UC Davis Picnic Day is Saturday, April 23.

The 108th annual UC Davis Picnic Day will include scores of insect-related displays and activities sponsored by the UC Davis Department of Entomology and Nematology.  Entomological events will take place at Briggs Hall;  the Bohart Museum of Entomology  (Academic Surge Building on Crocker Lane); and in the courtyard of Green Hall (formerly Life Sciences). 

Free and open to the public (as is parking), it will be the first in-person Picnic Day in nearly three years. The theme is "Rediscovering Tomorrow."

Danielle Rutkowski, doctoral candidate in the lab of associate professor Rachel Vannette, is planning and coordinating the UC Davis Graduate Student Association (EGSA) events.

"We're all so excited that it's in-person again," said Jill Oberski, EGSA president. "Grad students usually run most of the entomology exhibits, but most of the younger graduate students have never been to a 'real' Picnic Day—so we finally have the chance to pass the experience on to them. It's always crazy and exhausting but it's so much fun, and a really great opportunity to engage with the public."

EGSA will be selling a number of t-shirts, both classic attire and new designs. New designs are "UCD Amblypygid," designed by Emma Jochim of the Jason Bond lab (it's EGSA's first arachnid shirt) and the limited-edition 'Mosquito Picnic' for Picnic Day 2022, designed by Oberski. "And we have stickers, masks, and several years' worth of back stock we would love to sell!" Oberski noted, adding that EGSA takes both cash and credit cards. Some of the classic T-shirt designs, such as The Beetles, sell fast. The link to EGSA's online store: https://ucdavisentgrad.square.site/

Entomological offerings will be showcased at the 107th annual UC Davis Picnic Day, themed "Discovering Silver Linings," to take place virtually on Saturday, April 17.

Silver linings promise to grace this family-oriented event, billed as informative, educational and entertaining. 

Picnic Day officials have released the schedule of events that includes entomological exhibits and talks from the UC Davis Department of Entomology and Nematology, Bohart Museum of Entomology and the UC Davis Graduate Student Association. 

Here's a quick list: 

Bohart Museum of Entomology

Bohart associate Greg Kareofelas, Bohart Museum associate and naturalist, has created a pre-recorded video on the Gulf Fritillary butterfly, Agraulis vanillae. These orange-reddish butterflies have  silver-spangled underwings, are glorious. Kareofelas will showcase them and show you how to rear them, which is what he did last year during the pandemic. It's on YouTube at https://www.youtube.com/watch?v=OR3WwE7mbrA.   

Entomologist Jeff Smith, the volunteer curator of the Lepidoptera collection at the Bohart, will present a live Zoom event from 1 to 2 p.m. on Saturday on mimicry in Lepidoptera (moths and butterflies). "I will briefly mention camouflage," Smith says, "and spend most of the time on mimicry for defense--mimics of toxic or distasteful species, mimicry using odors or sounds, mimics of snakes or spiders, and mimics of non-food materials such as bird feces."

Zoom Meeting ID: 928 4120 3978 
Zoom Passcode: 160485

"People who want to submit their questions to Jeff or request to see certain species from the collection can email their requests to bmuseum@ucdavis.edu with Picnic Day in the subject," says Tabatha Yang, the Bohart Museum's education and outreach coordinator. "We won't have the time or capacity to access the collection during the event for any requests. Instead, we will pull the items that are requested or relevant to the talk and have those prepared to show. Of course we may not be able to honor everyone's request, but we will do our best."

The Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane (the museum is closed now due to the pandemic), is directed by Lynn Kimsey, UC Davis professor of entomology. It houses nearly eight million insect specimens, plus a year-around gift shop and a live "petting zoo," comprised of Madagascar hissing cockroaches, stick insects and tarantulas.

The UC Davis Department of Entomology and Nematology and the Bohart Museum of Entomology will be participating in the virtual 107th annual UC Davis Picnic Day on Saturday, April 17, a traditional event being held untraditionally this year due to the COVID-19 pandemic. 

The entomological events will include cockroach racing and a series of talks. Among them: Bohart Museum associate and natural historian Greg Kareofelas will present a pre-recorded video on Gulf Fritillary butterflies and entomologist Jeff Smith,  the  Bohart's volunteer curator of the Lepidoptera collection, will deliver a live Zoom talk on  butterfly and moth mimicry from 1 to 2 p.m. 

Said Smith: "For my presentation on mimicry within Lepidoptera, it will briefly mention camouflage and spend most of the time on mimicry for defense-- mimics of toxic or distasteful species, mimicry using odors or sounds, mimics of snakes or spiders, and mimics of non-food materials such as bird feces."

More events--and the schedule--are pending.

