Greta oto (Glasswing)

You may remember being told that rubbing butterfly wings will brush their scales off. But Greta oto (Glasswing) butterflies don’t have scales on their transparent wings. That doesn’t mean it’s ok to touch them. They are very fragile and their little wings are easily torn. Despite this they can fly up to 12 miles per day and go on long migration flights.

Many butterflies use their bright colors to attract a mate but obviously this would not work for a species with transparent wings. Instead, the Greta oto males congregate on the forest floor where they emit pheromones and engage in competitive display to attract females. Female Glasswings approach the group of males and select a mate based on his display behavior. Mate selection by females from a group of displaying males is called lekking.

“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.
