Congrats to the University of California recipients of awards from the Association for Communication Excellence (ACE), an international association of communicators, educators and information technologists who focus on communicating research-based information.
ACE officials recently handed out gold, silver and bronze awards at their 107th annual conference, held in Asheville, N.C. ACE's first conference occurred July 10, 1913, when land-grant college agricultural editors gathered at the University of Illinois.
And now, the California winners:
The University of California Statewide Integrated Pest Management Program (UC IPM) won the gold award in the Information Technology category, Instructional Design for a Non-Academic Public Online Course, for its “Self-Paced Online Course: Urban Pyrethroid and Fipronil Use-Runoff and Surface Water Protection.”
The team: Petr Kosina, Cheryl Reynolds, Robert Budd, Aniela Burant, Carlos Gutierrez, Karey Windbiel-Rojas and Loren Oki.
The course, for pest management professionals who work primarily in structural pest control or landscape maintenance, “presents information on the Surface Water Protection Regulations that were put into place to reduce the amount of pyrethroids in surface water runoff. It discusses the types of applications allowed under the regulations as well as those that are prohibited and those that are exempt." The course, available for free, must be completed by Dec. 30 of the current year.
Kathy Keatley Garvey (yours truly), communication specialist for the UC Davis Department of Entomology and Nematology, won a bronze award (third place) in the pictorial series category. Her submission included a series of monarch images published July 27, 2022 on her Bug Squad blog, UC Agriculture and Natural Resources website.
Headlined “Monarch Butterflies: Closer to Extinction,” the blog included photos of a monarch egg, caterpillar, chrysalis and male and female butterflies, all images she captured in her family's pollinator garden in Vacaville.
The blog dealt with International Union for Conservation of Nature (IUCN) announcement on July 21, 2022 that the migratory monarch butterfly (Danaus plexippus) is now on its "Red List of Threatened Species as Endangered--threatened by habitat destruction and climate change."
Wrote Garvey:
“The good news? That the iconic monarch landed on the Red List, which means opening safeguards to protect it."
“The bad news? Being on the list means that it's closer to extinction. The other bad news? The U.S. Fish and Wildlife Service, has not yet listed it as endangered or threatened, only that it's a candidate for its list of endangered and threatened wildlife."
“The sad news? The IUCN Red List now includes 147,517 species, of which 41,459 are threatened with extinction."
Garvey launched the Bug Squad on Aug. 6, 2008 and writes it every night, Monday through Friday. The insect blog draws worldwide rankings and accolades.
The ACE winners represent universities or higher institutions of learning in 18 states: Alabama, Arkansas, California, Connecticut, Florida, Georgia, Iowa, Kansas, Kentucky, Louisiana, Mississippi, New Mexico, North Carolina, Oklahoma, Oregon, Tennessee, Virginia and Wyoming. (See list)

Lady beetles, green fruit beetle larvae, and stick-on bug tattoos drew inquisitive and appreciative crowds when the UC Statewide Integrated Pest Management Program (UC IPM) staffed an informational booth at Briggs Hall during the 109th annual UC Davis Picnic Day.
Forensic entomologist Robert Kimsey and doctoral student Grace Horne of the Emily Meineke lab, UC Davis Department of Entomology and Nematology, chaired the department's Picnic Day Committee. (See 'What's a Picnic Without Bugs?)
Lady beetles?
Karey Windbiel-Rojas, associate director for Urban and Community IPM/Area IPM Advisor, said attendees asked scores of questions. "Questions were quite varied but those that stood out were how to control: termites, aphids, caterpillars, ants, carpet beetles, and rats," she said.
Green fruit beetles?
Another popular draw: Green fruit beetle larvae. "They were fun for people to get hands-on with and gave us the chance to talk to people about the difference between look alike scarab beetle larvae," Windbiel-Rojas wrote in an email. "Japanese beetles (which are not established in California), masked chafer beetles (their grubs ARE pests in raised garden beds and lawns) and green fruit beetles (which are not really pests but people sometimes see them in compost)."
"The green fruit beetle (scarab, family Scarabaeidae), is also called a fig eater beetle, green fig beetle, or western green June beetle," according to the UC IPM website. "The adults are an occasional pest of ripe fruits. Adults can fly a relatively long distance and are highly attracted to ripe fruit and the odors of manure and fermenting fruit."
Tattoos?
