Vindula dejone (The Cruiser), male on the left and female on the right, look like very different species.

Observe Vindula dejone (The Cruiser). This butterfly has very striking sexual dimorphism. It would be easy to think that the orange male and the larger, brown and white female were two different species. Their behavior is different too. Male Cruisers are one of the most common butterflies found sunbathing and puddling on the floors, drinking water to absorb its minerals. When they puddle these butterflies are nearly oblivious to their surroundings. You have to look out not to step on them; they won’t fly away. The females are much less likely to rest on the ground. Instead they hang from plants high in our Tropical Butterfly House. Both sexes are among the fastest fliers in the exhibit. Their swift, directed flight can be startling when so many other butterflies are gentle flutterers. But fear not – no butterfly has any body part that it can use to hurt us.

“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.
