They Touch Butterflies, Don’t They?


As most of our readers know by now, “Flight of the Butterflies” is playing at the Boeing IMAX Theater in 3-D to the delight of audiences of all ages. The movie tells the story of Dr. Fred Urquhart’s 40-year quest to uncover the Monarchs’ migration secrets.

SPOILER ALERT: Read no further if you haven’t seen the film and would like to discover the story on your own. But be sure to come back and read this article after seeing the film!


In the course of the movie, there are several scenes showing people actually touching butterflies – a definite no-no in our Tropical Butterfly House. So what’s the difference?

Like all Animal Care Staff, the citizen scientists in the film were trained on how to handle these delicate creatures without hurting them or damaging their wings. Butterfly wing tagging is performed with the least amount of handling necessary and the butterflies don’t appear to be encumbered by the tags. Currently there is no better way to track a butterfly’s migratory patterns, although the tags have gotten smaller. Citizen scientists are essential to information gathering. By tagging of a small percentage of the Monarch population, scientists learn a great deal about this species. This data helps us to better understand butterflies and their migration patterns.


In our Tropical Butterfly House, we have no good reason to touch butterflies with our fingers. Even Animal Care Staff carefully gather butterflies from the emerging window with forceps and release them as gently as possible. When forceps are use, Staff is trained to gather all four wings firmly but efficiently to cause as little stress to the butterfly as possible.


We have so much to learn from these amazing insects, it is only fair that we treat them with respect while they are in our care.

Make Way for the Monarchs!


In honor of the upcoming IMAX film “Flight of the Butterflies”, additional monarch butterflies (Danaus plexippus) will be displayed in the Tropical Butterfly House.


This has proven somewhat challenging. Monarchs are bred seasonally during the spring and summer months, and supplies are limited right now. This makes sense. In the wild, they would be in reproductive diapause all winter long. They would be conserving all their energy to survive the winter, and their reproductive organs would shut down until spring. Much as we might admire their adaptation, it has made finding them harder!

To hedge against possible late season pupa failure, we have purchased both butterfly chrysalis and adult butterflies for the opening week of the film. Did you know that butterfly vendors store adult butterflies in the fridge, sometimes for weeks or months at a time? It simulates the natural overwintering behavior of the butterflies and they are none the worse for wear when they get back up to warmer temperature. It’s not as simple as just sticking them in the vegetable drawer though. Temperature and humidity must be carefully monitored to stay within the safe range, or the butterflies may not recover.

Here is a short video of our Monarch release.



Monarch butterflies are attractive at every stage of development. If you've never noticed it, take a look at the giant chrysalis hanging by the emergency exit door of the Ackerley Family Gallery, near the orb of the Boeing Imax theater. Admire it, and then see the real thing in the emerging window. If you are lucky, you may see the pupae shortly before the adult emerges. At that point the wings have taken on adult color and are visible through the walls of the pupa.


One more note. Monarch butterflies are not typically a big part of indoor, tropical butterfly exhibits. They tend to be less zippy than some other species. However, they should flock together in groups, and they should all seek the same types of flowers and locations. It will be interesting to see how they use our space. We’d love to hear your observations!
