When you're 5 years old, the world is full of wonders.

Especially when your mother takes you to the Bohart Museum of Entomology to see the butterfly specimens.

Such was the case when Cash Belden, 5, and his mother, Michelle Belden (she's the coordinator of the campus Aggie Surplus, formerly the Bargain Barn) attended the Bohart Museum open house during the eighth annual campuswide UC Davis Biodiversity Museum Day.

Little Cash especially liked the monarchs and the blue morphos.

Entomologist Jeff Smith, who curates the butterfly/moth section at the Bohart, showed them around. He estimates the Bohart has half a million Lepitoptera in the collection, about 60 percent moths and 40 percent butterflies.

He mentioned the "defensive strategies these insects use for survival, such as camouflage, warning coloration, mimicry of other species."

"We love to teach about the importance of Lepidoptera in the environment, either to their habitat directly or possibly as an indicator of the health of their habitat."

And, of course, there's the beauty of the insects.

Next time it's spiders!

The next open house, themed "Eight-Legged Wonders" and featuring spiders, is set from 1 to 4 p.m., Saturday, March 9. in Room 1124 of the Academic Surge Building on Crocker Lane. It's free and family friendly. Professor Jason Bond, the Evert and Marion Schlinger Endowed Chair in Insect Systematics in the UC Davis Department of Entomology and Nematology, will host a slide show at 1 p.m.  Visitors will see specimens and can engage in interactive activities and family arts and crafts.

The Bohart Museum, home of a global collection nearly eight million specimens, is directed by Lynn Kimsey, professor of entomology at UC Davis. 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 and on major holidays. Admission is free. Open houses, focusing on specific themes, are held on weekends throughout the academic year. More information on the Bohart Museum is available by contacting (530) 752-0493 or Tabatha Yang, education and public outreach coordinator at tabyang@ucdavis.edu.

Identification. Collaboration. Camaraderie.

The scientists and butterfly/moth enthusiasts who gathered Saturday, Feb. 9 for the Northern California Lepidoptera  Society meeting in the Bohart Museum of Entomology at the University of California, Davis, did all that: identify specimens and engage in collaboration and camaraderie.

They ranged from those early in their career, to mid-point, to the height of their career, to retired.

The group meets for a mid-winter gathering once a year, alternating between the Bohart Museum of Entomology at UC Davis and the Essig Museum of Entomology at UC Berkeley.

Senior museum scientist Steve Heydon, Bohart associate John "Moth Man" DeBenedictis; and Jeff Smith, curator of the butterfly/moth section at the Bohart hosted the event, assisted by Lynn Kimsey, director of the Bohart Museum and Bohart associate and naturalist Greg Kareofelas. 

In their meeting notice, Heydon, DeBenedictis and Smith noted that those attending could bring specimens, photos, PowerPoint presentations "or slides from collecting trips and tales of collecting triumphs to share with others
and that "attending lepidopterists may be able to help you identify specimens and the museum collection will be open for yoour inspection."

Christopher Jason, a recent UC Davis graduate in environmental science, was there with his collection. In March he will head to Washington State University, the Vancouver, campus, to work as a technician in the lab of conservation biologist/associate professor Cheryl Schultz, who researches at-risk butterflies in Pacific Northwest Prariries. Or, as Schultz. writes on her website: "Human-caused changes in the earth's ecosystems are responsible for the decline and extinction of the world's biological diversity. In the Conservation Biology Research Group, we study the ecology of at-risk species in response to key drivers: habitat loss, habitat fragmentation, habitat degradation, invasive species, alteration of ecosystem process, and global climate change. Using a population-ecology lens, we use field and quantitative methods to address pivotal ecological questions. We seek to understand the relative contributions of individual, population and landscape-level processes to the population viability of endangered species as these processes interface with realistic conservation interventions. Our work largely uses at-risk butterflies in Pacific Northwest Prairies as a model system to address fundamental ecological questions while simultaneously tackling focal questions to guide on-the-ground practice."

Retired public health entomologist and Bohart associate Dick Meyer of Bakersfield, known as "the mosquito guy," was there. He recently retired as assistant manager of the Orange County Vector Control Agency. He did not bring any of his collection, but he did tell us that he has 225 drawers of insects at home, including 71 drawers of butterflies. "Did you know that the highest diversity of butterflies in the country is in Kern County?" he asked. Meyer, who holds a doctorate in entomology, studied with major professor Richard M. Bohart Jr., for whom the Bohart Museum is named.

