In the blink of an eye...
There it was, nestled inside a baby blue eyes blossom, Nemophila menziesii, which is a spring-blooming plant native to California, Oregon and Baja California.
"It?" A katydid nymph, a wingless critter with long black-and-white banded antennae.
The UC Statewide Integrated Pest Management Program (UC IPM) tells us that "nymphs appear in April and May and take 2 to 3 months to mature through 6 to 8 instars."
"At least 74 species of katydids (family Tettigoniidae) are present in California," according to UC IPM. "Most are not pests because they chew only a small amount of foliage before moving to another plant. Forktailed bush katydid (Scudderia furcata) can be a pest because it chews young fruit in addition to leaves. Angularwinged katydid (Microcentrum retinerve) and broadwinged katydid (Microcentrum rhombifolium) are other common species.--UC IPM post on katydids.
This nymph crawled around the blossom, stretched to reach the next one, and then, up and over it went.
Just a day in the life of katydid nymph on baby blue eyes.

Back in April of 2021, we wrote: "They're out there, and you don't have to crane your neck to see them."
The topic: crane flies. They're often mistakenly called "mosquito eaters" or "mosquito hawks." They're neither. They're members of the family Tipulidae of the order Diptera (flies).
Lynn Kimsey, director of the Bohart Museum of Entomology and UC Davis distinguished professor of entomology, emphasizes that crane flies don't eat mosquitoes. "In fact, adult crane flies generally don't eat at all," she points out. "Their entire brief adult lives are spent searching for mates and laying eggs." Crane flies are attracted to lights at night and you may find them around your porch light.
"Adult crane flies emerge from the soil beneath turfgrass, pastures and other grassy areas in late summer and fall," according to the UC Statewide Integrated Pest Management Program, part of the UC Agriculture and Natural Resources.. "The adults have very long legs and resemble large mosquitoes. Females mate and lay eggs in grass within 24 hours of emerging. Eggs hatch into small, brown, wormlike larvae that have very tough skin and are commonly referred to as leatherjackets.The leatherjackets feed on the roots and crowns of clover and grass plants during the fall. They spend the winter as larvae in the soil; when the weather warms in spring, they resume feeding. During the day larvae mostly stay underground, but on damp, warm nights they come to the surface to feed on the aboveground parts of many plants. When mature, the larvae are about about 1 to 1½ inch long. Around mid-May they enter a nonfeeding pupal stage and remain just below the soil surface. In late summer, pupae wriggle to the surface and the adults emerge. There is one generation a year."
It's not easy to photograph these slender, gangly, goofy-looking insects that resemble cartoon characters. If you spot them, they take flight. If you shadow them, they vanish. If you creep up upon them, they creep faster. If you say "Oh, well, Mr. Crane Fly, I didn't want to take your picture today anyway!"--that's when they pose.
I captured this image of a crane fly taking a break in a Spanish lavender bed on May 23, 2023. The morning light was just right.

It was a little late.
The first flameskimmer of the year usually arrives in our yard in early April.
Not this year. The species, Libellula saturata, was late.
The easily recognized red dragonfly, also known as "the firecracker skimmer," touched down in our yard today, May 24.
She perched on a bamboo stick in our pollinator garden, close to a fish pond, and eyed her surroundings.
It's amazing to watch them grab a flying insect and return to the perch to devour it.
Dragonflies belong to the order Odonata, which means "toothed one" in Greek.
Danish zoologist Johan Christian Fabricius, a student of Carl Linnaeus, coined the term Odonata in 1793. He is considered one of the greatest entomologists of the 18th century, according to Wikipedia. He named nearly 10,000 species of animals.

That's true for assistant professor Katie Thompson-Peer of the Department of Developmental and Cell Biology, UC Irvine, who will speak on "Cellular Mechanisms of Dendrite Regeneration after Neuron Injury” at the UC Davis Department of Entomology and Nematology seminar on Wednesday, May 24.
She uses the larvae and adult fruit fly, Drosophila melanogaster, as a model to study dendrite regeneration.
Thompson-Peer will present her seminar at 4:10 p.m. in Room 122, Briggs Hall. Her seminar also will be virtual. The Zoom link: https://ucdavis.zoom.us/j/95882849672
Her abstract: “Neurons have two types of cellular projections, that are essential for how they function in circuits: they have a single axon and a highly branched network of dendrites. These dendrites are the cellular structures that allow neurons to receive input from the environment or from other neurons. While much is known about how axons respond to injury, almost nothing is known about how neurons respond to dendrite injury. We have found that after dendrite injury, peripheral nervous system neurons are able to mount a reliable, reproducible process of dendrite regeneration. In this talk, I present our recent work to determine how neurons detect injury to their dendrites, using the larvae and adult fruit fly Drosophila melanogaster as a model to study dendrite regeneration.”
Thompson-Peer, who joined UC Irvine in April 2019, received her bachelor's degree in biology from the University of Pennsylvania, and then followed with a two-year stint at the Johns Hopkins University with Alex Kolodkin. She earned her doctorate from Harvard University, working with Josh Kaplan, and was a postdoctoral fellow with Yuh-Nung and Lily Jan at UC San Francisco and the Howard Hughes Medical Institute. Her postdoctoral work drew financial support from the National Institute of Neurological Disorders and Stroke F32 and K99/R00 fellowships, as well as a UC Office of the President's Postdoctoral Fellowship.
The Thompson-Peer lab explores how neurons recover from injury in vivo, and how this process is similar to and different from normal development. (See her work showcased on YouTube)
"At the most fundamental level, a neuron receives information along dendrites, and sends information down an axon to synaptic contacts," she writes on her website. "Dendrites can be injured by traumatic brain injury, stroke, and many forms of neurodegeneration, yet while the factors that control axon regeneration after injury have been extensively studied, we know almost nothing about dendrite regeneration. Our long-term research goal is to understand the cellular mechanisms of dendrite regeneration after injury."
"Our previous work found that the sensory neurons in the fruit fly Drosophila peripheral nervous system exhibit robust regeneration of dendrites after injury and used this system to explore central features of dendrite regeneration in developing animals, young adults, and aging adults. We have observed that after injury, neurons regrow dendrites that recreate some features of uninjured dendrites, but are unable to reconstruct an entire arbor that perfectly mimics an uninjured neuron. Moreover, there are mechanistic differences between the outgrowth of uninjured neurons versus the regeneration of dendrites after injury: dendrite regeneration is uniquely dependent on neuronal activity, ignores cues that constrain and pattern normal dendrite outgrowth, and confronts a mature tissue environment that is different from what a developing neuron would encounter. These challenges are significantly exacerbated when neurons in aging animals attempt to recover from injury."

