Greetings from Butterflies & Blooms! I have great news for my fellow Lepidoptera enthusiasts! We have a very interesting new species in the exhibition. Meet Caligo atreus, also known as the yellow-edged owl, or our favorite: the magnificent owl.
This blue beauty is in the genus known as the owl butterflies (Caligo). They’re called owl butterflies because the markings on the undersides of their wings have large black eyespots that resemble the eyes of an owl. (You will typically see the eyespots when the butterflies’ wings are closed.) This is thought to help them ward off predators. Caligo translates to “darkness,” which corresponds to the fact that they prefer to fly in the early morning before their predators are out and about. They are native to the tropical forests of Central and South America, and are among the world’s largest butterflies!
We also have a few other species in the owl genus, including the giant owl and the forest owl. However, the magnificent owl is aptly named, as it is much more colorful than its peers—its dorsal side has deep blue striping on the top part of the wing and bright yellow on the bottom half of the wing. During most of the day, you can find them hanging out on the fruit trays or resting in the shade, but if you come early, you’ll have a good chance of catching these graceful giants dancing around the exhibition, showing off their beautiful coloration.
July 29, exactly one week ago, was definitely the most exciting day for me at the Butterflies & Blooms exhibit this year!
On July 3, we received what looked like “naked” pupae. These were the pupae of the bull’s eye silk moth, or African emperor moth (Gonimbrasia zambesina). Aside from a very slight wiggling the first day or two, the pupae just sat there in their box. Then, on Wednesday morning, I checked on them and noticed one of the pupae looked like it was broken open like an empty eggshell…but I couldn’t find a moth or anything else—until I looked up and saw it hanging in the top corner of the display! It was fabulous. I literally ran out to the volunteers to tell them the good news! (They ask, “Are there any new moths?” on a daily basis, and I usually have to say no.) I brought it out and placed it in the safest place I could think of, while still being easily visible to guests. I personally didn’t take a photo, but all the volunteers did—so that’s what you see here. It’s been a dramatic week!
As far as the native butterflies and moths in our exhibition right now, we received 30 white peacocks, 12 buckeyes, and 8 gulf frits. I’ve never seen a gulf frit, so I’m looking forward to those pupae hatching. They came in on July 28, so I expect them to emerge any time now. (The smaller butterflies seem to emerge the fastest.)
