Male Atlas Moths (Attacus atlas) in the emerging window of our Tropical Butterfly House.

The first pupae shipment of 2018 comes to us all the way from Malaysia. We’re starting off the year with a bunch of fan favorites, the Atlas Moths (Attacus atlas). Atlas Moths reach adulthood without any mouthparts, so they have one of the shortest adult lifespans of all the species that come into our Tropical Butterfly House. They are only adults for about a week before they die of dehydration. But remember, these Lepidoptera were actually all born back in 2017. After an Atlas Moth hatches from its egg, the caterpillar develops for about 35-45 days before it pupates. So the majority of these animals’ lifespan was actually last year. Come by and enjoy them while you can!

“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.
