Two's company. Three's a crowd?
Sometimes we wish it were half a dozen.
Last July we were admiring two newly emerged Gulf Fritillary butterflies on Mexican sunflowers (Tithonia) when a Western Tiger Swallowtail fluttered down, seemingly out of nowhere, to occupy the same sunflower as one Gulf Frit.
The Gulf Fritillary (Agraulis vanillae) and the Western Tiger Swallowtail (Papilio rutulus) eyed each other for a few seconds. Then in the way of the West ("This town isn't big enough for the both of us") the tiger spread its wings and took off.

The Western tiger swallowtail (Papilio rutulus) is the kind of butterfly that combines steel with silk.
It's a tough critter. Often you'll see it with its wings clipped by a predator--maybe a bird or a praying mantis.
Then when you see it glide around, landing on Jupiter's beard, it's the epitome of grace.
The magnificent butterfly is found throughout much of western North America, from British Columbia to North Dakota in the north to Baja California and New Mexico in the south. We've seen it nectaring not only on Jacob's beard, but zinnias, Mexican sunflower (Tithonia), California buckeye but thistles, too.
Kite makers, dress makers and tattoo artists mimic this colorful yellow-winged butterfly with its bold black stripes and ll orange and blue spots on its swallow tail.
This one favored Jupiter's beard on Gates Canyon Road, Vacaville, but if you look closely you'll see that a predator tried to give it a clean shave.

If I were in charge of a praying mantis' daily diet, I would enforce one stringent rule: "Please don't eat the pollinators! Do not, I repeat, target the bees or butterflies. Leave them alone!"
The mundane menu would include flies, gnats, stink bugs, aphids, mosquitoes, yellowjackets, grasshoppers, leaffooted bugs and not much else.
But since I'm not likely to be employed as the chef of a praying mantis' diet, these predators can--and do--eat what they want.
This morning I encountered a praying mantis perched on a Mexican sunflower (Tithonia) in our bee garden. He saw me. He swiveled his head about 180 degrees as he followed me with his five keen eyes--two large compound eyes and three smaller simple eyes. Hmm, not potential prey. He went about "praying"--bending his front legs and "assuming the position."
Okay, I thought. "Go catch a fly, gnat, stink bug, aphid, mosquito, yellowjacket, grasshopper or leaffooted bug."
So, what did he catch? A beautiful Western tiger swallowtail (Papilio rutulus) which made the fatal mistake of landing on his flower.
Yes, a praying mantis has to eat. Yes, he was hungry. Yes, it's nature. But why not a stink bug?
He polished off a butterfly.
"Yummy!" declared a colleague.

It's a joy to see the anise swallowtail (Papilio zelicaon) fluttering around in community gardens, bee gardens and parks.
Last weekend in a Benicia community garden, we spotted this sunny butterfly, as identified by Art Shapiro, distinguished professor of evolution and ecology at UC Davis, who monitors Central California butterflies and posts information on his website, Art's Butterfly World.
Its distinctive yellow, blue and blue colors remind us of the Western tiger swallowtail (Papilio rutulus).
Unlike the Western tiger swallowtail, however, the anise swallowtail has large patches of black on the front portion of its forewing.
You'll see the anise swallowtail around its host plant, anise, Foeniculum vulgare, a weed with a licorice scent. Anise swallowtails breed on the anise and poison hemlock, Conium maculatum, Shapiro says.
Last weekend in Benicia, the anise swallowtail took an interest in wild radish.
Check out the beautiful photos of the anise swallowtail on BugGuide.net, which says it was first described in 1852 by Hippolyte Lucas as Papilio zelicaon. That was during California's Gold Rush Days and a year later, in 1853, settlers introduced the European or Western honey bee to California.

That's when butterfly expert Art Shapiro, professor of evolution and ecology at UC Davis, will be speak at the Northern California Entomology Society meeting, to be held at the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis.
The meeting will begin at 9:15 a.m. with registration for club members and guests, and conclude at approximately 2:30 p.m. The group, which meets three times a year, is comprised of university faculty, researchers, pest abatement professionals, students and other interested persons.
Shapiro will lead off the program at 9:45 a.m. with his talk on “History of the Sacramento Valley Butterfly Fauna.” A noted butterfly expert, he has monitored butterflies for more than 35 years in the Central Valley and maintains Art's Butterfly World website.
Chemical ecologist Steve Seybold of the USDA Forest Service, Davis, and an affiliate of the UC Davis Department of Entomology, will speak on “Goldspotted Oak Borer in California” at 10:30 a.m.
Following the lunch from noon to 1 p.m., Jason Leathers of Pest Detection/Emergency Projects, California Department of Food and Agriculture (CDFA), will cover “Pest Control Approaches and Evaluations on Success of 2012 Insect Eradication Programs in California.”
At 1:45 p.m., Stephen Brown, CDFA, and Anthony Jackson, Animal and Plant Health Inspection Service (APHIS), USDA, will discuss “California and Federal Regulations Concerning Importing Living Plant Pests.”
The society meets three times a year: the first Thursday of February at the California Department of Food and Agriculture (CDFA), Sacramento; the first Thursday of May, at the Harry H. Laidlaw Jr. Honey Bee Research Facility, UC Davis; and the first Thursday of November in the Contra Costa Mosquito and Vector Control District conference room, Concord.
Membership is open to the public; dues are only $10 year. President is Robert Dowell, a staff environmental scientist at CDFA.
More information about the meeting is available from Extension apiculturist Eric Mussen of the UC Davis Department of Entomology. Serving as the society’s treasurer, he can be reached at email@example.com or by (530) 752-0472.
