And we have a winner!
Drum roll...Art Shapiro...
Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, who sponsors the annual Beer-for-a-Butterfly Contest to collect scientific data, snagged the first cabbage white butterfly of the year at 12:30 p.m.. Monday, Jan. 26 in West Sacramento, Yolo County.
“The cabbage white butterfly (Pieris rapae) finally came out today (Jan. 26),” he said.
And, it's a boy!
Shapiro figured this would be the day. Sunshine filtered through the high clouds in the morning, so it was relatively warm when Shapiro set out at 11.15 a.m. for a mustard patch near the railroad tracks. In fact, he was so “sufficiently sure” that Monday would be the day that he took his net “and was prepared to sweep the vegetation with it to kick up any individuals that were sunbathing (“dorsal basking”) in the dilute sunlight in order to raise their body temperature to the level needed for flight.”
But that wasn't necessary. “The sun came out strongly at 12.11 and the butterfly, a male, took wing spontaneously 19 minutes later,“ he related. ““It was a very easy catch; I suspect he emerged this morning (Jan. 26) and that was his first flight.”
Shapiro has sponsored the contest since 1972 to determine when the cabbage white will first emerge in the three-county area of Sacramento, Yolo and Solano. It's all part of his 43-year study of climate and butterfly seasonality. “It is typically one of the first butterflies to emerge in late winter.”
Although the first flight of the cabbage white has been as late as Feb. 22, it is emerging earlier and earlier as the regional climate has warmed, said Shapiro. “There have been only two occasions in the 21stcentury in which it has come out this late: Jan 26, 2006 and Jan 31, 2011.
“It's obvious that a dry January doesn't guarantee an early emergence!” Shapiro said. ”The very wet December of 2014 laid the groundwork for tule fog this month, which we hadn't really seen since the drought began. The cold, foggy weather certainly played a role in delaying emergence.”
Ten minutes after collecting the cabbage white, a second species, the mourning cloak (Nymphalis antiopa) showed up. “It hibernates as an adult and is always an early flier, but this was its first record on the floor of the Sacramento Valley this year—it's been out about two weeks in the lower Coast Range,” Shapiro said.
Five minutes later, at 12.45, a third species showed up: a male fiery skipper (Hylephila phyleus) that landed momentarily literally at Shapiro's feet. It was the earliest he's ever recorded. “This is a much more significant record than the others,” he said, explaining that the fiery skipper “normally is first recorded around here in March or even April. Last year it set a new early record in the Valley—Feb. 21, in Rancho Cordova, Sacramento County.—the only February Valley record in our 43-year database. It was last seen in 2014 on Dec. 1, also in Rancho Cordova. However, there are two January records at the Suisun Marsh, Solano County: Jan. 3, 1996 and Jan. 28, 2000.
Of the fiery skipper, Shapiro noted: “The first was certainly a late carryover of the fall 1995 brood, which was still flying on Dec. 14. “ The species wasn't seen again until the start of the spring brood on March 31, 1996. The 2000 record is more ambiguous. The last Suisun sighting in 1999 was on Dec. 11 and the first spring sighting was very late, May 24, 2000.
“The last fall-brood sighting of the fiery skipper was on Nov. 9, 2014, making it exceedingly unlikely that this was a late individual from that brood,” Shapiro said.
In 2014, Shapiro netted the winning cabbage white butterfly at 12:20 p.m. Tuesday, Jan. 14 in West Sacramento, Yolo County. It ranked as "the fifth or sixth earliest since 1972.”
Shapiro has won the contest every year except three. Graduate student Adam Porter defeated him in 1983; and graduate students Sherri Graves and Rick VanBuskirk each won in the late 1990s.
The contest rules specify that it be an adult (no caterpillars or pupae and that it be captured outdoors. It must be live when delivered to the department office, 2320 Storer Hall, UC Davis.
Shapiro has monitored central California's butterfly populations for 43 years and posts information on his website.

