First, the little caterpillars had to hatch and go to work eating our Passion Flower vine. That is a lot of work!
Next, they had to form their chrysalises and start the process of becoming butterflies. Again, more hard work.
Finally, they erupt from their chrysalises as adults. They are free to enjoy some time at the end of summer drinking up all the nectar they can get before they head to Mexico, or even as far as South America, for the winter.
