That sign greets visitors to the Bohart Museum of Entomology, University of California, Davis, and that's exactly what Noah Crockette, 18, an intern there since age 11 and the winner of an international beetle research award as a teenager, plans to do.
This week he's already gone far--a distance of more than 2700 miles--from Davis to Ithaca, N.Y., where he is majoring in entomology at Cornell University.
Fondly known as “The Beetle Boy,” Noah won the 2015 Coleopterists' Society Award (senior division) for his project, “Survey of the Dung Beetles of Stann Creek, Belize.”
He volunteers at the Bohart Museum, home of nearly eight million insect specimens, and a live petting zoo of Madagascar hissing cockroaches, walking sticks and tarantulas. He has helped out with open houses, outreach programs and collecting trips.
“Yes, Noah has been volunteering here for quite a few years,” said Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis. “We've seen him go from a middle school kid to a very mature 18-year-old. He's a great kid, always ready with a big smile, great attitude and really hard working. Smart, too. He should do very well at Cornell. We already miss him.”
Two Cornell University alumni--Tabatha Yang, the Bohart Museum's education and outreach coordinator, and UC Davis doctoral candidate student Emily Bick of the Christian Nansen lab, serenaded him with the Cornell fight song. Yang's degree is in general biology, and Bick's degree in entomology. After they sang the fight song, they told him how cold the winters are!
His major advisor is drosophila (fruit flies) expert Patrick O'Grady, who taught at UC Berkeley for 12 years before joining the Cornell faculty last year. His ecology professor is UC Davis alumnus Anurag Agrawal, an ecologist who received his doctorate in 1999, studying with Richard Karban.
His acceptance into Cornell, one of the top-ranked entomology programs in the country, came in 2017. Noah graduated in 2017 from The Met Sacramento High School, and Cornell offered him a one-year student transfer contract for the fall of 2018.
“I have always been interested in bugs but my interest in entomology started in sixth grade,” Noah said. “I mostly became interested in insects through my internship at the Bohart and participating in the undergraduate UC Davis Entomology Club (open to all interested persons). Before then I had only known that I was interested in zoology and started going to the Ent Club after learning about it from talking to (UC Davis forensic entomologist and club advisor) Robert “Bob” Kimsey at UC Davis Picnic Day. After attending the club for awhile, Danielle Wishon (club president and entomology major) and Bob got me connected with the Bohart to start the internship from which my interest grew.”
Career plans? Noah is keeping his options open as to specialty, but he wants to work in research. Beetles fascinate him, especially scarab beetles. “I have a tendency towards scarab beetles,” he said. “I particularly like the tribe Cyclocephalini, the masked chafer beetles. I really like that they are a Dynastines like the Hercules beetles but lack any sort of horns or other glitzy features. Even though they are small and brown, I love the subtle beauty of the markings which remind me of the Rorschach ink tests.
”I also really love venom so I have also thought about going into venom research but would like to grow more familiar with it before considering it more.”
As a Bohart Museum intern and associate, Noah collected insects twice in Belize on Bohart-affiliated collecting trips “where I was able to get field work experience in entomology as well as herpetology and ornithology.” Fran Keller, assistant professor, Folsom Lake College, and David Wyatt, an entomology professor at Sacramento City College, led the collecting trips. Keller, who served as his mentor, received her doctorate in entomology from UC Davis, studying with Lynn Kimsey.
“My last trip to Belize," Noah said, "was when I completed my Coleopterists' Society project in which I designed and constructed 12 baited pitfall traps which I used to survey the dung beetle species on the property as well as determine their preferred bait, between human feces, pig feces, chicken manure, rotten chicken, and rotten fruit."
In his freshman year, Noah taught an entomology class to elementary students, and as a senior project, organized a museum day at Shriners Hospital for Children.
Outside of entomological pursuits, he enjoys hiking, kayaking and birdwatching. “I really love the outdoors,” he said. “Last year after my trip to Belize I was also given the opportunity through my school to go on a month-long backpacking and kayaking trip through the National Outdoor Leadership School (NOLS) in Alaska. I also played rugby for C.K. McClatchy High School during my senior year which was a fun experience and I now plan on continuing with the sport. At home I like to keep reptiles and invertebrates--mostly tarantulas--as pets and enjoy collecting zoology related books and objects.”
During the going-away party, a photo of Noah Crockette flashed on the wall-mounted computer screen. It pictured him at about age 14, enthusiastically working with insects.
Doing what he loves.
Not overlooked was the quote from noted scientist E. O. Wilson “Go as far as you can [young scientists]. The world needs you badly."

There's a new bear in town.
Stuiffed toy animals resembling tardigrades, aka "water bears," are all the rage at the Bohart Museum of Entomology's year-around gift shop at the University of California, Davis.
The bright blue plush toys are just as cuddly, fluffy and pudgy--if not more so--than the traditional teddy bear.
