Fresh Sheet – July 20, 2019
Among the eleven butterfly species we are receiving this week, there are two that closely resemble each other. They are Danaus vulgaris (Blue Glassy Tiger) and Tirumala septentrionis (Dark Blue Tiger). Both are in the Daniadae or milkweed butterfly subfamily of Nymphalidae, the brush-footed butterflies and both can be found in Southeast Asia.
The easiest way to tell them apart may be by their wingspan size. The Danaus vulgaris has a wingspan of 70-80 mm, whereas Tirumala septentrionis has a wingspan between 80-115 mm.
Be curious! Look for these two species in our Tropical Butterfly House and 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 Butterflies@pacsci.org with details and your contact information.
