They are an abnormally large group of hoarding bugs that are usually carrying high value items. Usually the leader is holding an apparatus. They will not attack you if: you give them all your items There is a chance they will attack you if: you run away without giving them items, they scam you, (attacking you right after you trade) They WILL attack you if: you attack them, steal their items, or die. (They will collect your dead corpse like a piece of scrap)
