They are, you know, everywhere.
However, when the 103rd annual UC Davis Picnic Day takes place Saturday, April 22, you'll find them primarily at the UC Davis Department of Entomology and Nematology's exhibits at Briggs Hall and at the Bohart Museum of Entomology,
"Show Me the Honey" and "Show Me the Bugs."
Two of the department's exhibits are in the running for special awards at the campuswide Picnic Day. One is “Honey Tasting” at Briggs Hall, and the other is “Bigger, Better, Buglier: Impressive Science” at the Bohart Museum.
“Honey Tasting" will feature a selection of varietal honeys in a display that's the work of Extension apiculturist Elina Niño and colleagues at the Harry H. Laidlaw Jr. Honey Bee Facility.
"We will have the crowd favorites: coffee blossom, sweet meadowfoam, as well as some classics such as orange blossom and blackberry blossom and the 'love-it-or-hate-it' buckwheat honey," Niño said. "This year we will also be featuring our own 2016 crop of UC Davis honey from the apiculture program." The exhibit is one of six competing for awards in the category, "Hunger Fix.”
Overall, the UC Davis Picnic Day Committee selected 30 special exhibits to compete in five categories: "Best in Show," "Fun with Crafts," "Arts and Humanities," "Hunger Fix" and "Secrets of Nature," said UC Davis Picnic Day exhibits director Helen Xie.
The way it works: Picnic Day attendees vote for their favorite exhibits. Winning exhibits will be featured on social media pages such as Picnic Day website, Facebook, Twitter, Instagram, and Snapchat accounts after Picnic Day. They will also be featured next year, in preparation for Picnic Day 2018.
The poll will open beginning at 8 a.m. and close at 10 p.m. the same day.. All are welcome to vote at: https://orgsync.com/51524/forms/258052.
Last year the Department of Entomology and Nematology won two special awards. By popular vote, "Little Swimmers and Fly Tyers (Briggs Hall)," won the category, "Hidden Treasures," and "Real Insects and Mimics" (Bohart Museum) won the category "Family Friendly."
This year's Briggs Hall activities will be open from 10 a.m. to 4 p.m. The Bohart Museum of Entomology will swing open its doors from 10 a.m. to 3 p.m. Graduate student Brendon Boudinot is chairing the department's Picnic Day Committee. (See list of activities at Briggs Hall in previous Bug Squad blog.)
Boudinot's special favorite at the UC Davis Picnic Day? Ants. He's studying for his doctorate with ant specialist Phil Ward and is helping with the ant exhibit at Briggs Hall.
It wouldn't be a picnic without ants.
The UC Davis Bohart Museum of Entomology is again sponsoring two summer Bio Boot Camps: one for youths entering the seventh, eighth or ninth grade this fall, and one for youths entering grades 10 through 12 this fall.
"The camps focus on insect science and wildlife biology, due to our partnership with the UC Davis Museum of Wildlife and Fish Biology," said camp coordinator Tabatha Yang, the Bohart Musuem's education and outreach coordinator.
The Bio Boot Camp, the seventh annual camp for middle school students, will take place Monday-Friday, June 19-23. It's based in Davis, but Thursday night features an overnight stay at the UC Berkeley's Sagehen Field Station, near Truckee. The total cost, including meals and housing, is $425.
Bio Boot Camp 2.0, the fifth annual camp for high schoolers, is set July 23 to 29. They will spend one night at UC Berkeley's Quail Ridge Reserve, near Winters. "The next day will be spent exploring UC Davis and the museums," Yang said. "Then Monday night through Saturday morning, the camp is at the Sagehen Field Station where the youths will be developing mini research projects." The total cost, including meals and housing, is $795.
Pre-enrollments take place January through March, and the campers are selected for formal enrollment in early April. "We do this to select the most genuinely interested campers," Yang explained. The process is already under way: the first application came from Germany.
Enrollment is kept low to provide quality experiences. The middle-school camp is limited to 12 students and the high school camp, to 10. Each camp has two instructors. The Bohart Museum Society sponsors need-based partial scholarships for several campers each year.

Despite other major attractions--including the gorgeous spring day and the March Madness basketball tournament--nearly 300 people visited the UC Davis Bohart Museum of Entomology last Saturday during its three-hour open house, themed "Eggs to Wings: Backyard Butterfly Gardening."
