Butterflies' lifespans vary widely depending on the species and environmental factors.

• Most adult butterflies live about 2 to 4 weeks, with many species surviving only a week or two as adults

• Some species, such as the painted lady, typically live around 14 to 28 days as adults, but their total life cycle from egg to adult can last up to a year

• Monarch butterflies usually live 2 to 6 weeks, but the generation that migrates and overwinters can live up to 7 to 9 months

• Certain species like the mourning cloak and red admiral can live several months, especially if they hibernate through winter

• Small species may live only a few days, while some butterflies in colder climates may have life cycles extending up to a year or more due to overwintering stages

In summary, while the average adult butterfly lives a few weeks, some species can live several months, especially those that migrate or hibernate, and the entire life cycle from egg to adult can span from weeks to about a year depending on the species
