They go together like honey bees on bee balm and bumble bees on tomatoes.
When you attend the 102nd annual campuswide UC Davis Picnic Day on Saturday, April 16, be sure to head over to Briggs Hall, Kleiber Hall Drive, to see the Pollinator Pavilion, which will emphasize the importance of pollinators in both natural environments and food production.
"It is often said that one in every three bites of food we take is dependent on animal pollination," said Pavilion Pollinator coordinator Margaret "Rei" Scampavia, a doctoral candidate in entomology. "While there are some foods that do not rely on animal pollination, many of the tastiest and most nutritious food does. To this end, we have a series of posters demonstrating what a meal might look like with and without foods that benefit from animal pollination."
"We are going to have a series of exhibits showcasing pollinator diversity, demonstrating their importance in natural ecosystems and food production, and providing information on what members of the general public can do to help native pollinators," Scampavia said.
"We will have information on a wide variety of animal pollinators, including butterflies, flies, wasps, birds, and even bats. But the majority of the exhibit will focus on the most abundant pollinators: native bees."
The highlight is the walk-in Pollinator Pavillion, an enclosure where visitors can "safely view live pollinators, such as bees, butterflies and flies, up close and in person," the entomologist said. "Younger guests can practice scientific observation by filling out specially provided data sheets. Some of the species present will include: blue orchard bees, Monarch butterflies, Red Admiral butterflies, and Painted Lady butterflies."
Scampavia points out that the European honey bee "is the first thing many people think of when they hear the word pollinator. But in reality, this species is only one of tens of thousands of pollinator species; there are more than 20,000 species of bee besides the honeybee, for example. We hope that visitors to this exhibit will leave with a greater appreciation of the amazingly diverse animals that pollinate flowers."
Last year scores of enthusiastic visitors packed the Pollinator Pavilion. It proved to be one of the most popular, well-crafted, well-designed Picnic Day displays. Another eagerly anticipated event awaits Saturday.
And now there's an urgency.
"Many pollinator species are experiencing alarming declines," Scampavia said. "Monarch butterflies, for example, have declined by over 90 percent in the past ten years. To promote awareness of the plight of the Monarch, we have a series of exhibits with live caterpillars, chrysalises, and adults, which also contain important information about this species and what we can do to prevent further losses. There will also be information about ways to enhance outdoor spaces to promote and sustain healthy wild, native pollinators."

If you've ever wanted to learn how to tell the difference between a honey bee and a drone fly, head over to the Bohart Museum of Entomology, University of California, Davis, during the 102nd annual campuswide UC Davis Picnic Day on Saturday, April 16. The overall theme of Picnic Day is "Cultivating Your Authenticity." The Bohart Museum's theme: "Real Insects and Their Mimics."
The Bohart, located in Room 1124 of the Academic Surge Building on Crocker Lane, is ready for your questions. They'll be open from 10 a.m. to 3 p.m.
The drone fly (Eristalis tenax) or European hover fly, is about the same size as a honey bee (Apis mellifera) and has similar coloring. They both visit flowers and sip nectar. But the drone fly has what appears to be an "H" on its back. The "H" does not stand for honey bee--but don't tell the fly that!
What is a drone fly? In its immature (larva) stage, it's known as a rat-tailed maggot. It lives in drainage ditches, manure piles and puddled, polluted water. The honey bee larva does not live in drainage ditches, manure piles, and puddled, polluted water.
But what a great mimic the adult drone fly is--so great that's it's commonly mistaken for a honey bee. One of the most memorable cases of misidentification occurred on the cover of Bees of the World, by Christopher O'Toole and Anthony Raw. Someone--not them--selected a fly for the cover. Major metropolitan newspapers, nature magazines, stock photo agencies and bee fundraisers have all made the same mistake. Here's a honey bee. Nope, that would "bee" a fly.
A quick way to tell the difference between a honey bee and a drone fly:
Wings:
Honey Bee: Four
Drone Fly: Two
Antennae:
Honey Bee: Elbowed antennae
Drone fly: Short, stubby antennae
Flight:
Honey Bee: Moves pointedly to a flower; it does not hover
Drone Fly: Hovers and moves erratically
Sting:
Honey Bee: Workers (and queens) can sting
Drone Fly: Does not sting. Does not bite.
Bottom line: Don't apply the "Duck Test" to honey bees and drones ("If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck").
