What is the life span of a butterfly?
The life span of a butterfly is dependent on the breed. They can live only a few days, anything up to a year, depending on the species.
The copper butterfly and small blue butterfly are generally thought to have the shortest life span and only live up to a maximum of a few days.
The longest life span is that of the migrating monarch butterfly, which can live up to 12 months.
The purposed average life span of an adult butterfly (not
caterpillar or pupa) is 20-40 days or 3-6 weeks..
It takes approximately 1-6 months and 5 weeks
Different species have different potential life spans. An average butterfly species has an adult life span of about 2 weeks or less. It is a common misconception that all butterflies live for only one day. However, no adult butterfly can live for more than a year. One particularly long-lived species (for a butterfly anyway), is the Monarch, which is why you tend to see more of them than other butterfly species.
Butterfly life span varies greatly. Opler and Krizek in Butterflies East of the Great Plains, state that the "expected life span" (which is usually much shorter than the "maximum life span" because of predators, weather, etc.) ranges from about 2 to 14 days after they emerge from the chrysalis. Maximum life span ranges from about 4 days (spring azure) to 10 to 11 months (mourning cloak). Females generally live longer than males.
