Different butterfly species have different adult potential life spans. By marking butterflies then recapturing or sighting them later scientists gain information on how long butterflies can live. An average butterfly species has an adult life span of 2 weeks or less. For example one butterfly studied in Costa Rica had a life expectancy of about 2 days, and live 10 days at the most. No adult butterfly can live more than a year
