Sure, they're known for donning butterfly, bee, and black widow spider costumes.
But sometimes they opt to characterize a scarecrow, a rag doll, a police officer, a pirate, Bernie Sanders and a hot dog. Or dress in a ghillie suit.
As a carved pumpkin spilled its guts, the costumes at the Bohart Museum of Entomology's Halloween party in the Academic Surge Building on Friday night, Oct. 27 startled, spooked and scared many of the Halloween celebrants.
Bohart Museum research entomologist Tom Zavortink portrayed Bernie Sanders, complete with a dark suit and tie and a name tag that read simply: "Bernie."
Bohart senior museum scientist Steve Heydon and his wife, Anita, chose to be a scarecrow and a black widow spider, respectively.
Forensic entomologist Robert Kimsey of the UC Davis Department of Entomology and Nematology Department faculty, wore a ghillie suit. Last year he carried a duck on his shoulder, an invited guest. This year he came duckless.
Students Parras McGrath posed as a tarantula hawk, Jamie Fong as a hot dog, Keely Davies as a police officer, Gabriela Rivera as a ragdoll, and Diego Rivera as a pirate with a faux parrot perched on his shoulder.
Staffer Tabatha Yang, the Bohart's outreach and public education coordinator, came as a "staff infection" with an appropriate mark on her cheek.
Shark teeth showed up, too. For the occasion, UC Davis entomologist alumnus (and artist) Danielle Wishon of the California Department of Food and Agriculture, detailed her face with gleaming predatory teeth, straight out of Jaws.
Bohart associate Greg Kareofelas, a dragonfly and butterfly expert, came as himself. "What are you supposed to be?" we inquired. "I'm Greg!" he said.
The attendees exchanged greetings, enjoyed food (catered by entomologists Ivana Li and Corwin Parker), dipped marshmallows, fruit and pretzels into a chocolate fountain, and broke a pinata. (See previous Bug Squad). They listened to a trio of musicians performing in front of the gift shop: James Heydon on guitar, Maia Lundy, vocals; and Maia's sister, Jade Lundy, on violin. Later Andre Poon, framed by a harp, entertained on the violin.
That's what entomologists do.
When Lynn Kimsey cut a chocolate anniversary cake, the predators, the prey, the police officer, the scarecrow, the hot dog and Bernie--and all the others--stepped forward.
You can have your cake and eat it, too, no matter if you're prey or predator or something else.
So said a little boy working on his maggot art project last Sunday afternoon, July 9, at the Bohart Museum of Entomology, UC Davis.
The occasion: a special open house with special presenters, members of North American Forensic Entomology Association (NAFEA). The forensic entomologists are on the UC Davis campus through July 12 for their annual conference. Forensic entomologist Robert Kimsey of the UC Davis Department of Entomology and Nematology, is a past president of the group.
Neel Fulde, 7, of Davis, arrived at the Bohart Museum with his mother, Shama Mesiwala, who watched him expertly use forceps to grab a maggot and dip it into non-toxic, water-based paint and release it on the "canvas"--white paper. Neel guided it around on what he termed his "obstacle-course" drawing.
His maggot, however, crawled too slow and he asked NAFEA member Royce Cumming of Salinas Valley for a "faster maggot."
Cumming said the maggot Fulde wanted was "taking a bath."
"In just a minute," Cumming said, and then handed Neel his forceps with "the faster" maggot attached.
Olivia Storms, 6, of Davis, arrived with her father, David Storms, and she, too, was eager to engage in maggot art. Cumming asked her: "Is the maggot the artist, or is it you, Olivia?" "Both," she said.
Forensic entomologist Rebecca O'Flaherty, a former graduate student of Kimsey's, coined the educational teaching curriculum, "Maggot Art," back in 2001 when she was studying at the University of Hawaii. She was rearing blowflies for her forensic research and wanted an activity to draw the interest of elementary school students. She also wanted to generate interest and respect for forensic entomology.
Maggot art is a traditional and popular activity at the annual campus UC Davis Picnic Day. The UC Davis Department of Entomology and Nematology conducts the event at Briggs Hall and will do so again at next year's Picnic Day: April 21.
Meanwhile, the Bohart Museum is gearing up for its next two summer open houses (free and open to the public and no reservations required):
Saturday, July 22, Moth Night from 8 to 11 p.m.: Moth Night, held in conjunction with National Moth Week, will enable visitors to explore nighttime nature through a blacklighting setup, enabling the collection of moths and other insects. The event takes place in the courtyard in back of the Bohart Museum. The museum will be open throughout Moth Night.
