We have strippers.
Not anything to do with that thriving business known as "The Strip Club" in Las Vegas.
The strippers we have are Gulf Fritillary caterpillars, which can skeletonize their host plant, the passionflower vine (Passiflora) faster than you can sing "Supercalifragilisticexpialidocious" (Mary Poppins movie) forward and backwards ("Dociousaliexpilisticfragicalirupes").
Seems as if one minute the plant is bursting with shoots, tendrils, leaves, flowers and stems, and the next minute, nothing but lots of little larvae.
But we like it that way. The tiny reddish orange caterpillars will turn into glorious reddish orange butterflies, Agraulis vanillae. It's a tropical and subtropical butterfly with a range that extends from the southern United States all the way to central Argentina, according to butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, who has monitored scores of butterfly species in the Central Valley for more than four decades. (See his website.)
You probably remember the story. Back in September of 2009, the professor excitedly announced the re-appearance of the Gulf Fritillary butterfly in the Sacramento metropolitan area after a four-decade absence, and in the Davis area after a 30-year absence.
The showy butterfly colonized both south Sacramento and the Winding Way/Auburn Boulevard area in the 1960s but by 1971 "apparently became extinct or nearly so," recalled Shapiro, who moved to the Davis area in 1971.
True, some gardeners don't like to see their plants reduced to a skeleton, something they think should appear only on Halloween night.
But to us--and many others--passionflower vines are just food for the caterpillars. To be a butterfly, you first must be a caterpillar.

It's sort of like watching the grass grow, or the paint dry, but there's much more drama.
These, as children's book author Eric Carle writes in the children's book, "The Very Hungry Caterpillars," are very hungry caterpillars.
They're famished. They're ravenous. They could eat a horse (except they don't eat horses). And that's a good thing, as Martha Stewart would say.
If they're allowed to, these caterpillars will decimate the leaves, spin cocoons and eventually turn into spectacular reddish-orange butterflies (Agraulis vanillae).
So, you're sitting there watching the caterpillars eat. And out of the shadows, something else appears.
You think you're the only ones watching them eat? Think again.
