Battus polydamas (Gold Rim Swallowtail) caterpillars and emerging butterfly

Battus polydamas (Gold Rim Swallowtail) caterpillars and emerging butterfly

This week we are highlighting Battus polydamus, the Gold Rim Swallowtail. This species is one of the pipevine swallowtails that eat only Aristolochia, a plant that is toxic to most other animals but is a feeding attractant to the many swallowtail species that eat it.

This species is a particular favorite because upon emergence, the butterfly nearly fills its empty pupa with a red, watery meconium that also falls to the ground below. It is one of the brightest and most copious meconium of any butterfly we get!

Are you curious? Listen to this recent podcast to hear how Animal Caretaker Gabriella Boyer has found beauty in butterflies’ meconium and has actually created works of art. Her creativity and joy have taught all of us that there is wonder to be found wherever you look.

Visit us soon and see this phenomenon for yourself.

Adopt a Butterfly

Love the Tropical Butterfly House? Spread that love by adopting one of our beautiful winged creatures! Starting at just $50, your adoption will help care for the butterflies in the Tropical Butterfly House, and support of the hands-on science programming offered at Pacific Science Center. And, you’ll receive some exclusive benefits for your generosity.

“Fresh Sheet” is our weekly shipment report of pupae on display in the emerging window. Visit Pacific Science Center’s Tropical Butterfly House and meet our newest residents.These butterflies typically arrive as pupae on the Thursday or Friday before the Fresh Sheet is published. Some of these butterflies will start emerging the day they arrive or the next day, but other species may take a full week before they reach adulthood. After emerging, they may live for a week or even a few months! While we love sharing a variety of species with our guests, we cannot guarantee that any specific species will be flying on the day that you visit Pacific Science Center.If you are interested in photographing a specific butterfly and would like to be updated about when it is flying in the Tropical Butterfly House, please email with details and your contact information.
