“I found this in my house. Never mind where in the world my house might be located–that’s superfluous information-and ignore the fact that this thing is 3mm long and I took the photo from a distance of 1.5m with a potato at 0300h with the lights off. What is it?”
Jesus Christ, you people. It’s 2016. If your phone camera sucks and you don’t want to upgrade, go to ebay and invest $25 in a used P&S with a fucking flash. OR…identify your own goddamned creepy-crawlies.
Probably a booklouse, but that judging only from the general shape and colour of your blurry blob, and estimating size by the texture of the wall.
Mangled remains of…an ant? Fuck, I don’t know. OP said it bit, but they always say, “this thing bit me” any time an insect or spider may potentially have come into some kind of contact with their skin.