"If it looks like a bee, buzzes like a bee, and visits flowers like a bee, well, you know, it may not be a bee; it may be a fly."

What's a picnic without bugs?
Bugs may be uninvited guests at your family picnic, but at the campuswide UC Davis Picnic Day, set Saturday, April 16, bugs are not only invited, but more than welcome. And so are you, your family and friends. In fact, thousands will be attending the 102nd annual celebration, themed "Cultivating Your Authenticity."
The UC Davis Department of Entomology and Nematology is among the departments participating, with activities at Briggs Hall on Kleiber Hall Drive from 9:30 a.m. to 4 p.m., and an open house at the Bohart Museum of Entomology, located in Room 1124 of the Academic Surge Building on Crocker Lane, from 10 a.m. to 3 p.m.
Briggs Hall will be the site of a pollination pavillion, maggot art, cockroach races, fly-tying, face-painting, honey tasting, and a bee observation hive, and displays about ants, mosquitoes, aquatic insects and forest insects. The Bug Doctor booth ("The Doctor Is in") will be staffed by faculty and graduate students, while UC Davis forensic entomologist Robert Kimsey, aka "The Fly Man of Alcatraz," will man the Dr. Death table.
The UC Statewide Integrated Pest Management Program (UC IPM) will give away lady beetles, aka ladybugs, to kids to take home to their gardens. Lady beetles are beneficial insects and will make short work of your aphids. UC IPM also will provide advice on how to manage home and garden pests with environmentally sound methods.
At the pollinator pavilion, you can get up close and personal with butterflies, bees and other pollinators and learn how to protect our pollinators.
At the maggot art table, youths are invited to dip maggots into water-soluble paint and coax them to "create art" on a piece of white paper. Voila! Suitable for framing. And what a great conversation piece!
At the cockroach races, you are invited to cheer for your favorite roach. Everyone has a favorite roach, don't they?
You can also purchase a popular insect-themed t-shirt from the Entomology Graduate Student Association. Think beetles, bees, and wanna-bees.
Mosquitoes? They're invited, too. The Sacramento-Yolo Mosquito and Vector Control District will provide an educational exhibit about mosquito abatement.
Another popular exhibit at Briggs Hall is fly-tying by the Fly Fishers of Davis. They'll show you how to tie a fly.
At the Bohart Museum, the focus will be on "real insects as mimics." You'll see flies that look like bees--and bees that look like flies. In addition, you can hold and photograph the critters in the live "petting zoo," including Madagascar hissing cockroaches, walking sticks, and rose-haired tarantulas. The gift shop, featuring t-shirts, books, posters, insect collecting equipment, will be open.
All in all, it promises to be a picnic that will "bug ya." That's the plan!

You'd never know that if you looked in the backyard of UC Davis entomologists Robert and Lynn Kimsey.
The UC Davis Entomology Club, advised by Robert Kimsey, is building a 40-foot-long black widow spider for the UC Davis Picnic Day Parade on Saturday, April 18.
Latrodectus hesperus has never looked so...well...huge!
And so colorful--right down to the distinctive red hourglass.
What's it like seeing a huge spider coming to life in your backyard?
“Well, it is very weird!” said Robert Kimsey, a forensic entomologist and longtime advisor of the club. “It is huge and currently in pieces as it is getting its skin and pedipalps and other minor body parts and whatnot. It is anatomically correct in every way! The students have been trained well in arachnology!”
“There are legs all over the place,” Kimsey said. Each is slightly less than 20 feet long. "Again, it is huge. I have to admit that there are some brilliant artists and engineers in this group! But looking out the windows into the backyard takes your breath away. Any non-biologist would completely go to pieces.”
Along with anyone suffering from arachnophobia.
The last time the the UC Davis Entomology Club entered a float in the UC Davis Picnic Day Parade was about 20 years ago. And yes, it was a black widow spider (see photo below)
“The spider idea collectively came from all members of the cabinet after hearing about past picnic days from Bob,” said Entomology Club vice president Alex Nguyen. “When we presented it to the club we received very positive feedback so we decided to commit to marching in the parade with a float this year.”
The spider represents a month of planning and two weeks of building, Nguyen said.
During the parade, Entomology Club president Marko Marrero will be inside the spider, hoisting it up, and walking with it, along with two people at each leg.
