The number of days that it takes to be a butterfly depends upon the particular lepidopteran, with a typical span of 4 to 20 days in the last stage as the beloved flying pollinator even though adulthood may last for:
- 2 to 10 weeks for great spangled fritillaries;
- 2 to 4 weeks for gulf fritillaries;
- 1 to 3 months for milkweeds;
- 1 to 5 months for zebra longwings.
Adulthood will be preceded by egg, larval and pupal stages that add anywhere from 3 to 14 weeks.
The total days will tend to range from 25 to 118 dayseven though life cycles may range longer for such species as:
- great spangled fritillaries, with 59 to 137-day lifespans;
- zebra longwings, with 53 to 189+-day lifespans.
