Saving a Rare, Ocean-Blue Butterfly, One Little Beauty at a Time…

Ocean biologist and California resident, Tim Wong is single-handedly helping to save a beautiful species of butterfly once native to San Francisco.

The California pipevine butterfly is named for the pipevine plant on which it lays its tiny orange eggs (sometimes as few as 5 of them). It’s also the only plant that it’s striking Halloween-colored caterpillars will eat.

Once common in the area, human development has caused these butterflies to dwindle in number.

Tim grew up raising butterflies. And now, he is raising California pipevine butterflies, in a homemade enclosure on his property.

He learned they were rare; so, he found clippings of the pipevine plant at the local Botanic Gardens, built the enclosure, and began to cultivate the plant.

Tim then collected a handful of “later-growth-stage” California pipevine caterpillars from neighbors’ yards (with their permission), and nurtured them through the pupa stage until they became adult butterflies.

And the rest, as they say, is “history”. You can read Tim’s story in detail at, here:
