March 14 is Learn About Butterflies Day! There's no better place to do this than the Insect Zoo, located in the Exploration Zone of the Zoo. Inside, you'll find caterpillars going through the complex biological process of metamorphosis, getting ready to spread their wings later this spring. Take a quick tour of the Insect Zoo in this video and don't forget about our Insect Keeper Talks on Saturdays at 2:30 pm. #sfzoo | San Francisco Zoo
