lol, looks like the centipede from James and the Giant Peach animated movie.
I think the most dangerous insect we have around here is the Brown Recluse (Fiddleback) spider. Depending on a person's resistance, a bite can cause a simple puffed/red/itchy area around the bite (this is what happens to me) to a severe reaction where the tissue around the wound basically rots away. Very nasty. Generally not aggressive, but they do bite when cornered. And they like to hide in dark secluded areas (hence the name) like shoes, under bedsheets, clothing etc - pretty much anywhere an unsuspecting human would shove an unprotected body part.
I would imagine that creepy crawly was in your laptop because it was nice and warm. It probably got
too warm with an active CPU to be comfortable so it decided to vacate. That'll teach you to use your laptop.
