Art Shapiro didn't think Friday would be the day, but his former grad student called it perfectly.

"Today should not have been the day," Shapiro said, noting a forecast of clouds and possible rain. "The first cumulus formed right at 11. At 11:23 I spotted a male Pieris rapae dorsal basking (sunbathing) on low vegetation. As I approached to collect it, a small cumulus occluded the sun and it closed its wings over its back 鈥 allowing me to just pick it up without using my net at all, and drop it into a glassine envelope. It turned out that that was the ONLY cloud that crossed the sun in the next 2陆 hours!"
The cabbage white butterfly needs a string of warm days before it can emerge each year, and Shapiro has been tracking its first flight date for decades as a way to measure how animals respond to climate change. Last year, University of Nevada, Reno, Professor Matt Forister, who studied under Shapiro as a Ph.D. student, predicted Jan. 19 would be this year's first-flight date.
"For the record, next year you will find it on the 18th," Forister told Shapiro in an email last week.
