Caligo memnon (Giant Owl Butterfly) at rest.

Caligo memnon (Giant Owl Butterfly) at rest.

This week, we are getting 80 Caligo Memnon (Giant Owl Butterfly) from Suriname. These butterflies got their name for the big yellow marking, like an owl’s eye, on their hindwing. You would think that 80 enormous butterflies with big yellow eye-markings would dominate the house, but they are actually pretty subtle.

Owl butterflies are crepuscular (active at dawn and dusk) so mid-day you have to look for them. Likely you will find them resting on the trunks of trees. Once you start noticing them you will see more and more. And if you happen to visit our Tropical Butterfly House late in the day when they get active, the whole space changes! It is when the brightly colored butterflies settle down for the day that the big Owl Butterflies get busy.

Come visit Pacific Science Center’s Tropical Butterfly House soon and zoom in on these and other big, beautiful butterflies.

“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.