They conferred with Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis; Robbin Thorp, distinguished emeritus professor of entomology; Tabatha Yang, education and outreach coordinator; and a number of Bohart associates, including entomologist Jeff Smith, who curates the moth and butterfly display; naturalist Greg Kareofelas, a butterfly and dragonfly enthusiast; entomologists Jessica Gillung and Ziad Khouri, doctoral candidates; Nicole Tam, junior specialist; and Joel Hernandez and Alex Nguyen, recent entomology graduates.
"Hungry, hungry caterpillars!" read one poster, illustrated with photos of the monarch, gulf fritillary and pipevine swallowtail caterpillars and their adult stages. "Having a garden full of flowers provides nectar, an important food source for adult butterflies, but what about their hungry, hungry caterpillars? It seems counterintuitive to grow plants that yu want insects to eat, but that is exactly what butterflies need when they are larvae."
Jeff Smith kept busy showing visitors the drawers of butterfly specimens, including blue morphos, monarchs and swallowtails. As he opened one drawer, he explained that "this drawer contains several species of South American rainforest butterflies, Preponas, in the genus Archaeoprepona." He described them as "extremely strong and fast fliers, but they love to settle on baits such as fermenting fruit on the ground. We (Bohart team) caught several in the ongoing Belize biodiversity work this past year."
Robbin Thorp showed live male Valley carpenter bees, Xylocopa varipuncta, green-eyed blond bees that are also known as "teddy bear" bees. "Boy bees can't sting," Thorp said, reassuring a few leary visitors. The female of the species is solid black. (Following the open house, Thorp returned the bees to the UC Davis Department of Entomology and Nematology's Häagen-Dazs Honey Bee Haven on Bee Biology Road.)
The bottle is tucked inside a zipped, meshed butterfly habitat and placed indoors or in a screened patio to prevent tachinid flies and wasps from laying their eggs in the caterpillars or chrysalids. Once the monarchs pupate and eclose, they are released to start another generation. This is a small-scale conservation project.
The Bohart Museum's regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. The museum is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free. Special open houses take place throughout the academic year. The next open house takes place during the annual campuswide Picnic Day on April 22.

Think "Monarch Starter Set."
And it's just in time for open house at the Bohart Museum of Entomology from 1 to 4 p.m., Sunday, March 19 in Room 1124 of the Academic Surge Building, Crocker Lane, University of California, Davis. The open house, themed “Eggs to Wings: Backyard Butterfly Gardening,” is free and open to the public. There you'll learn ideas on how to garden for butterflies and perhaps…you may go home with a Monarch Starter Set.
The Monarch Starter Set?
- Take one zippered, meshed butterfly habitat container, available for purchase from the Bohart Museum of Entomology's gift shop (or you can buy a zippered meshed laundry bag elsewhere)
- Add one Patrón tequila bottle, selected because it is a sturdy, chunky bottle with a broad base and a narrow neck.
- Fill bottle with water.
- Add milkweed plants (from your backyard or found in the wild)
- Add monarch caterpillars (from your backyard or found in the wild)
- Place in no-fly zone area, such as inside your house or on a screened porch. That's to deter tachinid flies and the wasps that lay their eggs inside the caterpillars and chrysalids and kill the hosts
- Watch a caterpillar eat its fill, form a chrysalis, and then observe the monarch eclose
- Release the monarch and voila! You're doing your part to help the declining monarch population
Using this method, we reared and released 64 monarchs last year in our small scale conservation project. What's good about the Patrón tequila bottle: the heavy bottle won't tip over, the caterpillars won't drown, and the milkweed will stay fresh. However, be sure to change the milkweed every day to keep the food fresh and abundant for your caterpillars.
Thanks to generous donations from TJ's Tavern on Main Street, Vacaville, the Bohart Museum can now provide the bottles to a limited number of "Monarch Moms" and "Monarch Dads." The butterfly habitats are available in its gift shop for around $20. The bottles are a gift. (Note: Teetotalism runs in our family so when I say "I'm going to the bar," that comment usually draws a raised eyebrow and a giggle or chuckle until I add "umm, to get the Patrón tequila bottle donations.")
The bottles are also perfect for the Bohart's live petting zoo and other uses at the insect museum.
Not to be overlooked is the bee logo--pollinators matter!--on each Patrón tequila bottle. The Patrón Spirits Company, which produces the product in Mexico, chose a bee as its logo "because of the well-known attraction bees have to Weber blue agave," according to Reference.com. "Weber blue agave is the primary plant from which Patrón tequila is made.” Tequila, as most folks know, is made from heart or core of the blue agave plant.