Among those participating:

• Bohart associate Jerry Powell, emeritus director of the Essig Museum, and co-author of California Insects.
• Marc Epstein, senior insect biosystematist for the California Department of Food and Agriculture and author of the book, Moths, Myths and Mosquitoes: the Eccentric life of Harrison G. Dyer Jr.
• Kelly Richers, treasurer of the Lepitopterists Society and an affiliate of Essig Museum of Entomology who is also  afield associate with the Los Angeles County Museum of Natural History and member of board of directors of the Wedge Entomological Research Foundation
• Lawrence "Larry" Allen of Calaveras County, author of A Field Guide to the West Coast Butterflies of the United States, one of the books available in the Bohart Museum's gift shop (he donated all sales of his book that day to the Bohart).
• Arthur Shapiro, UC Davis distinguished professor of evolution and ecology and author of Field Guide to Butterflies of the San Francisco Bay Area and Sacramento Valley Regions.
• Entomologist Rick Kelson, who directs the butterfly habitat at Six Flags Discovery Kingdom, Vallejo
• Bohart associate Bill Patterson, former graduate student of Richard Bohart
• Rosser Garrison, research associate with the California State Collection of Arthropods, retired senior insect biosystematist, California Department of Food and Agriculture, and co-author of Dragonfly Genera of the New World: An Illustrated and Annotated Key to the Anisoptera
• Don Miller, professor at Chico State University who teaches entomology in the Department of Biological Sciences
• Ryan Hill, professor at University of Pacific, Stockton
• Chris Tenney,  retired educator from Pacific Grove
• Jeffrey Caldwell, known for his ecological restoration
• John Lane, one of first graduate students of Art Shapiro (Lane received his master's degree)
• Paul Johnson, biologist with the National Parks Service
• Hobbyist Jeff Baier of Napa
• Physician Val Albu of Fresno
• And many more...

At the last gathering in the Bohart, Kelly Richers, who compiles the California Moth Specimen Database, maintained at the Essig Museum since 1996 as a resource to better survey and understand California moths, said of the systematists:  "We're a dying breed." 

This year self-described "aspiring entomologist" Madison Cunha of Modesto attended with her mother, Christine Cunha. True to her love of insects, Madison wore a dress adorned with a beetle pattern.

Scientists say that 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies.

"The Lepidoptera are among the most successful groups of insects. They are found on all continents, except Antarctica, and inhabit all terrestrial habitats ranging from desert to rainforest, from lowland grasslands to mountain plateaus, but almost always associated with higher plants, especially angiosperms (flowering plants). Among the most northern dwelling species of butterflies and moths is the Arctic Apollo (Parnassius arcticus), which is found in the Arctic Circle in northeastern Yakutia, at an altitude of 1500 m above sea level. In the Himalayas, various Apollo species such as Parnassius epaphus have been recorded to occur up to an altitude of 6,000 miles above sea level."--Wikipedia.

Oh, the butterflies you'll see at the Bohart Museum of Entomology during the eighth annual UC Davis Biodiversity Museum Day on Saturday, Feb. 16.

Entomologist Jeff Smith, who curates the Lepidoptera (butterflies and moths) collection, says "I believe we have half a million Lepitoptera in our collection, and it is likely 60 percent moths and 40 percent butterflies."

What can visitors expect to see at the Bohart Museum during the four-hour open house from 9 to 1 p.m. on Biodiversity Museum Day? The Bohart will be one of 13 museums or collections open to the public and the event if free and family friendly.

"They will see thousands of species of butterflies--and maybe moths if we open those aisles as well--that they have never seen before," Smith says. "They can learn about the defensive strategies these insects use for survival, such as camouflage, warning coloration, mimicry of other species. We love to teach about the importance of Lepidoptera in the environment, either to their habitat directly or possibly as an indicator of the health of their habitat. And, of course, they can be amazed at the beauty of these insects."

This is truly a global collection.

"We have specimens from all over the world, from every continent," Smith notes. "We are especially strong, of course, in North American material but also strong in Central and South America, and these areas represent much of our continuing growth. We have a great deal of material from Papua New Guinea, Australia, Indonesia, Malaysia, Taiwan, and other eastern Asian countries. We have a great amount of material from Africa, particularly Zambia and Democratic Republic of the Congo. We are especially strong with northern Mexico moths, much of which likely represents species still undescribed by taxonomists."

Are endangered or threatened butterflies in the collection? Yes.

"We do have examples of most of the threatened and endangered species of butterflies, and even examples of some of the butterfly species now extinct (due to destruction of habitat by urbanization). Due to wonderful donations over the decades we have examples of very rare species from Asia and Africa, as well as a growing collection of the extraordinary Birdwing Butterflies from the Indonesian-Australian region."

The Bohart's monarch butterfly specimens comprise five drawers and they include specimens from the Pacific Islands, Australia and Eastern Asia, as well as the United States.

"Without a doubt, the biggest 'Wow Factor' comes from the huge and brilliant metallic blue Morpho butterflies from tropical America," Smith points out. "We also have four drawers of the Atlas moths from Asia, the largest insects in the world. We have specimens of the White Witch moth, with the widest wingspan of any Lepidoptera. We have many drawers of Asian swallowtails that are brilliant metallic blue and green, as well as the striking Birdwing Butterflies that are green, blue, gold, and HUGE."

Smith himself has collected many of them. "I have not kept track, but I have been passionate about Lepidoptera since 1967, have made 12 research trips to Latin America, and probably have collected 50,000 to 60,000 specimens myself, all of which reside in the Bohart collection."

Does he have a favorite?

