If you've been looking for that cabbage white butterfly in the three-area county of Sacramento, Yolo and Solano to win UC Davis Professor Art Shapiro's "Beer for a Butterfly" contest, there's still hope.
Shapiro hasn't found it, either.
Butterflies aren't flying due to the elements: the rain, the cold and the fog.
Shapiro, distinguished professor of evolution and ecology launched the "Beer for a Butterfly" contest back in 1972 as part of his scientific research. If you collect the first cabbage white butterfly (Pieris rapae) of the year, you can trade "the bug for suds."
Shapiro is offering a pitcher of beer (or its equivalent) for the first cabbage white butterfly collected in 2018 in any one of the three counties. “Since 1972, the first flight has varied from Jan. 1 to Feb. 22, averaging about Jan. 20,” he says.
The butterfly inhabits vacant lots, fields and gardens where its host plants, weedy mustards, grow. What does it look like? It's a white butterfly with black dots on the upperside (which may be faint or not visible in the early season). It inhabits vacant lots, fields and gardens where its host plants, weedy mustards, grow. 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 said. “The black dots and apical spot on the upperside tend to be faint or even to disappear really early in the season.”
In its caterpillar stage, Pieris rapae is a pest. (See cabbageworm on the UC Statewide Integrated Pest Management Program website.)
Meanwhile, the contest rules include:
- It must be an adult (no caterpillars or pupae) and be captured outdoors.
- 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.)
- Shapiro is the sole judge.
Shapiro, who is in the field more than 200 days of the year, monitoring butterflies of central California (see his website), knows where to find the cabbage whites and usually wins the contest. He has been defeated only four times since 1972--and all by UC Davis graduate students.
The professor collects many of the winners in mustard patches near railroad tracks in West Sacramento, Yolo County. Over the last eight years, five came from West Sacramento; two in Davis, Yolo County; and one in Suisun, Solano County.
The dates and locations:
- 2017: Jan. 19: Art Shapiro collected the winner on the UC Davis campus
- 2016: Jan. 16: Jacob Montgomery, UC Davis graduate student, collected the winner in west Davis
- 2015: Jan. 26: Shapiro collected the winner in West Sacramento
- 2014: Jan. 14: Shapiro collected the winner in West Sacramento
- 2013: Jan. 21: Shapiro collected the winner in West Sacramento
- 2012: Jan. 8: Shapiro collected the winner in West Sacramento
- 2011: Jan. 31: Shapiro collected the winner in Suisun, Solano County
- 2010: Jan. 27: Shapiro collected the winner in West Sacramento
The search continues!

If you collect the first live cabbage white butterfly (Pieris rapae) of 2015 in Yolo, Sacramento or Solano counties and have it verified as the winner, you'll get a pitcher of beer or its equivalent.
Arthur Shapiro, distinguished professor in the UC Davis Department of Evolution and Ecology, is sponsoring his annual “Beer for a Butterfly” contest to draw attention to Pieris rapae and its first flight.
The contest, launched in 1972, is all part of Shapiro's four-decade study of climate and butterfly seasonality. “It is typically one of the first butterflies to emerge in late winter. Since 1972, the first flight has varied from Jan. 1 to Feb. 22, averaging about Jan. 20.”
"I do 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, usually wins his own contest. In 2014, he netted the winning butterfly at 12:20 p.m. Tuesday, Jan. 14 in West Sacramento, Yolo County. It ranked as "the fifth or sixth earliest since 1972."
The professor, fellow of the American Association for the Advancement of Science, the Royal Entomological Society and the California Academy of Sciences, said the cabbage white butterfly inhabits vacant lots, fields and gardens where its host plants, weedy mustards, grow.

Shapiro has been defeated only three times since 1972. And all were his graduate students. Adam Porter defeated him in 1983; and Sherri Graves and Rick VanBuskirk each won in the late 1990s.
Shapiro maintains a website on butterflies, where he records the population trends he monitors in Central California. He and biologist/writer/photographer Tim Manolis co-authored A Field Guide to Butterflies of the San Francisco Bay and Sacramento Valley Regions, published in 2007 by the University of California Press.

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!”

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.
