This is just a crazy idea that is probably not practical at all, but what if bibites can make certain sounds and hear them, it could somehow function sort of like their phermomones of sending signals, but might end up with bibites creating a language and hearing some *beep boop ba de do da ri ro re ra* sounds idk might be cute lol
Yeah and language would probably not be very useful for an organism that does not really work together in groups and survive more individually. Would probably make more sense if the bibites had to exchange resources, and had division of labour and skill and had more needs than just eat and reproduce.