UC IPM gave away 500 stick-on (temporary) tattoos, including images of the Chinese red-headed centipede (Scolopendra subspinipes mutilans), tarantula hawk (Pepsis heros) and the hickory horned devil caterpillar of a regal moth (Citheronia regalis). They were all gone within a few hours. "Next year we plan to order 1000," Windbiel-Rojas said. Staffing the educational table that included the tattoos were her two sons, Diego, a freshman at McClatchy High School in Sacramento, and Spencer, a seventh grader at Sutter Middle School in Sacramento. As attendees examined and applied the tattoos, the youths talked about invasive pests and the importance of not moving firewood to spread pests.
Meanwhile, at the entrance to Briggs Hall, it was "beetle mania" as members of the UC Davis Entomology Graduate Student Association kept busy selling their beetle t-shirts, the most popular of their insect-themed t-shirts.

It wouldn't make the news, even if it were a "Slow News Day."
"Lady in Red Climbs Neon-Pink Petals in Search of Aphids."
Lady beetles, aka ladybugs, are coming out of their winter hibernation now and they're hungry. Aphid-hungry.
We spotted this lady beetle Feb. 7 in a flower pot containing an iceplant, Carpobrotus edulis, native to South Africa. Iceplant is an invasive plant.
"Iceplant was introduced to California in the early 1900s as an erosion stabilization tool used on railroad tracks, and later used by Caltrans on roadsides," according to an article, "Invasive to Avoid--Iceplant," posted by the California Fish and Wildlife. "It has been used as an ornamental for many years, and is still sold in nurseries. Unfortunately, iceplant spreads easily, and has become invasive in coastal California from north of Humboldt County to as far south as Baja California. When it establishes in a location, it forms a large, thick mat that chokes out all other native plants and alters the soil composition of the environment. Because it is a coastal invader, it competes with many endangered, threatened, and rare plants." (See what Calflora.org says about it.)
California has about 200 species of lady beetles. Check out the lady beetles on the University of California Statewide Integrated Pest Management Program (UC IPM) to see many of the species. They are voracious consumers of aphids and other soft-bodied insects.
Meanwhile, a news flash: "Lady in Red Climbs Neon-Pink Petals..."

So begins author Chris Alice Kratzer in the preface of her new book, The Social Wasps of North America, published by the company she founded in 2020, Owlfly LLC.
But what she writes is neither true nor what she believes.
Kratzer quickly points out that wasps are "essential, complicated and beautiful."
Indeed, they play important roles in our ecosystems. For one, they provide a beneficial service: natural pest control. Look, ma, no pesticides! Two, they're pollinators.
This book is more than a labor of love. it's a passionate, dedicated look at wasps, written in a conversational tone by a long admirer and supporter of the insects.
Kratzer, who grew up in New Jersey where she continues to live, remembers interacting with insects in her environment, and yes, getting stung multiple times by assorted insects, including wasps. That comes with the territory. Did she become an entomologist? No, she opted to become an engineer. Kratzer received a bachelor of science degree (2019) in mechanical engineering, energy and the environment, from Rochester Institute of Technology. She worked full time as a engineer in New York until May 2020. Today she's the executive director of Owlfly, managing its two divisions, Owlfly Engineering and Owlfly Publishing.
As Kratzer writes on LinkedIn: "I founded Owlfly LLC in 2020 as an opportunity to develop, produce, and market sustainable technologies and publications that demonstrate high potential for climate change mitigation."
Wasps continue to fascinate her and fold her into the Hymenoptera world.
You may want to know why wasps sting, how to avoid the stings, and what to do if you're stung. She tells you.
She explains the meaning of inquilines. "An inquiline (also called a cuckoo or social parasite) is an animal that exploits the next of another animal in order to lay its eggs or raise its young."
She writes about prey and food sources. She calls attention to the fact that social wasps "catch and dismember prey with their strong mandibles." And did you know that "their tiny waists prevent them from eating any sold fluids?"
Caterpillars, she says, are "the primary food source for most social wasps." Wasps also "hunt grasshoppers, crickets, katydids, moths, butterflies, beetles, flies, earthworms, lanternflies, cockroaches, smaller wasps, small spiders and cicadas."
There aren't many engineering-trained professionals who write so well and knowledgeably about insects as Kratzer. She began writing her book in 2018, and by January 2020, at age 25, published it. Her path to writing the book included: holing up in the Cornell University Insect Collection; networking with experts; learning how to read taxonomic papers; and teaching herself to write software "to align and compare genetic barcodes.
"I spent close to a thousand hours poring over observations on the community science platform iNaturalist by identifying wasps, mapping ranges and studying color variations," she writes.
