Troides helena (Common Birdwing) eclosing.

Troides helena (Common Birdwing) eclosing.

In this week’s pupae shipment from Malaysia we have a small number of the big Troides helena (Common Birdwing), a remarkable member of the Swallowtail family (Papilionidae). At one time, Birdwing butterflies were collected to near-extinction. But now thanks to conservation and sustainable commercial farming, Birdwing butterflies are making a comeback in the wild and are available for us to enjoy in our Tropical Butterfly House.

Look for them nectaring up high on colorful flowers. If you visit us soon, you may even see this butterfly eclosing from a pupa in the emerging window.

“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.
