"Kleptopharmacophagy, a newly described behavior recently observed in milkweed butterflies, is characterized by adult butterflies feeding on milkweed caterpillars. What type of alkaloids do the adult butterflies presumably gain as a result?"
That was one of the questions posed during the Entomology Games at the 2021 Entomological Society of America (ESA) meeting.
What's the answer? Pyrrolizidine alkaloids.
What, you ask, are the Entomology Games? A lively question-and-answer, college bowl-style competition on entomological facts played between university-sponsored student teams, as ESA says.
If you've ever been to the Entomology Games (formerly the Linnaean Games), you know how wonderfully educational and purely entertaining they are. Check out the list of YouTube videos in the championship matches. The 2018, 2016 and 2015 videos are there. The UC Entomology Games Team (UC Davis and UC Berkeley) won the nationals in 2018, and UC Davis in both 2016 and 2015.
Next month is the Pacific Branch, Entomological Society of America (PBESA) competition, with the championship team and runner-up team eligible to complete in the nationals.
The PBESA meeting takes place April 10-13 in the Hyatt Regency Sonoma Wine Country. Santa Rosa. The preliminary round is from 5 to 6 p.m., April 10. Plans are to hold three rounds with questions from each of the 10 categories: Biological Control, Behavior and Ecology, Economic and Applied Entomology, Medical-Urban-Veterinary Entomology, Morphology and Physiology, Biochemistry and Toxicology, Systematics and Evolution, Integrated Pest Management and Plant-Insect Interactions, History of Entomology, and Entomology in Popular Culture. (See 2021 sample questions.)
The final round is from 8 to 10 p.m., April 11. Then the top two PBESA teams will head to the nationals. The Nov. 13-16 ESA meeting n Vancouver, British Columbia is a joint meeting with the Entomological Society of Canada (ESC), and the Entomological Society of British Columbia (ESBC). The theme: "Entomology as Inspiration: Insects through Art, Science, and Culture."
Some of the questions asked at previous matches have involved the work entomologists affiliated with the UC Davis Department of Entomology and Nematology:
- Emerita Mary Lou Flint, a longtime leader of the UC Statewide Integrated Pest Management (UC IPM) Program and an Extension entomologist based in the department;
- Rebecca Godwin, who received her doctorate from UC Davis and is now an assistant professor of biology at Piedmont University, Demorest, Ga.; and Jason Bond, the Evert and Marion Schlinger Endowed Chair and associate dean, UC Davis College of Agricultural and Environmental Sciences.
- Robbin Thorp (1933-2019), distinguished emeritus professor known for his expertise on bumble bees, including Franklin's bumble bees, now feared extinct
Q. Mary Lou Flint's textbook, IPM in Practice; Principles and Methods of Integrated Pest Management, cites the management of what invasive plant, first introduced to North America from Europe, as an "excellent example of classical biological control in the Western US?" This plant was controlled by importing the European chrysomelid beetle Chrysolina quadrigemina.
A. Klamath weed / St. John's Wort / Hypericum perforatum
Q: In early 2021, (Rebecca) Godwin and (Jason) Bond described 33 new species of the trapdoor spider genus Ummidia, including a species named in honor of what alt-country singer-songwriter, who was the most-nominated woman at the 2019 Grammy Awards? She has had success both as a solo artist and as a member of the all-female supergroup The Highwomen, and her annual music festival "Girls Just Wanna Weekend" is held in Mexico near the type locality of her namesake trapdoor spider. Name this singer.
A: Brandi Carlile
Q: What bee species, only known from California and Oregon, was added to the Endangered Species List in September 2021?
A: Franklin's bumble bee (Bombus franklini)
How about some more questions?
Q. Earwigs are known for their maternal care, but the species Anechura harmandi goes above and beyond in its support. What describes the extreme contribution of A. harmandi mothers to the success of their offspring?
A: Matriphagy; the survival rate of the offspring is increased when they consume their mother after parental care is complete
Q: Halictid bees parasitized by the strepsipteran species Halictoxenos borealis were recently shown to exhibit unusual behavior when visiting flowers. The parasitized bees did NOT collect or eat pollen; they instead bent their abdomens downward and pressed them against the flower. According to the authors of this study, how did this behavior directly benefit the first-instar strepsipterans living in the bees?
