Dryas iulia (Julia Longwing)

Dryas iulia (Julia Longwing)

In this week’s shipment, we have a nice crop of the Julia Longwing butterfly, one that seems to have gotten its common name from a typo. Sometimes we may see this butterfly listed by the Latin name Dryas julia, but actually its name is Dryas iulia. The “I” and “J” characters in Latin are often interchangeable, but not in this case. It may be because so many people read that wrong and mistook it for the word “Julia” that led to the common name, the Julia Longwing.

Dryas iulia is a lovely Heliconiidae butterfly, found in the southern United States in addition to the Central and South American countries we source our pupae from. These butterflies are well known for their behavior of puddling, drinking minerals from liquid, including sometimes from the eyes of other animals like turtles and crocodiles!

We don’t have turtles or crocodiles in our Tropical Butterfly House but we do have Julia Longwings. Come by soon and check them out!

“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.
