Morpho polyphemus (White Morpho)

Morpho polyphemus (White Morpho)

This week’s pupae are from El Salvador, and include a nice mixture of species.

Some of the behaviors of the White Morpho, Morpho polyphemus, are worth highlighting. This butterfly is described as a ‘path following’ species. It flies low in the canopy of rainforests and navigates by following trails, ravines, forest edges and other landmarks. In the butterfly house you can often see them flying at about 1/3 of the way up the exhibit, on paths that only they seem to know about.

This is a species that in the wild would include tree sap in its diet. The White Morpho is easily disturbed and is sometimes chased by our more assertive species. However it prefers more forested areas that most of our butterflies.

Come visit our Tropical Butterfly House this weekend and trace the path of the White Morpho.

“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.
