The Flight of Monarch Butterfly 64365

Somewhere in L.A. a monarch egg hatched and out popped a tiny girl caterpillar. That caterpillar ate, and ate, and ate. She ate milkweed, the only plant she could, until she molted her skin. All told, she molted four times until she was a big, fat, stripy caterpillar with black tentacles. She made one last molt and formed a bright green chrysalis with shining golden spots. Two weeks later she emerged from that chrysalis as an adult, and then she flew. On November 17, 2014 she was spotted in the Museum’s Nature Gardens. She was caught in a net, and gently removed by skilled hands. A small, circular, paper sticker was affixed to her hind wing with the numbers 64365 printed on it. She was released and flew off into the distance. We knew there was a good chance that we’d never see her again.

It is that time of year again! Sunday is the opening of our Butterfly Pavilion, and although we still have hundreds of free-flying butterflies there's a lot that has changed out there. We have replanted the entire space, adding many more nectar and host plants for adults and caterpillars. We have also added new food sources for some of the adult butterflies that aren't quite so partial to sipping nectar!

The Mourning Cloak butterfly, Nymphalis antiopa, is one of the California native butterflies we put in our pavilion. Although these butterflies are not common to our area, they can be found in areas where their host plants thrive. Caterpillars of this species feed on various willow (Salix species), cottonwood (Populus species), and ornamental elms (Ulnus species). Unlike many of the other species of butterflies in our pavilion, the Mourning Cloak butterfly prefers to feed on rotting fruit  rather than plant nectar. In an effort to appeal to...
