How long does it take for a Luna moth to become a butterfly?

2 to 5 weeks for moths but butter flies live up to 2 weeks the first week they grow up and get cared for and eat after being born in a cocoon and they second week they have kids and get eaten after the babies are laid in eggs and when they hatch they're catepillars and a catepillar changes how long it lives until it turns into a butterfly by how much they eat.