The primary pollinator of the blue agave, however, is the greater long-nosed bat or Mexican long-nosed bat, Leptonycteris nivalis. The lesser long-nosed bat (Leptonycteris curasoae) also is a key pollinator. Check out Purdue entomologist Gwen Pearson's informative piece on "Tequila, Booze and Bats" on wired.com. It includes a link to a video of bats pollinating agave. This is a favorite pollinator subject especially during National Pollinator Week, which this year is June 19-25.
Greg Kareofelas, a Bohart Museum of Entomology associate with expertise on local butterflies, will be at the Bohart Museum's open house on Sunday, March 19 from 1 to 4 p.m. to meet informally with visitors, talk about butterflies and answer their questions.
The open house, themed "Eggs to Wings: Backyard Butterfly Gardening," takes place in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis campus. It is free and open to the public. No reservations are required.
“I've always had an interest in butterflies since I was a little kid,” said Kareofleas, a Davis resident who has studied butterflies “seriously” since the late 1970s. "Back then, there was no Internet and books on butterflies in California were minimal and it seemed that most of the books published were on East Coast butterflies or butterflies out of our region. It was the late 1970s, after all, and we couldn't just go on the Internet for butterfly identification.”
It was then that Kareofelas met butterfly guru Arthur Shapiro, UC Davis distinguished professor of evolution and ecology. Shapiro, involved in butterfly research for more than four decades, now posts his work on his website.) Shapiro authored Field Guide to Butterflies of the San Francisco Bay and Sacramento Valley Regions (University of California Press, 2007).
Kareofelas, a naturalist and avid photographer, now spends much of his time researching and photographing butterflies, as well as dragonflies and other insects, and speaking to nature-oriented organizations. He is also a regular at the Bohart Museum open houses where he enthusiastically talks about insects he's encountered.
UC Davis offers great resources, Kareofelas says. “For instance, you can get an insect identified at the Bohart Museum, and a plant identified at the Herbarium. And then there are the great resources like the Sacramento Native Plant Society, the UC Davis Botanical Society and the UC Davis Arboretum and Public Garden."
Kareofelas is pleased to see the growing interest in butterflies and their larval host plants (where butterflies lay their eggs). “All you need is a yard to attract them,” he said. “Plant the larval host plants. Plant nectar plants, such as the butterfly bush, for the adults."
Want monarchs living in our backyard? “Plant milkweed, their larval host plant," Karofelas says.
Kareofelas mentioned a few host plants that will draw specific species:
- Plant pipevine, aka Dutchmen's pipe, for the Pipevine Swallowtails
- Plant passionflower vine for the Gulf Fritillaries
- Plant fennel for the Anise Swallowtails
- Plant baby tears (in the nettle family) for Red Admirals
- Plant snagdragons for Buckeyes
- Plant Rose of Sharon for the Gray Hairstreaks
- Plant mallow for the Checkered Skippers
Kareofelas has reared all the common species, as well some of the rare ones, including the California dogface butterfly, the state insect. With permission, he collected eggs from the rarely seen California dogface butterfly at its most populous breeding site, on Placer Land and Trust acreage near Auburn. The butterfly (Zerene eurydice) lays its eggs on false indigo (Amorpha californica).
Kareofelas, who serves as a guide several times a year for tours hosted by Placer Land and Trust, said that one result of rearing the California dogface butterfly is the publication of the 35-page children's book, "The Story of the Dogface Butterfly," written by Bohart associate Fran Keller (now an assistant professor at Folsom Lake College) with illustrations by then UC Davis student Laine Bauer, and photos by Kareofelas and Keller.
The book, available in the Bohart Museum's gift shop, tells the untold story of the California dogface butterfly, and how schoolchildren became involved in convincing the State Legislature to select the colorful butterfly as the state insect. (See Bug Squad.)
The Bohart Museum's open house on Sunday will showcase butterflies in the area. A family craft activity will be making "wiggling caterpillars," with straw and paper, said Tabatha Yang, education and outreach coordinator for the Bohart.
Directed by Lynn Kimsey, professor of entomology at UC Davis, the Bohart Museum is a world-renowned insect museum that houses a global collection of nearly eight million specimens. It also maintains a live “petting zoo,” featuring walking sticks, Madagascar hissing cockroaches and tarantulas. A gift shop, open year around, offers T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
The Bohart Museum's regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. The museum is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free. Special open houses take place throughout the academic year. The one on March 19 is the second to the last of the 2016-2017 academic year. The last one is Saturday, April 22, the campuswide UC Davis Picnic Day.