"Oddly, my favorite group of butterflies may be the Arctics (genus Oeneis), which occur throughout the western United States, Canada, and to Alaska. I like them due to their habitat, normally, of high mountain areas, and they remind me of the thrill I feel when hiking in these areas. My favorite moths could be the wasp-mimics in the Arctiid moths, the subfamily Ctenuchinae. Hundreds of different species are found in the Neo-Tropics and their amazing colors and often strong resemblance to wasps intrigues me."

Smith, a resident of Rocklin, received a 2015 “Friend of the College” award from the UC Davis College of Agricultural and Environmental Sciences for his volunteer work, including preparing specimens and organizing the  collection. At the time he had spread the wings of more than 200,000 butterflies and moths, amounting to 33,000 hours of volunteer service.

Today it's many more. Many, many more.

“Entomology is my passion," he says, "and the Bohart Museum is my cause.”

Lynn Kimsey, director of the Bohart Museum and UC Davis professor of entomology, who nominated Smith for the award, praised him for completely reorganizing the butterfly and moth collection. “It's no small feat to rearrange this many specimens, housed in roughly one thousand drawers,” she said. “Many thousands of the specimens needed to be identified, and the taxonomy required extensive updating and reorganization.”

In her nomination letter, she wrote that “You could not ask for a better friend than Jeff Smith. He has brought us international acclaim and saved us $160,000 through donations of specimens and materials, identification skills and his professional woodworking skills. This does not include the thousands of hours he has donated in outreach programs that draw attention to the museum, the college and the university.”

Kimsey, who has directed the museum since 1989, remembers when Smith joined the museum. “When Jeff was working for Univar Environmental Services, a 35-year career until his retirement in 2013, he would spend some of his vacation days at the museum. Over the years Jeff took over more and more of the curation of the butterfly and moth collection. He took home literally thousands of field pinned specimens and spread their wings at home, bringing them back to the museum perfectly mounted."

It was the day that cockroaches stole the show.

However, bed bugs, carpet beetles and pantry pests got into the act and competed mightily for the spotlight.

The occasion: The UC Davis Bohart Museum of Entomology open house, held Sunday afternoon, Nov. 18. The theme:  "Urban Entomology."

The three-hour event starred a cockroach--well, a human dressed as a cockroach.

Karey Windbiel-Rojas of the UC Statewide Integrated Pest Management Program (UC IPM)--she's the associate director for Urban and Community IPM who serves as the area urban IPM advisor for Yolo, Sacramento and Solano counties--donned her cockroach costume and joined Bohart scientists in fielding questions about urban pests. 

The pests the UC IPM scientist has been dealing with lately include carpet beetles, bed bugs and pantry pests. She handed out two newly published Quick Tips on carpet beetles and pantry pests, as well as information on other pests.  What are some of the other pests?  Check out UC IPM's Quick Tips library at http://ipm.ucanr.edu/QT/index.html.

UC IPM offers a wealth of information on its website, including

• home, garden, turf and landscape pests
• agricultural pests
• natural environment pests, and
• exotic and invasive pests

But when a cockroach is scurrying about (that was Karey's Halloween costume, by the way), the mind focuses on the "ins" and "outs" of cockroaches. Mostly the "outs."

As in: Stay. Out. Never. Ever. Come. Back. In.

"There are six species of cockroaches in California that can become pests: German cockroach, brownbanded cockroach, oriental cockroach, smokybrown cockroach, American cockroach, and Turkestan cockroach. A seventh species, the field cockroach, is not really a pest. It is usually found outdoors, but sometimes comes indoors when it is hot or dry and is often mistaken for the German cockroach. Of these seven species, the one that has the greatest potential for becoming persistent and troublesome is the German cockroach, which prefers indoor locations. Oriental and American cockroaches occasionally pose problems in moist, humid areas."--Excerpt from UC IPM Pest Note on Cockroaches.

As the UC IPM website indicates, cockroaches "may become pests in homes, schools, restaurants, hospitals, warehouses, offices, and virtually in any structure that has food preparation or storage areas. They contaminate food and eating utensils, destroy fabric and paper products, and impart stains and unpleasant odors to surfaces they contact."

Cockroaches can definitely give you a difficult time.

And speaking of giving, today (Tuesday) is Giving Tuesday, and UC IPM Director Jim Farrar has committed to eating a pest if at least 20 people make a donation of $10 or more to UC IPM. 

UC Agriculture and Natural Resources (UC ANR) spokesperson Pamela Kan-Rice, assistant director of News and Information Outreach, informed us: "With your donation and Jim's appetite, there will be one less pest to deal with! Spread the word to colleagues, family and friends to help UC IPM meet this goal. All UC IPM donors will be invited to the special pest eating event which will take place in the afternoon on Wednesday, Nov 28 in the UC ANR building." The dining experience is expected to begin at 4 p.m.

Here's where to donate before midnight tonight:  https://donate.ucanr.edu/pages/integrated-pest-management.

We asked Karey if the pest to be consumed could possibly be a cockroach. Or a garden-variety pest, such as a dandelion.

"To my knowledge he will not be eating a cockroach or a dandelion," she commented in an email. "I don't want to give away what he might be eating (so I don't actually know for sure)."

That would be a definite "no" on the roach!

(Update: Director Farrar ate corn smut, grasshoppers and live mealworms.)
