Mechanitis polymnia (Polymnia Tigerwing)

Mechanitis polymnia (Polymnia Tigerwing)

This week’s pupae shipment includes the species Mechanitis polymnia (Polymnia Tigerwing). This is one of the smallest members of the tigerwing butterflies. Their beautiful bright gold chrysalis is fascinating. When the butterflies emerge as adults, people are surprised to see that none of that gold is represented in the adult form. Mechanitis polymnia look like smaller versions of the Tithorea harmonia (Harmonia Tigerwing), both in chrysalis and adult form. But remember, smaller butterflies are never going to grow into bigger butterflies. A butterfly is full grown as soon as its wings are dry.

“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.
