Maybe it had something to do with this:
|Possibly the world's oldest Pipevine Swallowtail. :D|
I spied the 'old dude' above just chilling on some greenery. He wasn't moving, so I thought he might have been dead. Nope. I small gust of wind came along and, while he didn't lose his perch, his wings fluttered slightly.
Although this butterfly is found in many spots around No. America, the SF population is a finicky eater and, by about five years ago, its numbers had dwindled to very few. A local scientist by the name of Tim Wong set about to turn the tide on these lovely butterflies. Armed with a bunch of California pipevine plant obtained from the SF Botanical Garden and a bunch of caterpillars, Wong was able to create a back yard environment in which this butterfly could thrive. Indeed, the abundance of caterpillars I saw at the Botanical Gardens is due to Tim Wong's conservation efforts. To read a bit about Mr. Wong's butterfly project, go here.
