First the lantana, and then the passion flower vine.
The Gulf Fritillary butterflies (Agraulis vanillae) flutter daily around our backyard. They stop for a little nectar from lantana (family Verbenaceae), and then head over to the passion flower vines (genus Passiflora) to breed or lay their eggs.
You can't miss them. The Gulf Frit is a showy, reddish-orange butterfly. Its underside absolutely sparkles in a spangled iridescent silver.
Butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis, and who maintains the website, Art's Butterfly World, says the Gulf Frit was introduced into southern California in the 19th century and first recorded in the Bay Area "before 1908."
It was once prevalent in the Sacramento area in the 1960s, but seemed to have died out by the early 1970s.
Then in 2009, it began making a comeback in the Sacramento area.
It's definitely making a comeback. A beautiful comeback.

There's nothing like seeing an admiral at a marina.
That would be the Red Admiral butterfly, Vanessa atalanta, at the Berkeley marina.
It's often very common in the urban Bay Area, says butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis. The Red Admirals often share sites with West Coast Ladies.
"Both breed on the weed Parietaria judaica (Pellitory) there."
We also saw a West Coast Lady, Vanessa annabella, fluttering around the Red Admiral last Saturday.
But it's the other butterflies that Shapiro is concerned about. "At this time of the year, one used to see Great Coppers (Lycaena xanthoides) up the yin-yang on the 'waste ground' across the marina parking lot, between it and the freeway. Since they made it part of Eastshore Park, it seems to be gone. Typical!"
Other "marina fauna" from back when, he says, included Anise Swallowtails and Large Marbles. "The latter seems to be gone too; it's extinct regionally but there is one population I know of near Concord."
A renowned lepidopterist, Shapiro monitors the butterfly population in Central California and posts information on his website, Art's Butterfly World.
He's the author of the book, Field Guide to Butterflies of the San Francisco Bay and Sacramento Valley Regions, illustrated by Tim Manolis. "The California Tortoiseshell, West Coast Lady, Red Admiral, and Golden Oak Hairstreak are just a few of the many butterfly species found in the floristically rich San Francisco Bay and Sacramento Valley regions," Shapiro writes. He covers and identifies more than 130 species in the book.

But they're doing it too well.
The gulf frittillary butterflies (Agraulis vanillae) are mating and depositing their eggs on our passion flower vines--as we want them to do--but complete metamorphosis always seems to be incomplete. It's supposed to be egg, larva (caterpillar), chrysalis, adult.
But it's really egg, caterpillar, scrub jay food.
The ever-present scrub jays nest in our trees and swoop down periodically to feast on the caterpillars. Now that they have many mouths to feed, they seem to be even more vigilant.
But today, as luck would have it, we noticed several caterpillars tucked beneath the leaves.
Butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, monitors the Central Valley butterfly population, including the gulf frits. In the early 1970s, scientists considered the reddish-orange showy butterfly extinct in the Sacramento/Yolo area. However, since 2000, it's been making a comeback.
Like many butterfly/plant enthusiasts, we planted the passion flower fine (tropical genus Passiflora) to attract them. We watch the gulf frits nectar on the nearby lantana and lay their tiny golden eggs on the passion flower vine.
Sadly, we're not the only ones watching them.

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 firstname.lastname@example.org or by (530) 752-0472.

But such was the case Monday, Jan. 21 for butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis.
See, Shapiro sponsors the annual "Beer for a Butterfly" contest to see who can collect the first white cabbage butterfly of the year in the three-county area of Yolo, Solano and Sacramento. A noted butterfly expert, he's been monitoring the butterflies of Central California for more than three decades and maintains a website, Art's Butterfly World.
Shapiro has sponsored the "Beer or a Butterfly" contest since 1972 to draw attention to the first flight of the butterfly. He awards the winner--usually himself!--a pitcher of beer or its equivalent.
This year he netted the first white cabbage butterfly (Pieris rapae) on President Barack Obama's Inauguration Day, Monday, Jan. 21. Perhaps coincidentally, he also caught the first white cabbage fly of 2009 on President Obama's first Inauguration Day--Jan. 20.
“The constitution mandates the swearing-in for Jan. 20, though it does not require Pieris rapae to emerge on that date,” Shapiro quipped.
“Thank you, Mr. President!”
For the record, Shapiro caught the 2013 winner near railroad tracks in West Sacramento, Yolo County, and the 2009 winner near railroad tracks in Davis, also in Yolo County. (Shapiro’s first catch of 2013 was actually on Jan. 1 at the same West Sacramento site, but “it was a slopover from the fall brood.” Thus, he declared the contest still under way.)
Now the contest is over and Shapiro says that since “Pieris rapae is out, I can ‘stand down.’ It’s now officially spring.”
He declared it spring, and so it is.
Now, the big question: Will Professor Shapiro share his beer with the President?
“I'd be delighted to buy Obama a beer," Shapiro said, "but I suspect he has better things to do with his time!”