Sunday, Aug. 27: Bark Beetles and Trees, Forest Health in California, from 1 to 4 p.m.: The event is in collaboration with Steve Seybold, USDA Forest Service entomologist and an associate of the UC Davis Department of Entomology and Nematology. He and his students and staff will be there to show displays and answer questions.
The Bohart Museum, directed by Lynn Kimsey, professor of entomology at UC Davis, houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum.
Special attractions include a “live” petting zoo, featuring Madagascar hissing cockroaches, walking sticks and tarantulas. Visitors are invited to hold the insects and photograph them.
The museum's gift shop, open year around, includes 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.

If a picture is worth a thousand words, what is a bug worth?
That question was neither asked nor answered at the 103rd annual UC Davis Picnic Day, a campuswide open house, held April 22, but just about everything else was!
Let's take a look back at all the bug activities at Briggs Hall, home of the UC Davis Department of Entomology and Nematology. (We previously posted a UC Davis Picnic Day blog about the bugs at the department's Bohart Museum of Entomology).
Graduate student Brendon Boudinot, who is studying for his doctorate in entomology (working with major professor and ant specialist Philip Ward), chaired the Picnic Day Committee in between classes and ant research.
For some interesting alliteration, you could say "Brendon Boudinot's Bugs at Briggs."
Several thousand visitors climbed the Briggs Hall steps to
- cheer on the cockroach races (yes, cockroaches move fast!)
- participate in maggot art (dip a maggot into non-toxic, water-based paint and create a drawing. The term Maggot Art was coined by forensic entomologist Rebecca O'Flaherty, former UC Davis graduate student)
- watch fly-tying by the Fly Fishers of Davis
- observe the aquatic insects from the Sharon Lawler lab
- sample honey compiled by Extension apiculturist Elina Niño of the department's Harry H. Laidlaw Jr. Honey Bee Research Facility (this exhibit won a special award, determined by popular vote)
- explore the UC Statewide Integrated Pest Management Program tables (where the staffers displayed publications and gave away lady beetles, aka ladybugs)
- ask questions of The Bug Doctor (graduate student Ralph Washington Jr.); Dr. Death (forensic entomologist Robert Kimsey; the Nemotode Guy (Corwin Parker), and the Sacramento-Yolo Mosquito and Vector Control District (fight the bite)
- buy insect-themed t-shirts from the Entomology Graduate Students' Association (see website for sales)
- get their face painted by the UC Davis Entomology Club
- sample chocolate chirp cookies (think cricket!)
- greet ants (and uncles, too)
- pose as a cockroach, bee or fly behind the cutout boards
- marvel at the 40-foot-long black widow spider, which won the UC Davis Entomology Club the prize of "best float from an organization" at the UC Davis Picnic Day Parade
- take lots of selfies!
How many people trooped up the Briggs Hall steps? At least 3000.
How many bugs did they see? Hundreds and hundreds.
The cost? Free.
The memories? Priceless!
Sometimes it's found in a parade, where the "fear" turns to cheers and applause.
Take the case of the 40-foot black widow spider--yes, 40-foot spider!--that the UC Davis Entomology Club entered in the 103rd annual UC Davis Picnic Parade on Saturday, April 22.
The spider drew oohs and aahs from the crowd, and judges selected it the winner of the “Best Organization” category. It continued to draw oohs and aahs when the club showcased it in front of Briggs Hall on Picnic Day. Thousands of visitors stopped to look or capture photos with their families or take selfies. Little kids just stood and stared. "What's that, Mommy?"
What a spider! And complete with that distinguishing red hourglass marking.
“We built it three years ago,” related president Maia Lundy. “This year we just had to clean it up and make some modifications, like adding ventilation. It took us two meetings --or about 4 hours- of work this year. When we originally built it, we met several times over about a month to finish it. It's made out of plastic sheeting, chicken wire, pvc pipe, pool noodles, window screening, and held together by lots of duct tape and zip ties!”
The spider came to life in the backyard of entomologists Robert and Lynn Kimsey of the UC Davis Department of Entomology and Nematology faculty. Robert Kimsey, a forensic entomologist, serves as the club's advisor. Lynn directs the Bohart Museum of Entomology. Her specialty is wasps, but she answers all kinds of questions about insects and arachnids at the Bohart Museum.
The black widow spider is no stranger to the parade. It's reminiscent of the one that the UC Davis Entomology Club built for the parade about 25 years ago.
