Pupae from El Salvador in the emerging window

Pupae from El Salvador in the emerging window.

After posting the weekly Fresh Sheet, we are often asked, “When will the butterflies emerge from their chrysalides to fly around our Tropical Butterfly House?” The answer can be highly variable.

Most of the butterflies listed below will be in flight within the week. In fact, our labels reflect a hint at their emergence rates. Look at this week’s pupae shipment from El Salvador in the emerging window. Notice that there are two different kinds of species labels: one type will be a solid purple color and the other one is white with a purple border. The solid purple label indicates pupae species that are “fast emergers.” These pupae typically emerge within a couple of days of being pinned. The white labels with a purple border denote pupae that take a bit longer to come out. We know these species are “slow emergers.” To further organize the pupae, we use different colors for each country of origin. In addition to purple for El Salvador, we use yellow for Malaysia, red for Suriname, and green for Costa Rica.

The next time you visit our Tropical Butterfly House stop by the emerging window and check out the fast and slow emerging species of butterflies. You may even get to see one emerge before your very eyes!

“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.
