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."

It shouldn't be, nor is it, at the University of California, Davis.
Medical entomologists and other scientists at UC Davis are planning a Malaria Awareness Day from 10 a.m. to 1:30 p.m. on Monday, April 25 in the Memorial Union.
The event will take place in MU II (second floor) and is free and open to the public.
Statistics from the Center for Disease Control and Prevention (CDC) tell the alarming story.
"It is a leading cause of death and disease in many developing countries, where young children and pregnant women are the groups most affected," the CDC points out, citing these figures from the World Health Organization's World Malaria Report 2013 and the Global Malaria Action Plan:
- 3.4 billion people (half the world's population) live in areas at risk of malaria transmission in 106 countries and territories
- In 2012, malaria caused an estimated 207 million clinical episodes, and 627,000 deaths. An estimated 91% of deaths in 2010 were in the African Region.
The most vulnerable groups, CDC says, are young children, who have not yet developed partial immunity to malaria; pregnant woman, whose immunity is decreased by pregnancy, especially during the first and second pregnancies; and travelers or migrants coming from areas with little or no malaria transmission, who lack immunity.
Africa, according to CDC, is the most affected due to a combination of factors:
- A very efficient mosquito (Anopheles gambiae complex) is responsible for high transmission.
- The predominant parasite species is Plasmodium falciparum, which is the species that is most likely to cause severe malaria and death.
- Local weather conditions often allow transmission to occur year round.
- Scarce resources and socio-economic instability have hindered efficient malaria control activities.
The schedule for the UC Davis Malaria Awareness Day:
10 to 10:30 am.: Coffee/social/posters
10:30 to 10:50: "General Malaria Biology" by medical entomologist Gregory Lanzaro, professor, Department of Pathology, Microbiology and Immunology, UC Davis School of Veterinary Medicine.
10:50 to 11:20: Conducting Field Research in Rural Africa" by medical entomologist Anthony Cornel, associate professor, UC Davis Department of Entomology and Nematology and based at the UC Kearney Agriculture and Research Center, Parlier
11:10 to 11:30: "Marlaria Parasites in the Mosquito" by molecular biologist Shirley Luckhart, professor, UC Davis Department of Medical Microbiology and Immunology and an adjunct professor in the Department of Entomology and Nematology
11:30 to 11:50: "Mosquito-Borne Viral Diseases" by medical entomologist Chris Barker, assistant adjunct professor and assistant research scientist, UC Davis Department of Pathology, Microbiology and Immunology
11:50 to 12:10: "Disease Transmission by Non-Mosquito Vectors" by epidemiologist/veterinarian and disease ecologist Janet Foley, professor, UC Davis Department of Medicine and Epidemiology
12:10 to 1:30: A free lunch will be provided, but reservations must be made by April 21 to ykyamasaki@ucdavis.edu.

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!

Clean-shaven it's not. Yet it's a cut above.
For bees, syrphids and butterflies, the long-blooming Jupiter's Beard make the cut.
Centranthus ruber, also known as Jupiter's Beard, Red Valerian, Kiss-Me-Quick, and Keys to Heaven, is a popular drought-tolerant plant that attracts insects like a picnic draws people.
A native of the Mediterranean region, Jupiter's Beard grows wild in California and in several other states, including Arizona, Hawaii, Oregon and Utah.
Cozy up to a Jupiter's Beard, and you're likely to see foraging honey bees, native bees, syrphid flies and butterflies. (And assorted other critters like leafhoppers, lady beetles and spiders.)
The plant was one of the first residents of the Häagen-Dazs Honey Bee Haven, a half-acre bee friendly garden on Bee Biology Road, UC Davis. The garden, installed in the fall of 2009 and operated by the UC Davis Department of Entomology and Nematology, will be the site of a spring open house from 11 a.m. to 2 p.m. on Saturday, April 9. The event, free and open to the public, will feature a noon tour, and other activities, including how to catch, observe and release bees; how to identify bees; and what to plant to attract bees and other pollinators. A bee observation hive is also planned where visitors can see the queen bee, workers and drones.
Then don't forget the campuswide UC Davis Picnic Day on Saturday, April 16. What's a picnic without bugs?
In addition to the scores of the other fun and educational activities on campus, remember the two B's: Briggs and Bohart. You can enjoy entomological events at Briggs Hall, located on Kleiber Hall Drive, and the Bohart Museum of Entomology, located on Crocker Lane.
Among the activities at Briggs: cockroach races, pollinator pavilion, a honey tasting, fly-tying, facepainting, Bug Doctor (The Doctor Is In!), maggot art, medical entomology exhibits, and displays of ants, mosquitoes, aquatic insects and forest insects. The UC Integrated Pest Management Program will give away lady beetles (aka ladybugs) to kids, and hand out information about pests and beneficial insects.
At the Bohart Museum, home of nearly eight million insect specimens, you can get up close and personal with the live "petting zoo," including the Madagascar hissing cockroaches, walking sticks and a rose-haired tarantula named "Peaches." In keeping with the UC Davis Picnic Day's overall theme, "Cultivating Our Authenticity," the Bohart theme is "Real Insects and Their Mimics." Think bees. Think flies. Think about how to tell the difference. Syrphids, especially drone flies, are commonly mistaken for honey bees. Not all floral visitors are bees...
