Pop goes the Pieris.
So wrote professor Art Shapiro of the UC Davis Department of Evolution and Ecology from his office in Storer Hall.
Yes, he won his own contest again.
Every year since 1972, the butterfly expert has sponsored a beer-for-a-butterfly contest to see who can find the first cabbage white butterfly (Pieris rapae) of 2012 in the three-county area of Sacramento, Yolo and Solano.
He netted a newly emerged male at 11:50 a.m. on Sunday, Jan. 8 in in West Sacramento, Yolo County, to claim his own prize.
Shapiro immediately announced he would take his graduate students and their significant others out for a beer in a few days to celebrate. His students are typically his fiercest competitors in the contest, which is designed to aid in his studies of biological response to climate change.
Sunday’s capture date is the second earliest of record in 40 years, the earliest being Jan. 4, 1990. Shapiro said it reflects “the extraordinary sunny and dry weather that has persisted all winter, with warm afternoons, frosty nights, and little cloudiness or fog.”
“There have been numerous high-temperature records set in northern California, both in the valleys and in the Sierra Nevada, “ Shapiro said. “The abnormal conditions cannot be linked causally to global warming but are related somehow to the current La Nina, now in its second year.”
Shapiro noted that many regional first-flight records for butterflies were set during the severe drought of 1975-76, before “ the signature of global warming was observed.”
“In 1976 we had species flying at the end of January that normally come out in March,” Shapiro observed. “If the current weather pattern continues another two weeks, all those records will be at risk.”
He also pointed out that due to the lack of rainfall, germination of herbaceous plants has been very poor. “If butterflies and other insects are tricked by the weather into emerging early, the resources they need will simply not be there!”
Showing his keen sense of humor, Shapiro joked that politicians of a certain persuasion had something to say about the contest. "Despite my willingness to share the prize, news that I had won again drew harsh criticism" from them, he said. "Despite their own differences, they unanimously pointed out that I teach evolution and study climate change, both of which they consider to be hoaxes."
Shapiro, a fellow of the American Association for the Advancement of Science, the Royal Entomological Society and the California Academy of Sciences, maintains a website on butterflies at http://butterfly.ucdavis.edu/, where he monitors butterfly population trends in Central California. He has surveyed fixed routes at 10 sites since as early as 1972. They range from the Sacramento River delta, through the Sacramento Valley and Sierra Nevada mountains, to the high desert of the western Great Basin. The sites, he said, represent the great biological, geological, and climatological diversity of central California.
Meanwhile, we're waiting for the 2013 beer-for-a-butterfly contest. We think we know who will win it! The winner's name starts with an "A."

We've been waiting with bated breath for butterfly expert Art Shapiro, professor of evolution and ecology at UC Davis, to announce he's found the first Pieris rapae of the year.
Not so.
Not yet.
Every year since 1972 Shapiro has challenged the residents of Sacramento, Yolo and Solano to find the first cabbage white butterfly and bring it to him. First one to capture the butterfly in one of the three counties gets a pitcher of beer (or its cash equivalent).
Shapiro sponsors the annual contest to draw attention to Pieris rapae and its first flight. "I am doing long-term studies of butterfly life cycles and climate. Such studies are especially important to help us understand biological responses to climate change. The cabbage white is now emerging a week or so earlier on average than it did 30 years ago here."
Shapiro usually wins his own contest. He's lost only three times since 1972.
If you want to compete, be sure to check the rules.
Today he went a'hunting in West Sacramento. "What a grand and glorious April day it was!" he said. "Sixty-five degrees in West Sacramento, sunny, light and variable wind...a perfect day to get the first Pieris rapae of 2012. But I didn't. I spent 3-1/2 hours in West Sacramento checking every one of the more than 20 wild radish plants in bloom at least 3 times. If there had been a rapae there, I would have seen it! All I saw was two Vanessa annabella. The drama continues."
I looked through my Solano County photos of cabbage whites and noticed a two-at-a-time image, taken Sept. 7, 2008 in our backyard.
My camera, which can shoot eight frames a second, caught the images on the fly.
Art Shapiro can catch them with his hands. And does.

Beer for a butterfly.
Now that's an interesting concept.
That’s what you’ll get—or the cash equivalent—if you collect the first cabbage white butterfly (Pieris rapae) of 2012 in an area encompassing Yolo, Solano or Sacramento counties.
Professor Art Shapiro of the UC Davis Department of Evolution and Ecology has issued the first call for his annual “Catch-a-Cabbage-White-Butterfly-Win-a-Pitcher-of-Beer” contest, which he launched in 1972.
The butterfly must be delivered live to the office of the Department of Evolution and Ecology, 2320 Storer Hall.
Since 1972 the first flight has varied from Jan.1 to Feb.22, averaging about Jan.20. The 2011 find was on Jan. 31.
Shapiro, a noted butterfly expert who maintains a website on butterflies, usually wins the contest. He caught the first cabbage white butterfly of 2011 at 1:21 p.m., Monday, Jan. 31 in Suisun City, Solano County.
The rules:
1. The butterfly must be captured in one of three California counties: Yolo, Solano or Sacramento on or after Jan. 1, 2012
2. It must be an adult (no caterpillars or pupae) and be captured outdoors.
3. It must be brought in alive to the department office, 2320 Storer Hall, UC Davis, during work hours, 8 a.m. to 5 p.m., Monday through Friday, with the full data (exact time, date and location of the capture) and your name, address, phone number and/or e-mail. The receptionist will certify that it is alive and refrigerate it. (If you collect it on a weekend or holiday, keep it in a refrigerator; do not freeze. A few days in the fridge will not harm it.
4. Other species are ineligible.
5. Professor Shapiro’s judgment is final. All butterflies submitted may be retained as vouchers.
The white butterfly, with black dots on the upperside (which may be faint or not visible in the early season), inhabits vacant lots, fields and gardens where its host plants, weedy mustards, grow. It is typically one of the first butterflies to emerge in late winter.
The male is white. The female is often slightly buffy; the "underside of the hindwing and apex of the forewing may be distinctly yellow and normally have a gray cast,” Shapiro says. “The black dots and apical spot on the upperside tend to be faint or even to disappear really early in the season.”
Shapiro sponsors the annual contest to draw attention to Pieris rapae and its first flight. "I am doing long-term studies of butterfly life cycles and climate. Such studies are especially important to help us understand biological responses to climate change. The cabbage white is now emerging a week or so earlier on average than it did 30 years ago here."
Shapiro, who is in the field more than 200 days a year, has been defeated only three times since 1972. And all were by his graduate students. Adam Porter defeated him in 1983; and Sherri Graves and Rick VanBuskirk each won in the late 1990s.

