In her professional life, she's an entomologist, researcher, teacher, mentor, artist, photographer, and author.
In her private life, she's a wife and mother.
Her specialty: darkling beetles. You'll often find her at her "home away from home," the Bohart Museum of Entomology where she studies with major professor Lynn Kimsey, Bohart Museum director and UC Davis professor of entomology.
Fran Keller is the designer and impetus behind the many Bohart Museum of Entomology posters and t-shirts. Posters include Butterflies of Central California, Dragonflies of California, California State Insect (California Dogface Butterfly) and Pacific Invasive Ants. T-shirts spotlight dragonflies, butterflies and walking sticks. (Access them at the Bohart's online gift shop.)
Fran Keller also found time to author a children's book on the California dogface butterfly, with sales benefitting the Bohart Museum.
If you belong to the Entomological Society of America (ESA) or another entomological organization, you've probably seen her leading symposiums, presenting talks, and conferring with other scientists.
There's not much that she CAN'T do.
So, on Wednesday, Fran Keller will probably convince her audience that darkling beetles are more exciting than any other insect. After all, her enthusiasm is well known and led to her UC Davis honor as an outstanding teacher.
Keller's exit seminar, "Taxonomy of Stenomorpha Solier, 1836 (Coleoptera: Tenebrionidae: Asidini," will be from 12:05 to 1 p.m., Wednesday, May 29 in Room 1022 of the Life Sciences Addition, located on the corner of Hutchison and Kleiber Hall drives. Plans call for the seminar to be videotaped for later public viewing on UCTV.
“My research focuses on a very large genus which historically had 88 species and no modern species level work for several taxa for nearly 175 years,” Keller said. “Part of my research focuses on a group of flightless species restricted to the Sierra Transvolcanica or southern Transverse range in Mexico. Using biogeography, morphological analyses and the examination of over 10,500 specimens, I recognize 51 valid species of Stenomorpha Solier, 1836, with seven newly recognized subgenera, while 37 formerly recognized species are synonymized or newly combined."
“Certain Stenomorpha species occur in California vernal pools but are not listed as vernal pool species,” Keller said. She also will discuss the importance of taxonomy in conservation.
If time allows, Keller will discuss her other projects, working in the Bahamas and mentoring students, as well as her recent research on morphology and developmental patterns of gene expression.
Keller received her associate science degree in biology and chemistry, with highest honors, from Sacramento City College in 2001 and then transferred to UC Davis where she received her bachelor’s degree in evolution and ecology (2004), and her master’s degree in entomology (2007).
She served as a teaching assistant for a number of courses at UC Davis and has also presented guest lectures, including “Insect Sex and Mating Systems” and “Insects and the Environment—Ecological Physiology.”
Among her many awards at UC Davis:
- Outstanding Graduate Student Teaching Award, May 2008
- Division of Biological Sciences (DBS) Commencement Speaker, June 2004
- DBS Departmental Citation for Outstanding Achievement in Academics and Research in Evolution and Ecology, Spring 2004
- Outstanding Senior, 2004
- Undergraduate Research Conference, Oral Presentation, April 2004
- President’s Undergraduate Fellowship, Spring 2003
Her students applaud her teaching skills, her enthusiasm, and her care and concern. Said one student: "It's reassuring to know that out of a maze of 30,000 students and faculty at Davis that there are people like Fran who really care."
Bees carry pollen in their pollen baskets, but that's not the only place.
"Pollen grains adhere to the bee's hairs, influenced by opposite electrical charges," writes Norman Gary, emeritus professor of entomology at the University of California, Davis, in his popular book, Honey Bee Hobbyist: The Care and Keeping of Bees.
Bees comb and brush the pollen into their pollen baskets but, as Gary writes, "Fortunately for the plants, bees aren't 100 percent efficient at transferring the pollen to the pollen baskets. Thousands of pollen grains may still remain on their bodies even after they finish grooming. Bees leave enough pollen behind, depositing it accidentally on female flower structures to ensure effective pollination."
Honey bees collect nectar, pollen, propolis (plant resin) and water to keep the colony humming. Nectar is the colony's carbohydrate (sugar) while pollen is the protein. Pollen also contains such nutrients as minerals, vitamins and fatty substances.
"During an entire year, a typical bee colony gathers and consumes about 77 pounds of pollen," Gary writes, adding that a single pollen-foraging bee will average 10 trips per day. "When pollen is abundant, a bee can gather a full load in as little as ten minutes by visiting several dozen flowers," he points out.