Lynn Kimsey, director of the Bohart Museum and professor of entomology, UC Davis Department of Entomology and Nematology, wrote about the tardigrades in her newsletter several years ago.
The water bear "has to be one of the most peculiar and indestructible groups of animals known," she wrote. The microscopic and nearly indestructible tardigrade can survive being heated to 304 degrees Fahrenheit or being chilled for days at -328 F. And, even if it's frozen for 30 years, it can still reproduce. See video on EurekAlert.
They belong to their own phyllum, the Tardigrada (meaning "slow steppers"), and to date there are some 1,500 described species throughout the world. "Tardigrades can survive high pressures of more than 1,200 atmospheres found in the bottom of the abyss," Kimsey related. "They can tolerate 1,000 times more ionizing radiation than other animals."
"This collection is the result of years of collecting, mounting, imaging, and identifying by former collection manager Bob Schuster and emeritus professor Al Grigarick and their collaborators," she noted.
What's the water bear look like? It has a barrel-shaped body, eight pudgy legs, and the adults usually range from 0.3 to 0.5 mm in length.
German zoologist Johann August Ephraim Goeze (1731-1793) first described the critters in 1773, referring to them as "kleiner Wasserbär," or "little water bears."
They're easiest to find on lichens and mosses, Kimsey says, but they can also be found on beaches, in the subtidal zone, freshwater sediments, soil, hot springs and even on barnacles. They've been found "high in the Himalayas to down in the deep sea." They've even been found in the interior of Antarctica.
They mostly feed on plants or bacteria "but some are predators on smaller tardigrades," Kimsey says. They use the stylets in their tubular mouth (snout) to pierce "individual plant or bacterial ells or small invertebrates."
Why is the water bear so indestructible? In research published in 2016, geneticist Takekazu Kunieda and his colleagues from the University of Tokyo found that the water bear expresses a tardigrade-specific protein that binds itself to DNA. This acts like a "shield against x-ray radiation, preventing the DNA from snapping apart," according to an article published in Gizmodo.
Bottom line: the real "water bear" is definitely less destructible than its huggable, plush counterpart in the Bohart gift shop.

Have you ever seen an ambrosia beetle, a red turpentine beetle, an ice cricket, a brine fly or a sand wasp?
You will if you attend the UC Davis Bohart Museum of Entomology open house on “Extreme Insects: Fire and Ice,” on Sunday afternoon, Aug. 19.
The public event, to take place from 1 to 4 p.m. in Room 1124 of the Academic Surge Building, Crocker Lane, is free and family friendly. It will emphasize "fire and insects."
“There are a number of species that are specifically attracted by smoke to damaged trees,” said Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis. “Wildland fire fighters hate them because some of the beetles fly at them, crawling into their turnouts and biting them. Fire insects include jewel beetles, some horntail wasps and a few others."
In addition to fire insects, Kimsey said that the Bohart open house will cover other insects adapted to extremes:
- Ice: ice crickets and ice flies, both native to California
- Extreme acid: midges that live only in highly acidic mine run-off
- Hot water: midges found in hot springs just below the boiling point
- Salt: the brine flies of Mono Lake.
- Desert: sand wasps
Regarding the beetles that attack the firefighters, these are “The flatheaded borers (Buprestidae) and they will actually nip the firefighters as they land,” said chemical ecologist Steve Seybold with the USDA Forest Service, Pacific Southwest Research Station, Davis, and a lecturer/researcher with the UC Davis Department of Entomology and Nematology.
Insects that like ethanol/burned phloem include the red turpentine beetle, the ambrosia beetles, the "sour cambium" beetles, and some of the larger woodborers, Seybold said. “These are the 'undertakers' of the trees, if you will. Certain bark and ambrosia beetles specialize in colonizing burned tissue that gives off ethanol as a sign of fermentation. These insects wait until things have cooled off a bit before they bore into the trees."
"Often when you visit a burned area," Seybold said, "you'll see piles of white dust coming out of the trees that have blackened bark. This dust is made by ambrosia beetles--and other larger woodborers--that can make use of the carbon that is still present in these moribund trees. Ambrosia beetles 'consume' this carbon indirectly by farming fungi in their galleries. The fungus serves as a conduit for the nutrients in the wood. Some of the larger woodboring insects have other adaptations like specialized enzymes that degrade cellulose or hemicellulose."
Seybold called attention to an article titled “Attraction of Melanophila Beetles by Fire and Smoke,” authored by noted beetle expert E. Gorton Linsley (1910-2000) and published in April of 1943 in Scientific Notes, the Journal of Economic Entomology. Linsley, who received his doctorate from UC Berkeley in 1938, wrote that thousands of cigarette smokers at the UC Berkeley football games were complaining of beetles swarming into the stadium and biting their hands and necks.
The smoke on "still days sometimes hangs like a haze over the stadium during a big game," wrote Linsley, identifying the beetles as Melanophilaconsputa Lec. and M. acuminata (family Buprestidae). M. consputa is commonly called “the charcoal beetle.”