A: Pressing the abdomen against the flower makes it easier for the mobile first-instar strepsipteran larvae to move onto the flower and wait for a new host bee to arrive
Q: Developed during World War II by USDA employee Samuel Gertler, what widely used chemical compound can be synthesized using the reagents diethylamine and meta-toluic acid?
A: DEET / diethyltoluamide / n,n-diethyl-meta-toluamide / n,n-diethyl-3-methylbenzamide
Q: Most contact insecticides are able to penetrate the insect exoskeleton because they contain a fat-soluble compound. What is the term for this type of chemical compound?
A: Lipophilic compound
Q: The solitary bee Eucera pruinosa (formerly in the genus Peponapis) is an efficient pollinator of what crop? There are multiple correct answers, but one of them is particularly appropriate, considering what day it is.
A: Pumpkins, cucumbers, squash, and other cucurbits
Q: Animals in the livestock, poultry and aquaculture industries often consume feed that has been supplemented by insect protein. This protein frequently comes from Hermetia illucens, a dipteran known by what common name?
A: Black soldier fly
Q: The leafcutter ant, Atta cephalotes, has hardened, distinctly sharpened mandibles that allow it to efficiently cut leaves. What mineral found in the mandibles provides this distinct sharpness? This mineral is also a metallic element with atomic number 30 on the periodic table.
A: Zinc
Q: What entomological acronym was used to refer to a group of American women who worked as auxiliary service pilots for the US during World War II?
A: WASP (Women Auxiliary Service Pilots)
Q: In 2018, Rachel Brosnahan won an Emmy for Outstanding Lead Actress in a Comedy Series, for playing a character with what dipteran nickname?
A: Midge (Miriam ‘Midge' Maisel from The Marvelous Mrs. Maisel)
Q: What British guitarist, who died in 2001, was memorialized by a pine tree planted in Los Angeles' Griffith Park? In an unfortunate, and somewhat ironic, development, the pine tree was later killed by an infestation of beetles.
A: George Harrison of The Beatles
Q: Keteoko is a traditional "honey feast" celebrated by the Enawene-Nawe people indigenous to the Brazilian Amazon. In order to collect large amounts of wild honey for the feast, the Enawene-Nawe have developed their own classification system, based on morphology, behavior, nest structure, and honey flavor, for identifying native species of what type of bee? Please answer with the common or scientific name of a tribe of Apidae.
A: Meliponini, stingless bees
Q: What insect family is essential for the production of iron gall ink? The ink is made using tannins extracted from oak galls, which are induced by larvae of this family.
A: Cynipidae
Did you get them all correct?

The popular cockroach races, hosted by the UC Davis Entomology Graduate Student Association (EGSA), will take place during the 107th annual UC Davis Picnic Day on Saturday, April 17, but you'll see them only on your computer screen--not in person.
That's because the 2021 Picnic Day is going virtual due to the COVID-19 pandemic precautions.
EGSA Picnic Day coordinator Erin "Taylor" Kelly, a graduate student in the laboratory of medical entomologist-geneticist Geoffrey Attardo lab, UC Davis Department of Entomology and Nematology, says the American cockroaches are housed in the basement of Briggs Hall and ready to go.
No personal trainers for them. "They will be pushed down the track by small pumps of air," she says.
Enthusiasts can cheer for their favorite racers and order stickers and roach race t-shirts from the EGSA website, which helps fund EGSA activities.
Where can you access the EGSA events on Saturday? On the UC Davis Picnic Day website at https://picnicday.ucdavis.edu
Here are the EGSA's 14 stations on tap. The links will all appear on the UC Davis Picnic Day website on or before April 17.
This is a live Zoom session from 12 noon to 3 p.m., with questions and answers. Folks can ask questions about insects and spiders.

A downloadable PDF from the lab of Professor Neal Williams, pollination ecologist, UC Davis Department of Entomology and Nematology. This involves whether bumble bees can take the heat: "Will the increase in extreme heat in California affect these cool-weather loving pollinators and their ability to persist?" This UC Davis research group is trying to figure this out. Folks can help them conduct this work by submitting observations of bumble bee nests in the Davis/Sacramento area so that monitoring efforts can begin gathering critical data.
A pre-recorded video. Learn about the Davis Fly Fishers Club.
A downloadable worksheet will be offered.
This will be pre-recorded/reposted video from the Sacramento-Yolo Mosquito Control District. Folks can learn about local vector control.
"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," Smith said.
The Bohart Museum, temporarily closed, is directed by Lynn Kimsey, professor of entomology.
