reserving the right to change my answer on this but honestly it's probably also spiders. they're cool as hell and they generally respect your personal space unlike winged bastards. and they eat stinkbugs. i had one of those big garden orb weavers on my window a few years ago and any time a stinkbug got into the house I'd flick it into her web and watch her go apeshit wrapping it up. very cool animal
plus crabs are just water-type spiders. i will not be accepting criticism on this