Linsley also reported receiving "complaints from sawmill operators, fire fighters and smelter plant workers regarding annoyance by buprestid beetles of the genus Melanophila. These beetles appear to be greatly stimulated by heat and attracted by smoke. They normally breed in fire-scarred pines and under ordinary conditions, they are rarely encountered in nature. However, on hot days during the dry season, especially in late summer and fall, they sometimes fly in unbelievable numbers to forest fires, burning refuse dumps, refineries, smelter plants, etc.”
Wildfires continue to rage in California. As of Aug. 13, the 5,255 California wildfires this year have burned 958,812 acres, according to the California Department of Forestry and Fire Protection and the National Interagency Fire Center. To date, the still-active Mendocine Complex fire, the largest wildfire in California history, has charred more than 344,000 acres.
The Bohart Museum open house also will include a family craft activity involving extreme insects. The museum houses a global collection of nearly eight million specimens and is the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. It also houses a live "petting zoo" of Madagasar hissing cockroaches, walking sticks, tarantulas and praying mantids, and a year-around gift shop, stocked with 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. It is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free. More information on the Bohart Museum is available on the website or by contacting (530) 752-0493 or emailing bmuseum@ucdavis.edu.

They brought home five gold or first-place awards: three silver or second-place awards; and two bronze or third-place awards. “That was quite a haul!” commented an ACE member on Facebook.
The recipients:
- Diane Nelson, College of Agricultural and Environmental Sciences, two golds
- Kathy Keatley Garvey, Department of Entomology and Nematology, one gold and one silver
- Jim Downing, California Agriculture journal, gold
- David Slipher, College of Biological Sciences, gold
- Steve Elliott, Western IPM Center, two silvers and a bronze
- Gregory Watry, College of Biological Sciences, bronze
Nelson wrote about pig personalities and polar bears. Slipher's topic was pigeons. (See other topics in the awards news story)
And me--bugs. The news story that won the gold (by yours truly) involved a visit to the Bohart Museum of Entomology by children of California migratory workers.
The piece, “Why These Youngsters Want to Become Entomologists” (https://bit.ly/2sYwhye) covered the children's tour of the insect museum, which houses some eight million insect specimens, a live "petting zoo" (Madagascar hissing cockroaches, walking sticks, tarantulas and praying mantids), and a year around-gift shop. The students engaged the director, Lynn Kimsey, professor of entomology at UC Davis, in a press conference. They asked the "who, what, when, where and how come" questions like pros. It was delightful to see them so well prepared and perceptive.
The Bug Squad blog that won silver (https://bit.ly/2BrePU5) involved a late-season monarch caterpillar that we found Oct. 27, 2017 on one of our milkweeds in our pollinator garden in Vacaville. It formed a chrysalis on Nov. 4.
On Day 19, Nov. 22 (the day before Thanksgiving), it happened. The monarch eclosed. A big, strong and healthy girl.
What to do...no way could she fly three hours in the rain and cold from Vacaville to an overwintering site in Santa Cruz. And with predators abounding, survival looked bleak.
From the Bug Squad blog:
"It just so happened that a friend and pollinator advocate, Rita LeRoy, the self-described 'farm keeper' at the Vallejo City Unified School District's Loma Vista Farm, was heading to Santa Cruz on Friday, the day after Thanksgiving, to show her out-of-town relatives the overwintering migratory butterfly sanctuary at the Natural Bridges State Beach Park. That's about a 100-mile trip from Vallejo.
"Could Ms. Monarch hitch a ride?
"She could. And she did."
Rita is a Monarch Mom (she rears and releases monarchs) and is active in the Bay Area-Based Pollinator Posse. She teaches Vallejo City Unified School District youngsters about farming, cooking and gardening. And that includes gardening for butterflies.
So Ms. Vacaville Monarch hitched a ride with Rita and her family.
"She flew so fast that we didn't get a picture of her flying away," Rita related. "She was anxious to join her new friends."
A happy ending.
And hopefully, Ms. Vacaville Monarch provided the butterfly world with another generation.

Just call it "my old flame."
Well, it's not mine, but it is a flame of sorts, a flame skimmer dragonfly (Libellula saturata) and it's firecracker red.
We see this species frequenting our pollinator garden in Vacaville, which includes a fish pond, flower beds, and bamboo stakes for their perches.
If you like dragonflies, you may want to purchase a dragonfly poster at the gift shop in the Bohart Museum of Entomology, located in Room 1124 of the Academic Surge building on Crocker Lane, UC Davis. It features 18 species of dragonflies, ranging from the common whitetail and green darner to the Western river cruiser and the bison snaketail. And, of course the flame skimmer.
The poster? It's the work of former UC Davis entomology doctoral candidate Fran Keller, now an assistant professor at Folsom Lake College, and naturalist/photographer Greg Kareofelas of Davis. Keller received her doctorate in entomology, studying with Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis.
