Fresh Sheet – October 13, 2018

If you see a Monarch-looking butterfly with blue wings instead of orange, you may be looking at Danaus agleoides (Blue Glassy Tiger).

The pupae this week are coming to us from Malaysia. We often end up with little reminders about the world where our butterflies are coming from and this week is one of those. Malaysia is experiencing monsoon levels of rain that are wreaking havoc on some of the butterfly farm production. As a result, we have a smaller shipment this week and some often-represented species are not present.

On the plus side, we do have a species that we haven’t seen in our Tropical Butterfly House before: Danaus agleoides, or Blue Glassy Tiger. It is a good example of the way things in the same genus can look so similar. Look for a butterfly with the same sort of wing pattern you would find on a Monarch butterfly (Danaus plexxipus). If you replace the orange color with a light blue, you’re looking at a fairly good match to this new butterfly house resident. Try to find one on your next visit!

“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.
