Here comes the sunshine, or as close as we can get it by receiving our pupae from somewhere warm.

Included in this week’s shipment are small numbers of two sulfur butterflies: Phoebis sennae, the Cloudless Sulfur and Anteos clorinde, the White Angled Sulfur or Ghost Sulfur. We rarely get the ghost sulfur, which is a lovely treat to see.

Sulfur butterflies are typically bright yellow, with or without orange or white markings, hence the name sulfur. Anteos clorinde is likely called the Ghost Sulfur due to its pale green color, the opposite of the usually brilliant shades of others in its family. Sulfur butterflies are often migratory and flutter around in colorful yellow clouds, crossing water and roads on their way to new habitats.

In the butterfly house we take special care to find appropriate food for them. We place a sugar feeder in the emerging window to help them eat shortly after emerging for a quick boost of energy. Releasing them onto the powder puff flowers helps them get the sustenance they require as they have a strong preference for red blossoms. Although they are small butterflies, they have a long proboscis that can get the nectar from between the fluffy petals.

Come visit our Tropical Butterfly House soon and make sure to find the Ghost Sulfur and see it for yourself!

“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.
