Butterflies often appear delicate.
Butterflies always feed on nector, water, sometimes rotten fruit.
They take in far more liquid than most insects. This means their body must find a quick and efficient way to release excess fluid.
Unlike mammals, butterflies pee by releasing tiny droplets of clear or slightly cloudy from their abdomen.
These droplets are usually invisible.
Digestive system of butterflies extracts nutrients quickly and expels the leftover fluid.
This helps them to stay light and ready for flight.
Butterfly pee dries up fast,, has no noticeable smell and often goes unnoticed in nature.
