100 Years – 100 Objects: Queen Alexandra’s Birdwing

January 13, 2009

The Houston Museum of Natural Science was founded in 1909 – meaning that the curators of the Houston Museum of Natural Science have been collecting and preserving natural and cultural treasures for a hundred years now. For this yearlong series, our current curators have chosen one hundred exceptional objects from the Museum’s immense storehouse of specimens and artifacts—one for each year of our history. Check back here frequently to learn more about this diverse selection of behind-the-scenes curiosities—we will post the image and description of a new object every few days.

This description is from Nancy, the museum’s director of the Cockrell Butterfly Center and curator of entomology. She’s chosen a selection of objects that represent the rarest and most interesting insects in the Museum’s collections, that we’ll be sharing here – and on hmns.org – throughout the year.

Female Queen Alexandra’s Birdwings are the largest butterflies in the world, reaching wingspans of more than 14 inches. Males are smaller, but more beautifully colored than females:  they have iridescent green and blue markings and a bright yellow abdomen, while females have brown wings with white markings and a cream-colored abdomen. Birdwings are members of the swallowtail family (Papilionidae).

The Queen Alexandra’s Birdwing is highly endangered, and along with several other birdwing butterfly species, was placed on the Appendix I CITES list in 1977 (collecting or trading wild-caught CITES I species is prohibited by international agreement).  Our specimens were acquired before they were officially protected.  Today, the museum would be unable to obtain this or several of the other birdwing species we have in our insect collection.

Learn more about butterflies and their relatives in a visit to the new Brown Hall of Entomology, a part of the Cockrell Butterfly Center– a living, walk-through rainforest at the Houston Museum of Natural Science.

You can see larger and more detailed images of this rare specimen – as well as the others we’ve posted so far this year – in the photo gallery on hmns.org.

    Why are all the exhibits on the list all art exhibits? Why aren’t there any science exhibits? That list cannot be a good one! The Terracotta soldier is an art-based one because it is mainly being exhibited in art museums like British Museum, Bowers Museum, and High Museum.

    I can’t say why the editors at Time chose to focus on art exhibits. But I think the Terra Cotta Warriors are art objects that have scientific and historical value. So at least a little science got on the list.
