To Catch a Cabbage White

So you're out roaming the countryside or cityscape in Solano, Yolo or Sacramento counties at the start of the new year and you encounter a Cabbage White butterfly.

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.