The Entomology Club decided to revive the project in 2015. It all took place in the Kimsey yard, and Robert Kimsey offered a blow-by-blow account then as he watched it develop from plastic sheeting to a black widow spider. “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 of the eight legs, each slightly less than 20 feet long. In real life, the body of the black widow spans about 1.5 inches long.
Kimsey said membership in the entomology club is open to all interested persons, including faculty, staff, college and high school students and community residents. (Contact firstname.lastname@example.org.) President Maia Lundy heads the club with Jamie Fong, vice president; Andre Poon, treasurer; Lovey Corniel, secretary; and Chloe Shott, vice secretary.
As for black widow spiders, yes, the bite is venomous. The glands contain the neurotoxin, latrotoxin, which causes the condition latrodectism, both named after the genus, according to Wikipedia. "The female black widow has unusually large venom glands and its bite can be particularly harmful to humans. However, despite the genus' notoriety, Latrodectus bites are rarely fatal. Only female bites are dangerous to humans."
Take a bow, UC Davis Entomology Club. Well done! The prize: a certificate and a glass trophy.
The black widow spider joined seven other parade award winners:
- Best Community Entry: Davis Whymcycle Society
- Most Spirited: DEVO (Davis Enology and Viticulture Organization)
- Best Theme: Biological and Agricultural Engineering
- Best Animal Entry: Canine Companions for Independence
- Best Department Entry: UC Davis School of Veterinary Medicine
- Best Organization: Entomology Club
- Parade Marshal's Choice: Bakuhatsu Taiko Dan
- Parade Participants' Choice: West Plainfield 4-H Club, Woodland
And it's an enemy to be reckoned with, Extension apiculturist Eric Mussen told students in the UC Davis "Biology of Parasitism" class, taught by forensic entomologist Robert Kimsey and nematologist Steve Nadler, Department of Entomology and Nematology.
Guest-lecturing at a special session held at the Harry H. Laidlaw Jr. Honey Bee Research Facility, UC Davis, Mussen talked about the varroa mite--its history, biology, damage and control methods--and then opened several hives at the apiary.
The Varroa destructor, a native of Asia, is now found in hives throughout the world except in Australia. It was first detected in the United States in 1987.
The eight-legged reddish-brown parasite, about 1–1.8 mm long and 1.5–2 mm wide, is a blood sucker that's difficult to control, Mussen said. Mites transmit viruses (there are now some 22 named RNA viruses) that can wipe out a hive. A familiar mite-transmitted disease that beekeepers see is DWV or Deformed Wing Virus. Mites are also known lowering the protein level of a bee's blood, and reducing its weight and life span.
Mussen said that mites spread from colony to colony by phoresy (animal-to-animal transport). They ride on flying drones (males) and adult worker bees (females). They also spread changing hosts on flowers.
"A mite enters a honey bee cell just before or during the time it is being capped," Mussen said. "It feeds on older larva or prepupa. Sixty hours later, the mite lays its first egg. The egg will hatch in about 24 hours."
"The number and release of offspring depend on the length of the pupal stage. The queen is pupa for 8.5 days (no mites). The worker is pupa for 12.5 days (1.3 mites) and the drone is pupa for 14.7 days (3 or 4 mites)," he said. Thus, due to the longer time required for drone development, drone pupae get the worst of it.
"When maturing, the newly emerged mites climb onto adult bees and feed by puncturing the intersegmental membranes and sucking the bee blood," Mussen related. "Often these are nurse bees that stay around the brood nest. Sometimes the hosts are drones and older foragers that are flying from the hive every day. Eventually the new mite climbs off the nurse bee onto a comb in the brood nest and enters a cell. The reproductive cycle starts and within 6 days, 44 percent of the young mites have moved into the brood cells; within 12 days, 69 percent of the mites are in the brood cells; and within 24 days, 90 percent of the mite are in the brood cells."
"If there is no brood, the mite has to feed on adult bee blood every six days or so to remain alive," Mussen said. "Mite life expectancy in summer is around 60 days; bees about 42 days. Mite life expectancy in the winter is up to 9 months; bees about six months."
Mussen also discussed how to detect mite infestations through non-chemical and chemical methods, and listed chemical treatments being used throughout the nation. Mites are developing resistance to a few chemical treatments, he pointed out. And, some of the chemical treatments not only kill the mites, but damage or kill the queen and the brood.
Beekeepers who try to go organic, figuring that "if the bees can't make it on their own--if they're not fit--let them die" are really doing a disservice to neighboring beekeepers, Mussen said. The mite will overrun a colony and then infest other colonies.
Public Enemy No. 1--definitely a force to be reckoned with.
