San Francisco is a beautiful city, full of sights, history, and culture. But like any city, it’sbeen built pretty much exclusively for its human population despite the fact that there are many, many other creatures that call cities home.
One animal that called San Francisco its home was the California pipevine swallowtail, a beautiful butterfly with iridescent sapphire wings. Butterfly enthusiasts consider it one of the most stunning butterflies in North America.
But as the city grew and grew, the butterflies’ habitat shrank, causing the populations to dwindle. Today, there are drastically fewer pipevine swallowtails than there were in years past.
And that just wasn’t acceptable to Tim Wong.
Wong is an aquatic biologist working at the California Academy of Sciences, but his love for animals extends out of the water, too.
As a child, he was always fascinated with butterflies, and started raising them at home. And even if you’re not a butterfly fan, watching them transform from caterpillar to winged insect is pretty magical.
In 2012, Wong decided to try and boost the population of the pipevine swallowtail. After learning of their dwindling numbers, he made it his personal mission to bring them back to his city.
