This week’s shipment of pupae from El Salvador contains three species that send Animal Care Staff to their butterfly identification books: Archeoprepona demophoon (Hubner’s Prepona), Archeoprepona demophon (One-spotted Prepona), and Prepona omphale (Blue Belly-Button).

These three species from the Nyphalidae family may look alike but are they? Zoom in! Look closely at their hind-wings. The pattern and size of ocelli (eyespots) on the ventral side of their wings are slightly different. Of course, there are other variations that are more difficult to detect and perhaps you can find other physical variations.

Look for Preponas on the fruit sways or roosting on plant leaves the next time you visit our Tropical Butterfly House. They are the butterflies with pink proboscises.

“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.
