Heraclides thoas (Thoas Swallowtail)

Heraclides thoas (Thoas Swallowtail)

This week’s pupae shipment contains one of the more confusing butterflies that we work with, the Heraclides thoas. This butterfly is a reminder that even scientific names don’t eliminate all the confusion of working with a lot of different species. Depending on whom you ask, the Heraclides genus is sometimes lumped in with Papilio and sometimes a genus of its own. So if you ever see a butterfly commonly known as a Thoas Swallowtail, referred to as a Papilio thoas, you’re looking at the same exact butterfly as a Heraclides thoas.

“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.
