Butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, monitors butterfly populations throughout the Central Valley, including Gates Canyon, Vacaville, Solano County.
Gates Canyon is one of his "stomping" grounds, or "monitoring" grounds.
And that's where we saw about half-a-dozen butterflies fluttering on Jupiter's Beard (Centranthus ruber), also known as Red Valerian. The perennial is native to the Mediterranean region.
The pipevine swallowtail (Battus philenor) is what Shapiro calls "the signature riparion butterfly of our region (Northern California), occurring along streams in foothill canyons and on the Central Valley floor, essentially everywhere its only host plant, California pipevine or Dutchman's Pipe, Aristolochia californica, occurs."
"This species is warningly colored and inedible to vertebrate predators," Shapiro says on his website. "It derives its protection from the toxic aristolochic acids produced by the host, which it sequesters; females even pass these along to the eggs, which are also protected (and are brick red, laid in bunches of up to 20, and quite conspicuous).
Brick-red eggs? That must be a sight and a delight to see!
You can read more about the pipevine swallowtail on his website.
The first time we ever saw a pipevine swallowtail, it was in the clutches of a hungry praying mantis. (See photo on my Flickr site.)
So it's good to see it "whole."

When I last met up with a pipevine swallowtail, it wasn't faring well.
In fact, I didn't recognize it as a pipevine swallowtail (Battus philenor), no thanks to it being in the clutches of a hungry praying mantis.
Mantids have to eat, too, but I'd prefer they express an culinary interest in pests such as spotted cucumber beetles instead of beneficial insects.
On his website, butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis, calls the pipevine swallowtail "the signature riparian butterfly of our region, occurring along streams in foothill canyons and on the Central Valley floor, essentially everywhere where its only host plant, California pipevine or Dutchman's pipe, Aristolochia californica, occurs."
If you head out to the Storer Garden in the UC Davis Arboretum, you might see a pipevine swallowtail catching the breeze, stopping here and there to nectar a plant.
Maybe this time a praying mantis will catch something else.

Robert Bugg saw it first.
That’s entomologist Robert L. Bugg.
Bugg, who received his doctorate in entomology at UC Davis, does research on the biological control of insect pests; cover crops; and restoration ecology.
And he saw it first.
“Look,” he said. “That praying mantis just bit the head off a pipevine swallowtail butterfly.”
We were part of a field tour, “Yolo County Field Tour of Native Bee Habitat on Working Lands.” Held Wednesday, Aug. 27 and organized by the Native Pollinators in Agriculture Project, the field tour drew representatives from the U.S. Department of Agriculture, California Department of Agriculture, California EPA, and farmers from throughout the country.
We visited seven sites: The Farm on Putah Creek, Butler Farm, Good Humus Farm, Cache Creek Conservancy, Muller Farms, Hedegrow Farms, and the Pioneer Hybrid Seed Farm.
I brought along my camera and a macro lens to capture photos of native pollinators, such as long-horned bees, sunflower bees, sweat bees and bumblebees.
We saw the green praying mantis, disguised as a flower stem or blade of grass, at The Farm on Putah Creek.
It had just snared a pipevine swallowtail butterfly (Battus philenor).
It was survival of the fittest, and the matnis was more than fit. Now he was enjoying a morning meal at the expense of a fluttering butterfly.
The praying mantis (sometimes called a "preying matnis") is an ambush predator. It lies in wait for unsuspecting dinner to arrive.
Mr. Mantis grasped the butterfly in his spiked forelegs and chewed off the head.
It was a good day for a praying mantis, a bad day for a butterfly.
