An adult butterfly will eventually emerge from the chrysalis where it will wait a few hours for its wings to fill with blood and dry, before flying for the first time. Butterflies can live in the adult stage from anywhere between a week and a year, depending on the species. Butterflies have four wings. Butterflies often have brightly coloured wings with unique patterns made up of tiny scales. Most butterflies feed on nectar from flowers. Butterflies have taste receptors on their feet.