Nothing but net? No, no net.
We have a winner in the 40th annual Cabbage White Butterfly Competition, sponsored by butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis. Shapiro traditionally offers a pitcher of beer (or its equivalent) for the first cabbage white of the year collected in Yolo, Solano or Sacramento counties and delivered to the office of the Department of Evolution and Ecology, Storer Hall.
And the winner is...drum roll, please...Art Shapiro. Fact is, he's won the contest every year except for three.
And this year, he caught the prize-winner without a net.
Shapiro nabbed the first cabbage white butterfly (Pieris rapae) of 2011 at 1:21 p.m. today (Monday, Jan. 31) in Suisun City, Solano County. Last year he caught the first one on Jan. 27 in West Sacramento.
Although Suisun City is his oldest sampling site, dating back to 1972, Shapiro does not recall ever finding the first-of-the-year cabbage white there before. Precisely because of that, Shapiro traveled to Suisun at midday Monday without a net.
He saw it, a male, at 1:09 p.m. And he had no net.
“It was taking nectar from flowers of field mustard (Brassica kaber) along a 6-foot-high fence facing the sun,” Shapiro said. “I tried twice to catch it by hand but failed, and it soared over the fence into someone's back yard.”
"But I knew it wasn't as warm on the other side, and there probably wasn't anything in bloom either. So I figured I'd just wait and see if it came back. It did--and I got it on my first try."
Asked how he could catch an active butterfly by hand, Shapiro smiled and said "Experience." A few years ago he caught a very rare all-black mutant of the orange sulphur butterfly the same way.
Shapiro (see his website, http://butterfly.ucdavis.edu) sponsors the annual contest to draw attention to Pieris rapae and its first flight. "I am doing long-term studies of butterfly life cycles and climate," he said. "Such studies are especially important to help us understand biological responses to climate change. The cabbage white is now emerging a week or so earlier on average than it did 30 years ago here."
Shapiro, who is in the field more than 200 days a year, enlists public involvement "because I have that much more confidence that I am tracking the actual seasonality of this common 'bug.'"
Following his find, Shapiro said he took his disappointed grad students out for beer at The Graduate, a local pub, after work. “I usually buy the first pitcher anyway,” he said.
Shapiro has lost only three times in 40 years--and all by his graduate students. Adam Porter found the first cabbage white in 1983; and Sherri Graves and Rick VanBuskirk each claimed the title in the late 1990s.
Interestingly, people contact him as late as June asking if they’ve won.
“No,” he tells them. “Too late.”

It's worth a pitcher of beer or the equivalent if you win Arthur Shapiro's 40th annual Cabbage White Butterfly Competition, which begins Jan. 1, 2011.
Shapiro (right), a noted butterfly expert and a professor in the Department of Evolution and Ecology (EVE) at the University of California, Davis, sponsors the annual contest to draw attention to Pieris rapae and its first flight.
Why does he do this? "I am doing long-term studies of butterfly life cycles and climate," he said. "Such studies are especially important to help us understand biological responses to climate change. The Cabbage White is now emerging a week or so earlier on average than it did 30 years ago here."
Shapiro, who is in the field more than 200 days a year, enlists public involvement "because I have that much more confidence that I am tracking the actual seasonality of this common 'bug.'"
The butterfly must be turned in alive to the receptionist in the Department of Evolution and Ecology, 2320 Storer Hall, UC Davis, during the business hours of 8 a.m. to 5 p.m., Monday through Friday.
The receptionist will certify that it is alive and then notify Shapiro, who will confirm the identification.
Collectors must include the precise location and time of their find (such as corner of Buck Avenue and West Street, Vacaville, Solano County, 7:44 a.m., Jan, 2, 2011) and provide their name and contact information (e-mail and/ or telephone).
"First flight dates in the past have varied between Jan.1 and Feb. 22," Shapiro said. "The first record in 2010 was on Jan. 27. Sight records without a capture are interesting but not eligible to win since the species cannot be verified."
"If you capture a Cabbage White on a weekend or holiday when the EVE office is closed, or cannot deliver it the day you catch it, refrigerate it; do not freeze it," he said. "It will keep up to a few days that way. Again, it must be alive when turned in to be eligible. If no receptionist is on duty when you arrive, ask any member of the EVE office staff to take care of it."
Oh, if you win a pitcher of beer, it's your choice of the brand. If you don't drink or you're a minor, not to worry. You'll get the equivalent in cash.
For more information, contact Shapiro at amshapiro@ucdavis.edu, phone (530) 752-2176, or fax him at (530) 752-1449.
