No contest, no winner, no beer?
However he’ll have a beer anyway!
UC Davis distinguished professor Artwork Shapiro, Division of Evolution and Ecology, did not sponsor his annual public “Beer for a Butterfly” contest this 12 months however he recorded his first-of-the-year sighting of a cabbage white butterfly, Pieris rapae, at 1:25 p.m. on Wednesday, Jan. 19 in West Sacramento close to a railroad embankment.
“Pop Goes the Pieris!” Shapiro emailed to his colleagues.
And it was precisely the day that his colleague-collaborator Matt Forister, the Trevor McMinn Endowed Professor in Biology, Basis Professor, on the College of Nevada, calculated it might be sighted.
Forister, who obtained his doctorate in ecology in 2004 at UC Davis, finding out with Shapiro, crafts “The Flight of the First Butterfly” graphics, utilizing Shapiro’s statistics. “And…. as if we had coordinated efforts (which we did not), this is the graph!” Forister wrote in an e-mail. “Artwork, you nailed it proper on the regression line this time, you deserve an additional beer.”
Shapiro, who maintains a analysis web site at http://butterfly.ucdavis.
For scientific functions, Shapiro seeks the primary cabbage-white-butterfly-of-the 12 months within the three-county space of Yolo, Sacramento and Solano. The competition is often known as “Suds for Bugs.” The conventional guidelines: Catch a reside cabbage white butterfly within the wild in a kind of three counties, ship it reside to his division in Storer Corridor, UC Davis (with the complete knowledge, precise time, date and placement of the seize) and if it is the primary of the 12 months, the winner receives a pitcher of beer or its equal.
Because of COVID-19 pandemic precautions, nevertheless, Shapiro hasn’t sponsored the competition for 2 years. However he is recorded the primary ones he is seen.
In his Jan. nineteenth e-mail documenting the sighting, Shapiro wrote:
“As we speak was a beautiful day in West Sacramento–no excessive or center clouds for the primary time in seemingly endlessly. The positioning has the heaviest midwinter Crucifer bloom in a few years. So as of abundance: Brassica kaber (wild mustard), Raphanus (wild radish), and B. campestris (discipline mustard). Additionally in bloom: Amsinckia (fiddlenecks) and some Erodium (filaree) and (Lamium amplexicaule) giraffe heads. It seems like late February and even March. The twigs on almond are coloring up. No different tree motion famous but! 61F, N wind 5-10 mph however blocked by the RR embankment. It felt fairly heat on the sheltered lee facet, however within the open, uncovered to the wind, it did not.
“At 1:25 p.m., I encountered a male rapae dorsal-basking; it took flight directly. Since there is no such thing as a contest once more this 12 months I had no internet and there’s no specimen. However there we’re…” (He additionally noticed a Vanessa atalanta or pink admiral butterfly, “so 2 species, 2 bugs,” he wrote.)
P. rapae inhabits vacant tons, fields and gardens the place its host vegetation, weedy mustards, develop. The male is white. The feminine is commonly barely buffy; the “underside of the hindwing and apex of the forewing could also be distinctly yellow and usually have a grey solid,” Shapiro says. “The black dots and apical spot on the upperside are typically faint and even to vanish actually early within the season.”
Shapiro normally wins his personal contest as he is aware of the place to search out them. Over the past 5 years, the competition statistics embrace:
- 2022, Jan. 19: Artwork Shapiro collected his first of the 12 months at 1:25 p.m. in West Sacramento (no contest held attributable to COVID precautions)
- 2021, Jan. 16: Shapiro collected his first of the 12 months at 1:55 p.m. Jan. 16 on the UC Davis campus, Yolo County (no contest held, attributable to COVID precautions)
- 2020, Jan. 30: Shapiro recorded his first of the 12 months at 11:16 a.m. on Jan. 30 in Winters (he did not internet the butterfly so he stated “no winner”)
- 2019, Jan. 25: Shapiro collected the winner at 1:12 p.m., Jan. 25 close to the Suisun Yacht Membership, Solano County.

Since 2010, a lot of the successful butterflies have been collected in West Sacramento:
- 2017: Jan. 19: Shapiro collected the winner on the UC Davis campus
- 2016: Jan. 16: Jacob Montgomery, UC Davis graduate pupil, 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

- 2010: Jan. 27: Shapiro collected the winner in West Sacramento
Shapiro has monitored butterfly inhabitants developments on transects throughout central California since 1972 and data the data on his analysis web site at http://butterfly.ucdavis.edu/. His 10 websites stretch from the Sacramento River Delta by way of the Sacramento Valley and Sierra Nevada mountains to the excessive desert of the Western Nice Basin. The biggest and oldest database in North America, it was not too long ago cited by British conservation biologist Chris Thomas in a worldwide examine of insect biomass.
In its larval type, the cabbage white butterfly, generally known as “the imported cabbageworm,” is a pest of cole crops. “Cabbageworm larvae chew massive, irregular holes in leaves, bore into heads, and drop greenish brown fecal pellets that will contaminate the marketed product,” in response to the UC Statewide Built-in Pest Administration Program. “Seedlings could also be broken, however most losses are attributable to injury to marketed elements of the plant.”
