No doubt many of them did.
The award-winning book, published in 1969, traces the complete metamorphosis of a butterfly, from an egg to a larva (caterpillar) to a pupa (chrsyalis) to an adult.
If you've ever seen a Gulf Fritillary caterpillar chowing down on the leaves of a passion flower vine, you've seen The Very Hungry Caterpillar in action.
We planted a passion flower vine two months ago in our yard. The plant hasn't yet bloomed, but the Gulf Fritillary (Agraulis vanilla) found it. Thankfully! We planted it for them.
Within what seemed like a matter of days, the passion flower vine (the host plant of the Gulf Frits), went from no caterpillars--zero, zilch, nada--to five.
We've seen the showy orange-reddish butterflies fluttering around the plant looking for places to lay their eggs, but haven't seen them actually do it.
But the evidence is there!
"As a spiny orange-and-black caterpillar, it feeds only on passion flower leaves, eating many but not all species of the genus Passiflora," says butterfly expert Art Shapiro, distinguished professor of evolution and ecology at UC Davis. "There are no native members of this genus in the state of California, but several are widely cultivated in gardens."
The butterfly, he says, can breed where there is a "critical mass" of these plants in a town or neighborhood.
Let there be a critical mass!

Ah, the Gulf Fritillary...
We spotted this orange-reddish butterfly nectaring lantana last Saturday near downtown Vacaville. In fact, the patch of lantana (family Verbenaceae) drew assorted butterflies, including buckeyes, alfalfa, monarchs, and painted ladies. A few honey bees and native bees tried to get their share.
Lantana and Gulf Frits. These multi-colored blossoms and the multi-colored butterfly, both found in the tropics and subtropics, are a study in brilliance.
On his website, butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis, says the Gulf Frit (Agraulis vanillae) was introduced into southern California in the 19th century, and was first recorded in the Bay Area before 1908. Once prevalent in the Sacramento area in the 1960s, it "seems to have died out by the early 1970s," he said.
Then in 2009, it began making a comeback in the Sacramento area.
Now it appears to be thriving in some areas, at least where its adopted host plant, the passion flower vine (genus Passiflora), grows. If you have a passion flower vine in your yard, you may very well see the spiny orange-and-black caterpillars feeding on the leaves. And if you have lantana or Mexican sunflower (Tithonia) in your yard, don't be surprised if a few adults drop by for a sip of nectar.
No wonder that commercial companies mass-rear these exotic-looking butterflies for release at weddings, garden parties and other social events.
