Troides helena (Common Birdwing)

Troides helena (Common Birdwing)

Below is the list of pupae coming to us this week from Malaysia. Included in that number is the Troides helena, a butterfly that is seriously undersold by its common name, the “Common Birdwing.”

While there are many subspecies of Birdwings found throughout Southeast Asia and Australia, it is far from common looking. “Birdwing” refers to the large size of this butterfly as females can have a wingspan up to 18cm! They are strikingly black with large yellow patches on their hindwings. Even though this shipment only contains ten pupae, your likelihood of spotting this gorgeous giant in our butterfly house is high.

Come visit our Tropical Butterfly House soon and zoom in on this spectacular swallowtail. You’ll be amazed!

“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.
