flea smaller than a ladybug) crawl in front of my iPod light. It had antennas, no wings, and was startled when I moved me iPod and started moving quicky so I smushed it easily will no body left (carcus/exoskeleton) I have also noticed 3 different large spiders around just this weekcone being a wolf spider.. I believe I saw this bug on my shirt one day as well
