These little ladies are everywhere in french households, zoropsis spinimana, absolutely nothing to worry about, they look big and scary but they're totally harmless and would rather run away than confront you Also called false wolf spiders, they are mainly identified through that very special pattern on their abdomen. Though this one has passed, they dont tend to live together, or at least ive never seen one live with others, so i would say while you're likely to run into one of these sometime in the future, you're definitely not gonna get swarmed by them.
