So, they’ve designed a humorous t-shirt inscribed with “Know Your Sticks,” featuring drawings of four sticks: a stick person, a real stick or twig, a Vietnamese walking stick and an Australian spiny stick (family Phasmatidae).
“One of the most popular insects in the Bohart Museum’s live ‘petting zoo’ is the walking stick,” said Fran Keller, who originated the idea of a stick t-shirt, in between studying for her doctoral degree in entomology. “So we thought we’d clarify the sticks.”
Keller designed the shirt, and undergraduate student Ivana Li, president of the UC Davis Entomology Club, drew the illustrations.
The stick person, named Talea persona (Latin for "stick person"), is the kind you might see on a rear windshield, Keller said. The real stick (Twigus stickus) is one you might see in the woods. And the Vietnamese (Medauroidea extradentata) and Australian sticks (Extatosoma tiaratum)? You can see them—and hold them--in the Bohart Museum.
The t-shirts, available in all sizes and many colors, range from $15 (for kids) to $18 (adults) to $20 (adults’ v-neck). They are available online or in the gift shop at the museum, Room 1124 of Academic Surge, located near the corner of La Rue Road and Crocker Lane (formerly California Avenue). Proceeds benefit the museum's educational programs.
The Bohart Museum, directed by Lynn Kimsey, professor of entomology at UC Davis, houses a global collection of more than seven million insect specimens and is the seventh largest insect collection in North America. It is also the home of the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum in 1946.
The Bohart’s regular hours are from 9 a.m. to noon and from 1 to 5 p.m., Monday through Thursday. It is closed to the public on Fridays and on major holidays. Admission is free.
The Bohart Museum's “petting zoo” includes such permanent residents as Madagascar hissing cockroaches and a rose-haired tarantula, in addition to the walking sticks.
Keller suggests that for a novelty photo, stick a walking stick on your "Know Your Sticks" t-shirt, and have a friend photograph the “sticktoitiveness.”
And that’s not something to shake a stick at.
She delighted in the insects on her parents' rose buses--the aphids, the ladybugs, grasshoppers and the caterpillars.
“I would trap those in containers and I kept my tiny companions underneath the bed where I could easily take them out for play and also hide them away from my mother," she recalled. "I knew I liked insects.”
But credit a cricket named Chester with really getting her into entomology.
Chester? He's the main character in George Selden's Newbery award-winning book, A Cricket in Times Square.
Young Ivana encountered the book in the second grade and learned the definition of "entomologist."
"I was pretty thrilled that to find out that there was actually a job in which you get to study insects," related Li, who was born and reared in Monterey Park, near east Los Angeles. "That was the best. It still is.”
After graduating from Schurr High School in Montebello, Li enrolled as an entomology major at UC Davis. Now a fourth-year entomology major and president of the UC Davis Entomology Club, she was just announced as the recipient of the Department of Entomology’s 2012 Outstanding Undergraduate Award.
And well deserved!
Forensic entomologist Robert Kimsey presented her with the coveted award at a recent departmental barbecue. A perpetual plaque, displayed outside the department's administration office on the third floor of Briggs Hall, now bears her name.
Ivana Li does love bugs! When she's not in class, you'll find her working in the Bohart Museum of Entomology, home of more than seven million insect specimens.
Said Lynn Kimsey, director of the Bohart Museum and a professor in the UC Davis Department of Entomology: “Ivana has worked for me for several years. She is a gifted student with many impressive talents, and a maturity well beyond that of her peers. She will go far.”
As for career choices, Ivana Li hasn't’ decided yet, but it will be either “forensics or ecology.”
“Both,” she said, “are appealing at this point in my life.”
Scorpions--to fear or to revere?
The Bohart Museum of Entomology's open house last Sunday drew visitors of all ages who marveled at the scorpions glowing under ultraviolet light.
UC Davis entomology major Alexander Nguyen flashed a UV light on the critters as his audience watched in amazement.
Most--but not all--of the world's scorpions glow under ultraviolet light, says Lynn Kimsey, director of the Bohart Museum, which houses more than seven million insect specimens.
Scorpions are not insects, but arachnids, the same as spiders. Ranging in size from 9 mm to 21 mm, scorpions have eight legs (arachnid alert!) and grasping claws that help conquer their prey. But it's their venom that kills. And all scorpions possess venom.
