Let’s discuss the genus Siproeta. Pacific Science Center is getting two of the three species from the genus, in our Costa Rica pupae shipment: S. stelenes (Malachite) and S. epaphus (Rusty-tipped Page). Their pupae are nearly identical – in fact, so similar that we have had farms mix them up and gotten a mixed emergence from very clearly labeled species. Luckily the adult butterflies are strikingly different in markings.

The Malachite is a brilliant green butterfly that, unfortunately for collectors, color fades with time. It may be a mimic of another species, Philathrea dido (Scarce Bamboo Page), a butterfly that is noxious to predators.

S. epaphus is either a black butterfly with a white band and rusty wing tips or a rust-colored butterfly with a band white band and a triangle of black near its body. Under the pigmented scales, the butterflies share very similar wing veins, which is a more reliable indicator of relatedness than color markings.

Both species of Siproeta are now flying in our Tropical Butterfly House. Visit us soon!

“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.