If you want to see the spider, the opening ceremony of the parade begins at 9:25 a.m. in the grandstands on the North Quad Avenue across from Wickson Hall. The parade begins at 10, snakes downtown, and ends at noon. Announcement locations include the beginning of the parade; second and D Street in downtown Davis; F street in front of PDQ Fingerprinting; and third and C Street in downtown Davis.
You can also see the spider after the parade. It will be showcased in front of Briggs Hall, off Kleiber Hall Drive, where scores of entomological events will take place, including cockroach races, maggot art, honey tasting, and fly-tying. There will be a bee observation hive, ant displays, and displays of mosquitoes, forest insects and aquatic insects.
The UC Davis Entomology Club and the Entomology Graduate Student Association will be working the booths, along with faculty and staff.
Membership in the UC Davis Entomology Club is open to all interested persons (email entomologyclub@gmail.com). Members are faculty, staff, students (college and high school) and community residents.
They have at least one thing in common: they're interested in insects and other arthropods, including arachnids (spiders).
Even at picnics...and parades...

But when it comes to UC Davis Picnic Day 101, the "101" doesn't mean inexperience. This is the 101st annual celebration, which means UC Davis has been doing this for a century.
It's an event billed as entertaining, educational and informative--and it is. Plus, it's just plain fun!
Longtime friends and family get to hug ya. Entomologists get to bug ya. Visitors will see plenty of insects and other arthropods from 10 a.m. to 3 p.m. at two sites: Briggs Hall on Kleiber Hall Drive and the Bohart Museum of Entomology on Crocker Lane.
Theme of the campuswide picnic is “The Heart of Our Community,” but over at the Bohart Museum, the theme is “The Good, the Bad and the Bugly.” The museum, directed by Lynn Kimsey, professor of entomology at UC Davis, will feature pollinators. The museum houses nearly 8 million specimens. It also houses a live “petting zoo,” comprised of Madagascar hissing cockroaches, walking sticks and a rose-haired tarantula named Peaches, a crowd favorite.
At Briggs Hall, a new event is the Pollinator Pavilion, where visitors can see and learn about bees, butterflies and other pollinators. Pollination ecologist/graduate student Margaret “Rei” Scampavia is coordinating the project. “We're going to have painted lady butterflies, monarchs, male blue orchard bees, and a live bumblebee colony,” she said. Other events at the Pollinator Pavilion will include puppet shows, a chance to practice pollinator observations, museum specimens, and information on how individuals can help support healthy pollinator populations.
Forensic entomologist Robert Kimsey will portray “Dr. Death,” showing methods used in forensic entomology in 122 Briggs. The Phil Ward lab will assemble a display on the incredible diversity of ants. The Sharon Lawler lab will display aquatic insects and answer any questions about them.
Visitors can sample six different varietals of honey at a honey tasting table in the Briggs courtyard. The flavors are coffee blossom, meadowfoam blossom, buckwheat, creamed clover, cotton and chestnut, said Elina Niño, Extension apiculturist. A bee observation hive will be set up in across from the courtyard, where Niño and staff research associate Billy Synk will answer questions about bees.
Also at Briggs: graduate student Stacy Hishinuma and forest entomologist Steve Seybold, a chemical ecologist with the USDA Forest Service, Pacific Southwest Research Station, Davis, and an affiliate of the UC Davis Department of Entomology and Nematology, will display forest insects. Medical entomology graduate students will set up displays about diseases vectored by mosquitoes and other insects. The Sacramento-Yolo Mosquito and Vector Control District will provide an educational exhibit about mosquito abatement. Exhibits also will include such topics as fly fishing/fly-tying.
The UC Statewide Integrated Pest Management Program (UC IPM) will be giving away lady beetles, aka ladybugs, in front of Briggs Hall. They will answer questions about insects and display many of their books.
The Graduate Student Entomology Association (GMSA) and the Entomology Club will be out in force, coordinating and staffing the many insect activities. If you like bugs, you can buy an entomology t-shirt or have a bug painted on your face. The Bohart Museum also will be selling t-shirts and other items in its gift shop, which is open year-around.
If you're going to the parade, which starts at 9:30 a.m., be sure to check out the Entomology Club's float. It will not be an "itsy bitsy spider." It will be one ritsy gigantic spider! Following the parade, the float will be showcased in front of Briggs Hall.
What a day it promises to be...the good, the bad, and the bugly...
