Did You Know
- Tim Wong an aquatic biologist at the California Academy of Sciences constructed a home for butterflies in the backyard of his dwelling place where the California Pipevine Swallowtail was found alongside other species.
- Their numbers had declined drastically and revival to some extent was made in 2017.
- The California pipevine plant from which they derive their name contains aristolochic acid, a toxic substance, which is why the juvenile, as well as adult species, have toxin content in their tissues.
