Have you ever wondered why butterflies are frequently seen down on the ground in a patch of moisture or a puddle? This behavior is called “puddling” and is primarily an activity of male butterflies. The salts and minerals in puddles are an additional supplement to a butterfly’s diet of nectar. These nutrients are necessary for butterfly reproduction.

The next time you visit our Tropical Butterfly House, take time to observe butterflies puddling on the ground, but please – be careful where you step!

“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.
