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.”
Cabbage White Butterfly
Especially when it nectars from catmint (Nepeta) in the early evening, as the sun drops low in the horizon.
Butterfly expert Art Shapiro, professor of ecology and evolution at the University of California, Davis, says the species was introduced in southern Canada in the 1850s. "The great lepidopterist Samuel H. Scudder traced its spread, but was unable to resolve the history on the West Coast," he writes on the website, Art's Butterfly World.
"It was not in San Francisco in the early 1880s, but was abundant by the time of the earthquake (1906)."
Just look at it now. It's everywhere. In fact, every year Shapiro sponsors a contest to see who can find the first cabbage white of the year in the Davis-Sacramento area.
He usually wins.
The cabbage white butterfly (Pieris rapae) looks like a Lady in White when she perches on catmint.
The colors are striking: A long, flowing white gown nestled among the rich lavender blossoms and earthy green leaves.
UC Davis Butterfly expert Art Shapiro says this insect flies an average of 44 weeks of the year in the Davis-Sacramento area. It seems to particularly love the catmint in our garden.
Last night, however, it was flying in our kitchen.
There is no catmint in the kitchen.
There is only a cat.
The confused butterfly probably entered the kitchen through an open door--or the cat door.
My mission: Rescue the butterfly bouncing around in the kitchen and let it go before the cat, aka Xena the Warrior Princess, developed a culinary interest in it.
Back to the catmint it went. I did not take it to Shapiro and ask "Did I win?"
You see, every year Shapiro sponsors a cabbage white contest in the Davis-Sacramento area. The first person who delivers a cabbage white to him, starting the first of the year, wins a pitcher of beer. The contest always ends in January or February.
"Almost every year," he says, "someone brings one in May or June and asks 'Did I win?'"
No losers this time, though. The Lady in White won.
She won the how-to-get-out-of-the-kitchen-unscathed-and-back-to-the-catmint contest.