The Bohart Museum, temporarily closed, is located in Room 1124 of the Academic Surge Building on Crocker Lane. Directed by Professor Lynn Kimsey, the Bohart Museum includes nearly eight million insect specimens, a live "petting zoo" (Madagascar hissing cockroaches, stick insects and tarantulas) and an online gift shop stocked with insect-themed t-shirts, jewelry, hoodies, books, posters and more.

Discovering Silver Linings
This year's theme is “Discovering Silver Linings.” Despite all that has happened this year, the UC Davis community has continued to find silver linings everywhere, the Picnic Day officials reported on their website. "Our campus always strives to inspire hope and works towards a better and brighter tomorrow."

Last year's in-person events also were canceled and some virtual events took place.

"This long-standing campus tradition began in 1909 when the University Farm invited the surrounding community to view their new dairy barn. Two thousand visitors attended, bringing picnics to complement the coffee, cream, and sugar provided by the University. Following the success of the 1909 picnic, the faculty of the University Farm continued to plan and sponsor the event until a student committee took over the task in 1912. Through the years of Picnic Day history, the event has only been canceled five times. In 1924, an outbreak of hoof-and-mouth disease among the cowherds caused the first cancellation. In 1938, delayed construction of the gymnasium, which was needed to accommodate the ever-increasing number of participants, led to a second cancellation. During World War II, the Army Signal Corps controlled the campus, and Picnic Day disappeared from 1943 to 1945. Since 1946, Picnic Day has been growing strong and now boasts an annual attendance of more than 70,000 people. This year, there will be more than 200 events on campus and an estimated 75,000 visitors attending this special event. Since 1959, the parade was extended to include downtown Davis to celebrate the fact that Davis became a separate UC campus and not just the Farm School for UC Berkeley."

And what's the canceled 105th annual UC Davis Picnic without virtual insects?

The Department of Entomology and Nematology annually hosts dozens of insect-themed Picnic Day events at Briggs Hall and at the Bohart Museum of Entomology. But this year, the insects went virtual due to the coronavirus pandemic precautions.

The campuswide Picnic Day Committee hosted a virtual tour of some of the planned events, and posted this link: https://picnicday.ucdavis.edu/virtual/

The spotlight paused on the Bohart Museum, which houses nearly eight million insect specimens; the seventh largest insect collection in North America; the California Insect Survey, a storehouse of the insect biodiversity; and a live “petting zoo” comprised of Madagascar hissing cockroaches, walking sticks, tarantulas and the like. It also is the home of a gift shop, stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.

Directed by UC Davis entomology professor Lynn Kimsey for 30 years, the museum is named for noted entomologist Richard Bohart (1913-2007). The Bohart team includes senior museum scientist Steve Heydon; Tabatha Yang, education and outreach coordinator; and entomologist Jeff Smith, who curates the Lepidoptera (butterflies and moths section).

If you browse the Bohart Museum site, you'll find fact sheets about insects, written by Professor Kimsey.

But if you want to see the Bohart Museum's virtual tours, be sure to watch these videos:

• Director Lynn Kimsey giving a Bohart Museum introduction
• Tabatha Yang, education and outreach coordinator, presenting an arthropod virtual tour
• Diane Ullman, professor of entomology and former chair of the department, presenting a view of the Lepidodpera section.

Professor Rick Karban is featured in a TED-Ed talk on plant communication.

Also on the UC Davis Virtual Picnic Day site, you'll learn “How to Make an Insect Collection," thanks to project coordinator James R. Carey, distinguished professor, UC Davis Department of Entomology and Nematology; and "Can Plants Talk to Each Other?" a TED-Ed Talk featuring the work of ecologist Rick Karban, professor, UC Davis Department of Entomology and Nematology.

"Female tsetse flies carry their young in an adapted uterus for the entirety of their immature development and provide their complete nutritional requirements via the synthesis and secretion of a milk like substance," he says. PBS featured his work in its Deep Look video, “A Tsetse Fly Births One Enormous Milk-Fed Baby,” released Jan. 28, 2020. (See its accompanying news story.) 

PBS also collaborated with the Attardo lab and the Chris Barker lab, UC Davis School of Veterinary Medicine, for a PBS Deep Look video on Aedes aegypti, the mosquito that transmits dengue fever and Zika. The eggs are hardy; "they can dry out, but remain alive for months, waiting for a little water so they can hatch into squiggly larvae," according to the introduction.  Watch the video, "This Dangerous Mosquito Lays Her Armored Eggs--in Your House."

In the meantime, the UC Davis Picnic Day leaders are gearing up for the 106th annual, set for April 17, 2021. What's a picnic without insects?
