As you may recall, I purchased some Painted Lady caterpillars a while back as a diversion during the state “safer at home” orders during the pandemic. The caterpillars arrived along with their “muck in a cup” (or pre-made food).
After about ten to twelve days, the caterpillars crawled to the top of the cup in which they arrived and started to form the tell-tale sign that they were about to form pupae. The tell-tale sign that signals the beginning of this stage is seen when the caterpillars begin to look like the letter J, as they prepare to bundle up to make a case which is attached to the cup lid by a silk pad they have fabricated. After about twenty-four hours of hanging upside down, the caterpillar skin splits off and exposes a case or pupa.
Seven to ten days later, the painted lady breaks free from its pupa and metamorphisis has been completed. During this stage, the adult structures are formed, and finally the pupa has now turned into a butterfly that needs to dry his wings before he can fly.
Wings dry and harden after about twenty-four hours, and the butterfly continues his life for about two weeks during which the butterfly can travel up to one hundred miles a day at thirty miles per hour. The butterflies can mate around five to seven days after emerging from the cocoon, and the female can lay as many as approximately five hundred eggs in their short life time. Eggs are singly laid on a host plant, such as thistle, mallows, hollyhock, legumes, and others. Once the butterfly reaches the adult stage, their diet includes many nectar plants, such as blazing star, cosmos, New England aster, Joe-pye weed, Mexican sunflower, purple coneflower, and zinnias. They will visit other nectar plants, though, including red clover and milkweed, too.
In our home, when we woke up one morning to find that the first one of our pupae had hatched into a butterfly, there was a great deal of red exudate on the side of the net cage. This exudate is not blood, as many people think, but is meconium, which is waste products of their metamorphic activity.
Shortly after, a second butterfly emerged before we knew it, about a half hour later. We decided to watch the remaining pupae and actually had the good fortune of actually seeing a butterfly emerge from its pupa stage. It was a magic moment, watching life literally unfold before our eyes.
After giving the painted ladies some orange slices and sugar water on a cotton ball on dish in their cage, we decided to let them go free. It was yet another magic moment for us, as my daughter reached inside their cage, and the each butterfly crawled onto her hand in order to be released.

If you are interested in raising butterflies, I would recommend you order a kit with pre-mixed painted lady food to start (“the muck in a cup”). Now that we’ve gotten the butterfly “bug”, we plan to raise butterflies from eggs to caterpillars, then caterpillars to pupae, then pupae to adult butterflies. Each type of butterfly needs a certain host plant to lay eggs upon, but there are often many nectar plants that they will eat from as adults.
Three valuable sources of information and supplies can be found at:
We have been busy gathering a few host plants and many nectar plants for containers around our yard and likely will try malachite butterfly eggs next.