The result is this incredible 400-page book, billed as field guide "to all known species of social wasps from the high arctic of Greenland and Alaska to the tropical forests of Panama and Grenada." It covers 208 species in 22 genera, and features some 900 color illustrations. Many of the images are from macro photographers posting to iNaturalist.
Her book brings back memories of Iowa State University Professor Amy Toth's May 2015 seminar on wasps at the UC Davis Department of Entomology and Nematology. Toth told the crowd that wasps are pollinators, they attack pests of agricultural crops, they are extremely intelligent, they are artists, and they are "beautiful, complex and fascinating creatures." She coined the hashtag, #wasplove.
Who knew there are so many species of 'jackets? The one familiar in California is the Western yellowjacket, Vespula pensylvanica.
Kratzer also elaborates on paper wasps. We in California know well the European paper wasp, Polistes dominulo. But did you know its scientific name, dominulo, means "little mistress?" And, as its name implies, it's native to Europe. Introduced in the United States (Massachusetts) in the 1970s, "it has since become a major pest species and one of the most abundant wasps on the continent," she writes.
We remember "Wasp Woman" Lynn Kimsey, director of the Bohart Museum of Entomology and a UC Davis distinguished professor of entomology, telling us about the differences between European paper wasps and Western yellowjackets. (See Bug Squad blog,) "European paper wasps (Polistes dominula) are not scavengers. They only take live insects, particularly caterpillars. Western yellowjackets, Vespula pensylvanica, are serious scavengers..." (Not to mention the fact that the yellowjackets have dark antennae and the paper wasps, orange.)
Note that the UC Statewide Integrated Pest Management Program (UC IPM) provides a wealth of information on Western yellowjackets and paper wasps in its PestNote: "In Western states there are two distinct types of social wasps—yellowjackets and paper wasps. Yellowjackets are by far the most troublesome group, especially ground- and cavity-nesting ones such as the western yellowjacket, which tend to defend their nests vigorously when disturbed. Defensive behavior increases as the season progresses and colony populations become larger while food becomes scarcer. In fall, foraging yellowjackets are primarily scavengers, and they start to show up at picnics and barbecues, around garbage cans, at dishes of dog or cat food placed outside, and where ripe or overripe fruit are accessible. At certain times and places, the number of scavenger wasps can be quite large."
The colorful little tidbits that Kratzer sprinkles throughout her book are intriguing. For instance, the Western yellowjacket is NOT found in Pennsylvania despite its species name, pensylvanica. Someone mislabeled the original specimens. And by the way, its sting is rated 2/5 (painful) on the Schmidt Sting Pain Index.
Bottom line: The Social Wasps of North America is an eye-opener, a page-turner and a mind-boggler that offers a field-guide approach to social wasps. This book belongs in your library whether you're a scientist, a citizen scientist or a curious person who just wants to know about the incredibly diverse social wasps that live in our amazing world.
And, at your next gathering of social (and anti-social) folks, ask if anyone knows the origin of the species name, dominula....
Little mistress!

If you like your insects long, slender and delicate, and resembling a flying neon needle, the damselfly is for you.
Who can resist watching them and photographing them?
The common blue damselfly or Northern Bluet (Enallagma cyathigerum) is as thin as a needle, a jeweled blue needle.
We've seen them hover in our yard, like mini-helicopters--oops, make that "skinny mini" helicopters--and then touch down on a leaf to feast on small insects.
Damselflies share the same order, Odonata, as their larger cousins, the dragonflies. As any entomologist will tell you, damselflies belong to the suborder Zygoptera, and dragonflies, Anisoptera. They are an ancient group, with fossil records showing they existed at least 250 million years ago.
Odonata means "toothed" and Zygoptera means "paired wings."
Damselflies are no "damsels in distress." They're daytime hunters that "consume large quantities of other insects such as flies, mosquitoes and moths and some eat beetles and caterpillars," according to a Texas A&M University (TAMU) website.
Some other facts on the TAMU site:
- In prehistoric times, dragonflies and damselflies were as huge as hawks and were "the largest insects to ever live."
- Worldwide, there are more than 4700 species of Odonata, with Zygoptera accounting for a third fo them
- Males of most damselfly species are brighter-colored than females
- Damselflies neither bite nor sting.
The UC Statewide Integrated Pest Management (UC IPM) describes damselflies this way: "The head is narrow with bulging eyes, long antennae, and tubular-sucking mouthparts. The legs are long and the front pair are slightly swollen with inconspicuous spines. Adults and nymphs can move rapidly when disturbed or stalking prey."
A photography tip: if you spot a damselfly, approach it with your camera already raised. A sudden movement may spook them.