The educational and entertaining activities drew them in.
The UC Davis-based California Master Beekeeper Program (CAMBP) was a huge part of it. CAMBP staffed an information booth, fielding questions about honey bees, bee health, and its organization; presented speeches on the UC Davis Speakers' Stage; and staffed an arts and crafts table where youngsters could get creative--and they did!--with bee-utiful decorations.
CAMBP, founded in 2016 by Cooperative Extension associate professor and apiculturist Elina Niño of the UC Davis Department of Entomology and Nematology, offers comprehensive, science-based information about honey bees and honey bee health. A continuous train-the-trainer program, CAMBP certifies Bee Ambassador, Apprentice, Journey, and Master level beekeepers so, according to the website, "they can effectively communicate the importance of honey bees and other pollinators within their communities, serve as mentors for other beekeepers, and become the informational conduit between the beekeeping communities throughout the state and UCCE (Cooperative Extension staff)."
CAMBP Master Beekeeper Sung Lee of Castro Valley, known worldwide on social media as "Sung Lee The Bee Charmer," provided an observation hive. Throughout the festival, his queen bee laid eggs as attendees excitedly asked questions and captured images. Lee said he purposely did not mark the queen so folks would look for her. "When there were more than five in a crowd, I offered one dollar to whoever finds the queen in 30 seconds," he related. And then he told them: "If you don't, everyone pays me one dollar!"
"I learned that in comedy class!" he quipped.
Wrlter Jason Laurenzano profiled him in Passions Illustrated in a Dec. 31, 2020 piece titled Sung Lee, The Bee Charmer. Laurenzano described him as "a 62-year-old Korean-born naturalized U.S. citizen who owns and operates a pair of successful and award-winning dry cleaning businesses." In his childhood, Sung trained as a speed skater and figure skater.
"In 1982, at the age of 23, he opened Hesperian Cleaners, Inc. in San Lorenzo, California," Laurenzano wrote. "He later opened a second location in the nearby town of Danville. Both are successful not only economically but also in terms of environmental responsibility. His was the first to convert to green technology in Alameda County, replacing toxic cleaning solvents with a technology known as 'Professional Wet Cleaning' that conserves water and energy and produces no hazardous waste." In 2011, Lee was inducted into the Hall of Fame of Environmental Business People and is featured in the regional "Legendary Locals" book.
Sung Lee says his interest in beekeeping originated with fruit trees on his property. Trained by the California Master Beekeeper Program, he went on to become a member of the board of directors of the Mount Diablo Beekeepers Association, "Beekeeper of the Year," and vice president. His fans include 2400 on Facebook (Sung Lee the Bee Charmer); 3100 on Instagram, and more than 4100 on TikTok (with 6.1 million likes).
UC Davis Award. CAMBP recently won a Faculty/Staff Partnership Citation of Excellence Award from the UC Davis Staff Assembly for "outstanding achievements and notable contributions" in disseminating science-based beekeeping information through a network of organizations and trained volunteers since 2016. Chancellor Gary May will present the award to Niño and co-program manager Wendy Mather at a fall reception on the UC Davis campus.
"The award seeks to highlight teams who actively develop and encourage faculty/staff partnerships and as a result are able to make notable contributions to UC Davis that contribute to the University's Mission of Teaching, Research, and Service; and who exemplify outstanding achievement and/or service," according to Staff Assembly officials. (Kian Nikzad serves as the co-program manager of CAMBP but as a new employee, was ineligible to be nominated)
Since 2016, CAMBP has:
- Given 32,000 hours of volunteer time (Beneficial Educational Experiences) and served 186,630 individuals in education, outreach and beekeeping mentorship. If a volunteer hour is worth $26.87, the program has given $859,840 back to the state of California in service of science-based beekeeping and honey bee health.
- Enrolled 185 Honey Bee Ambassadors (a level established in 2021), 494 Apprentice, 93 Journey level candidates and certified 20 Master level beekeepers. There are 12 members in 2023 participating in their Master Capstone projects.
- Since the team began tracking Continuing Education Experiences in 2020, they're recorded 3752 hours
- They're also working on updating a safety manual.
The California Honey Festival, launched in 2017, is the brainchild of the City of Woodland and Amina Harris, director of the UC Davis Honey and Pollination Center. It takes place annually in downtown Woodland. The 2024 celebration is scheduled May 4.
