Mosliquo collect bacteria in water as food, and in place, suck in water. To excrete this water without throwing away the nutrients it needs from the bacteria, Mosliquo has a filter organ in its abdomen, which can be used as a natural water gun. Its water should never be consumed by any humans or other Pokémon, as it can cause illness.
Mosliquo, long escaping their water habitat, still fly around swamps to feed on growing bacteria, and to lay eggs.
Mosliquo sips clean water from swamps and rivers using their long mouthparts. Some Mosliquo also consumes fruits; they ferment inside its abodmen and become fine wine.