UC Davis entomologist Bruce Hammock and his lab made the news back in 2003 when they published a study that showed that scorpions produce two venoms: a pre-venom to deter predators and immobilize small prey, and then the good stuff, the powerful venom that's meant to kill.
It's like saving the best for last or waiting for the venom glands to pump and reload, so to speak.
So, why do they glow?
Scientists believe it's because of the fluorescent material found in the scorpion's hard outer covering.
"The fact that they glow serves no physiological function," said Bohart senior museum scientist Steve Heydon. "It's probably a quirk of chemical makeup."
Great quote..."a quirk of chemical makeup."
Most scorpions glow under an ultraviolet light, but now a discovery on Alcatraz Island reveals that a certain species of millipedes will, too.
Forensic entomologist Robert Kimsey of the UC Davis Department of Entomology, who does fly research on Alcatraz, said that bait laced with a non-toxic fluorescent dye to estimate the rat population in February yielded the expected result: the glow of rat urine and feces.
But something else was glowing nearby: millipedes.
Had they consumed some of the rat bait?
No. An experiment at the Bohart Museum of Entomology on the UC Davis campus showed that these millipedes (Xystocheir dissecta (Wood) glow under black lights, just like scorpions.
Lynn Kimsey, director of the Bohart Museum and a professor of entomology at UC Davis, said the species is a relatively abundant species in the Bay Area. “This particular species of millipedes glowed all along, but nobody was paying any attention to it,” she said.
She suspects that the millipedes on Alcatraz Island originated from soil transported over from the nearby Angel Island when “The Rock” was just that—rock with little or no soil.
Meanwhile, if you attend the Bohart Museum's open house from 1 to 4 p.m. on Sunday, June 3 at 1124 Academic Surge, California Drive, you'll see scorpions and millipedes glowing.
And there's something else to draw you in: a special live display of the California dogface butterfly by naturalist/photographer Greg Kareofelas of Davis. If all goes as planned, an adult will emerge from its chrysalis. If this doesn't happen (well, you can't tell a buttterfly when to emerge!) you can watch the life cycle on his PowerPoint presentation, to run continuously throughout the open house.
And, you can ask Kareofelas all about the California dogface butterfly (Zerene eurydice), which, by the way, is close to royalty--it's California's designated state insect.
But this Sunday, June 3, something even more special "may" occur.
That's "may" because a California dogface butterfly "may" emerge from its chrysalis during the Bohart open house, set from 1 to 4 p.m. in 1124 Academic Surge on California Drive.
Naturalist-photographer Greg Kareofelas of Davis, a volunteer at the Bohart, will be showcasing some live California dogface butterflies--and a chrysalis.
Kareofelas is rearing several dogface butterflies (Zerene eurydice). The first adult emerged from its chrysalis on May 28. He’s hoping one will emerge during the open house.
Even if it doesn't, Kareofelas will be presenting a slide show of the butterfly's life cycle. (By the way, Sunday marks the last Bohart open house of the 2011-2012 academic year, and yes, it's free and open to the public.)
Several years ago Kareofelas and entomology doctoral candidate Fran Keller teamed to create a California dogface butterfly poster, which is available for sale in the museum's gift shop.
What about the state insect? What do we know about it?
The high-flying butterfly, found only in California, is rarely seen in the wild. Its main host plant is False indigo (Amorpha californica), a riparian shrub that grows among poison oak and willows and along stream banks, often in steep and isolated canyons. The male has markings on its wings resembling a silhouette of a dog's head. The female is usually solid yellow with a black spot on each upper wing.
The California State Legislature designated the California dogface butterfly as the state insect in 1972. An entomology society in Southern California first proposed this butterfly as the state insect in 1929, but nothing came of it until 1972 when a fourth grade class in Fresno petitioned their state representative, said Tabatha Yang, the Bohart Museum's education and outreach coordinator.
The California dogface butterfly display will be one of the two main attractions at the Bohart's open house, which is themed “Bug Light, Bug Bright, First Bug I See Tonight!” The other key attractions will be bugs that glow under ultraviolet light, according to museum director Lynn Kimsey, professor of entomology at UC Davis.
Think scorpions. And don't forget that species of millipede found on Alcatraz Island. They glow, too!
