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.
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.
The white butterfly, with black dots on the upperside (which may be faint or not visible in the early season), inhabits vacant lots, fields and gardens where its host plants, weedy mustards, grow. It is typically one of the first butterflies to emerge in late winter.
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 says. “The black dots and apical spot on the upperside tend to be faint or even to disappear really early in the season.”
Shapiro 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. 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, has been defeated only three times since 1972. And all were by his graduate students. Adam Porter defeated him in 1983; and Sherri Graves and Rick VanBuskirk each won in the late 1990s.

In the bug world, we're all grateful for the people who study insects, monitor them, and share information to impart scientific data and help save declining species.
Take butterfly expert Art Shapiro, professor of ecology and evolution at the University of California, Davis (of Art's Butterfly World).
How he does it, we'll never know, but he has monitored butterflies in the area for more than three decades and knows when a population is declining or increasing.
On a trip to Vacaville on Nov. 12, Shapiro discovered six gulf fritillaries (Agraulis vanillae) in gardens on Buck Avenue, and one at the base of Gates Canyon (that's only the second he's seen; the first he saw in May of 1984).
That's great news!
"I suspect the colony has expanded into the upscale hillside neighborhood off Foothill but had no time to go looking," Shapiro commented.
Meanwhile, he says, there are fewer gulf frits in Sacramento this year than in the last two years.
The gulf frit is one of the showiest butterflies in California. The bright orange-red butterfly, with a wingspan that can reach four inches, was first recorded in the Bay Area before 1908. Shapiro says it became established there only in the 1950s.
The last time we saw gulf frits in Vacaville was a couple of months ago, on Sept. 14. They were all over a passionflower vine (Passiflora)--the adults, the pupae, the larvae and the eggs--in a Buck Avenue garden. Later we saw several nectaring lantana.
Now they appear to be expanding their territory in Vacaville.
We all ought to be attracting them! The larval hosts include passionflower vines, such as the maypop (Passiflora incarnata), blue passionflower (P. caerulea), and corky-stemmed passionflower (P. suberosa). As an adult, the gulf frit nectars on such plants as lantana (Lantana camara), tall verbena (Verbena bonariensis), pentas (Pentas lanceolata), drummond phlox (Phlox drummondi) and something called "tread softly" (Cnidosculous stimulosus).

When award-winning photographer Teresa Willis of Vacaville encountered a red caterpillar on a dirt road at about 6000 feet in a canyon north of Paradise Valley, Nev., she did what photographers do--she captured an image of it.
And posted it on her Facebook page where some of her friends likened it to the Oscar Mayer weiner.
The caterpillar is indeed red. Bright red. Well, what is it?
Renowned butterfly expert Art Shapiro of UC Davis, who knows about such things, says it is the larvae of an owlet moth (family Noctuidae) "and the species is probably Noctuid."
"It's infested with the parasitic nematode Heterorhabditis bacteriophora, a generalist parasite of insect larvae, which it turns bright red," Shapiro says. "Experiments have shown that this acts as a warning color, deterring visual predators (such as birds) from eating them (and the nematodes in the process)."
Hardly any Lepitoptera escapes identification from Art Shapiro, who maintains the popular website, Art's Butterfly World at http://butterfly.ucdavis.edu/ and is a UC Davis professor of evolution and ecology.
As for Teresa Willis (see more of her work at http://www.redbubble.com/people/teresalynwillis), you can say she got the red out.

In the big, beautiful butterfly world, the Fiery Skipper stands out as the most common urban butterfly in California.
It may not be as showy as the Monarch, the Gulf Fritilliary and the Painted Lady, but the Fiery Skipper (Hylephila phyleus) holds its own.
Butterfly guru Art Shapiro, professor of evolution and ecology at UC Davis, describes it as "California's most urban butterfly, almost limited to places where people mow lawns. Its range extends to Argentina and Chile and it belongs to a large genus which is otherwise entirely Andean."
"Here in California, the oldest Bay Area record is only from 1937," he writes on his butterfly website. "At any rate, it is multiple-brooded, and appears to experience heavy winter-kill in most places; scarce early in the season, it spreads out from local places where it survived, gradually reoccupying most of its range by midsummer and achieving maximum abundance in September and October."
It breeds mostly on Bermuda grass (Cynodon dactylon), Shapiro says.
We've seen the adults nectaring on sedum, lantana, zinnias and Mexican sunflowers (Tithonia) at the half-acre bee friendly garden, the Häagen-Dazs Honey Bee Haven, located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, University of California, Davis. It's like their favorite restaurant where they can order nectar (take-out, please!) from sedum, zinnias, catmint and those glorious Mexican sunflowers.
Since the Fiery Skippers don't take kindly to cold winters, let's enjoy them while we can.

The Gulf Frit is definitely back.
Back in September of 2009, butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis, excitedly announced the re-appearance of the Gulf Fritillary butterfly (Agraulis vanillae) in the Sacramento metropolitan area after a four-decade absence, and in the Davis area after a 30-year absence.
It's a tropical and subtropical butterfly with a range that extends from the southern United States all the way to central Argentina.
The Gulf Frit is a beautiful butterfly with bright orange-red wings, spangled iridescent silver on the underside, and a four-inch wingspan.
The larvae or caterpillars of the Agraulis vanillae feed on the leaves of the passion flower vine; they eat "many but not all species of the genus Passiflora," Shapiro says. "There are no native members of this genus in the state of California, but several are widely cultivated in gardens."
No one knows exactly when the first Gulf Frit first arrived in California, but "it was already in the San Diego area by about 1875, Shapiro says, and it was first recorded in the San Francisco Bay Area around 1908.
The showy butterfly colonized both south Sacramento and the Winding Way/Auburn Boulevard area in the 1960s but by 1971 "apparently became extinct or nearly so," recalled Shapiro, who moved to the Davis area in 1971.
The butterfly can breed where there is a "critical mass" of these plants in a town or neighborhood," he told us back in 2009.
Well, there's a thriving passion flower vine behind a west Vacaville residence that makes one think: "Critical mass!"
On one recent sunny afternoon, we spotted about 10 to 12 Gulf Frits breeding on the vine. Squadrons of brightly colored orange and black caterpillars munched on the leaves.
Yes, the Gulf Frit is alive and well.
Very alive and very well.
So if you have a passion for the Gulf Frit, plant Passiflora.
Plant it and they may come.