If you look closely, sometimes you'll see a bee covered with pollen. The bee below was on a yellow coneflower (Echinacea paradoxa) in Napa.
If you're allergic to pollen, these photos just might make you sneeze!
Tabatha Yang and her six-month-old son, Karoo, were sitting on their lawn last Sunday at their West Davis home, when she saw red. Literally.
One minute they were enjoying the springlike weather, and the next minute his head was covered with bright red dots. Looking closer, she spotted a tiny insect in his eye, which she quickly removed.
Then her legs began to welt and itch.
They had just encountered no-see-ums, tiny Valley Black Gnats that feed on blood.
“The adults are emerging in large numbers now and need blood so residents need to beware of grassy areas that cover alkaline clay soils,” said Lynn Kimsey, director of the Bohart Museum of Entomology and professor entomology at UC Davis. “These insects are ferocious biters. Even though they don't spread any diseases, they are sufficiently annoying to keep people indoors in some areas of California.”
The Bohart Museum is now fielding scores of calls and emails.
“These no-see-ums are smaller than fleas and have a supreme itch,” said Yang, Bohart Museum education and outreach coordinator, who knew immediately what they were.
The biting gnats are particularly troublesome along the west side of the Sacramento Valley, including Davis and Woodland. “They're often in grassy areas, such as in parks and on golf courses on the west side of California's Central Valley,” Kimsey said. “When the soil begins to dry and cracks develop, the adults emerge.” The complete life cycle from egg to adult takes about two years.
The no-see-ums (Leptoconops torrens) belong to the family Ceratopogonidae and are about 1/16-inch long. They are so tiny they could pass through window screens, but they don't, Kimsey said. However, they can and do slip beneath loose clothing, unnoticed, to get a blood meal.
Like mosquitoes, only the female no-see-ums bite. The insects breed when the weather warms in the spring, usually in May and June, and they remain a pest for several weeks, Kimsey said. They need a blood meal to complete their reproductive cycle.
They also bite domestic and wild animals and birds.
The females inject saliva into the skin, which pools the blood just beneath the surface, resulting in a small red dot that becomes excruciatingly itchy. A single bite can welt into a one-or two-inch diameter spot, which lasts about two weeks.
Kimsey cautions people not to scratch the welts, as scratching makes the itchy bites last twice as long and can lead to infected sores.
To avoid being bitten, Kimsey recommends that you limit exposure by not sitting long in places where they are likely to occur, or where you've heard of problem areas. “Move quickly through the area.”
“Repellents,” she added, “aren't effective against these flies.”

What a match--honey bees and pomegranate blossoms.
Watching the golden bees forage amid the brilliant red blossoms in the late afternoon is a delight to see, especially when the sun backlights them.
The ancient fruit, native to Iran, is one of the world's first cultivated fruits. Thankfully, it is now "trendy" in California, with some 30,000 acres of pomegranates in production. We treasure its ruby-red kernels, tart flavor, and high antioxidant content. Since ancient times, the fruit has symbolized health and fertility. It's been said that Adam and Eve weren't tempted by an apple in the Garden of Eden, but by a pomegranate. In Egypt, the pomegranate was known as "The Fruit of Kings."
Spanish settlers introduced the pomegranate tree to California in 1769. The honey bees came later: 1853.
But when you think about it, honey bees and pomegranates have been together for millions of years--just not in California.
The pomegranate tree in our yard is 86 years old and has seen generations of bees come and go.
A promenade in the pomegranates...
A spider web is one of nature's most marvelous wonders. It's art, it's architecture, and it's engineering.
The silk is as beautiful as it is deceiving. It's 10 times stronger than Kevlar; as sticky as cotton candy covered with honey; and as flexible as a classical ballet dancer.
It's also a restaurant of sorts when the sticky strands nab unsuspecting prey. Unlike humans sitting down at a restaurant to order a meal from the menu, a spider never knows what's on the menu until it "magically" appears. It could be a honey bee, sweat bee, carpenter bee, spotted cucumber beetle, ladybug, lacewing, crane fly, another spider or some other critter.
We saw this newly woven wheel web on our front porch this morning. As the sun rose, the web glowed, glistened and glittered. An orbweaver at work..setting the dinner table...
The intricate web made us think of E. B. White's children's novel, "Charlotte's Web." Charlotte, a barn spider, kept writing messages such as "Some Pig" to try to save the life of a pig named Wilbur.
The farmer got the message, but in the real world, the spider's message is not about saving a life, but entrapment.