There's something about seeing a butterfly that makes your eyes light up, your smile widen, and your feet feel like skipping.
So when I was over at Kaiser Permanente in Vacaville last Tuesday, I rejoiced at seeing a magnificent anise swallowtail, Papilo zelicaon, fluttering around the lantana flower beds near the entrance.
The butterfly flashed its brilliant yellow and black colors in the morning sun as it glided around the flower bed, touching down occasionally for a sip of nectar.
Such a beautiful, awe-inspiring, glorious creature.
So I did what comes naturally—I pulled the camera out of my bag—somewhat like pulling the rabbit out of a hat because you never know what kind of magic may--or may not--happen. Assuming my best "non-predator posture," I slowly trailed it from blossom to blossom, dropping down to capture its image.
It was then that I noticed a woman sitting on a nearby bench, smiling, as she watched the photographer follow the butterfly.
“I love butterflies," she said. "I collect butterflies—jewelry. I would never collect the real thing. They're too beautiful.”
“Me, either,” I said. “I try not to disturb them—I just photograph them.”
Half an hour later, I returned to the area only to observe a stricken look on the woman's face.
“You have the last photo of that beautiful butterfly," she said. "A bird ate it."
And right in front of the managed health care facility.

There's a good reason why lepidopterists call the Gulf Fritillary (Agraulis vanillae) "showy."
Its bright orange-red wings, spangled iridescent silver on the underside, and a four-inch wingspan all point to "showy."
The Gulf Frit is a tropical and subtropical butterfly with a range that extends from the southern United States all the way to central Argentina. Back in September of 2009, butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis, excitedly announced the re-appearance of the Gulf Frit the Sacramento metropolitan area after a four-decade absence, and in the Davis area after a 30-year absence.
Yes, the Gulf Frits are back. Thankfully, they've returned to creating a nursery of sorts on our passionflower vine and their host plant (Passiflora). The eggs, caterpillars, chrysalids and adults are a delight to see.
However, the cycle of life is in full force in our bee garden. The hawks are eating the scrub jays; the scrub jays are eating the bees; and the bees are just trying to mind their own "bee business" by collecting pollen and nectar for their colonies. Always opportunists, the jays nesting in our trees are also targeting the butterflies and caterpillars. (So, too, are such predators as spiders and praying mantids.)
Today we captured several images of a Gulf Frit in flight. If you look closely, you'll see that part of her wing is missing.
That was a close one!

In the entomological world, we call that a "two-fer."
Two insects in the same photo.
Sunday morning we spotted a fiery skipper butterfly (Hylephila phyleus) on an artichoke leaf. It was warming its flight muscles, maybe to flutter over to the lavender for a sip of nectar.
Next to it--we almost missed it--was a damselfly, apparently doing the same thing. Or maybe it was waiting for an aphid or a gnat or ant to come along. They eat small, soft-bodied insects.
The skipper: a member of the family Hesperiidae, order Lepidoptera.
The damselfly: a member of the suborder Zygoptera, order Odonata.
Two entirely different orders, but both belonging to the class Insecta.
And sharing an artichoke leaf on a Sunday morning.

The painted ladies are on move.
Scores of painted ladies (Vanessa cardui) are now migrating north from their overwintering sites near the U.S. Mexico border.
"Fascinatingly, they arrived in Prescott, Ariz., the same day (as the ones spotted in Benicia)," said butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis. "I think they're all from south of the border." The annual migration north varies, but can take place as early as late January and as late as mid-April.
The painted ladies spend the winter in the desert, where in the late winter, they breed on desert annual plants, Shapiro says. The adults emerge in February or March and immediately migrate into the Central Valley and foothills, where they breed. Around May, here in the Central Valley, you'll see the caterpillar offspring munching on borage, thistles, fiddleneck and mallows. Then the adults head toward the Pacific Northwest.
"The painted lady moves northward in a generational wave as the season progresses," Shapiro says on his website. "Frequently it disappears altogether from the lowlands in summer. Beginning in August the movement reverses and butterflies head south toward the desert wintering grounds."
"There is no evidence that this species overwinters successfully anywhere in our area, except for very rare individuals maturing in midwinter from really late autumnal larvae."
The painted lady migration may not be as popular as the monarch (Danaus plexippus) migration, but it's fascinating just the same.
Shapiro, who has monitored the butterfly population of California's Central Valley for 42 years, will be speaking at noon on Monday, March 24 on "Ecological Communities and the March of Time" in the Commonwealth Club, 595 Market St., San Francisco.
