He's a male Mantis religiosa, as slim as a string bean, and scanning his environment.
We're accustomed to seeing see the native Stagmomantis limbata in our garden, and not M. religiosa, the European mantis, which is found throughout Europe, Asia, Africa, and North America.
"Males are often found to be more active and agile, whereas females are physically more powerful," according to Wikipedia. "Adult females are generally too large and heavy for their wings to enable a take-off...The great variation in the coloration of M. religiosa from different shades of yellow, brown, green, and sometimes black has been the cause of numerous hypotheses and studies for over 100 years.However, no generally accepted answer about reason, benefit, or mechanism of the coloration or the change of coloration has been found."
The male is apparently quite good at avoiding sexual cannibalism during mating. Wikipedia says: "Instead of just observing them, sexually mature males approach sexually mature females when they see them, but due to the physical superiority of the females, males of M. religiosa face certain challenges in doing so. When a female spots a male, she is very likely to attack and kill him (see also: Sexual cannibalism). Therefore, males can be observed to be very slow and cautious in their approach; after spotting a female, the male usually freezes and turns his head to look directly at her. Since the foveae in his eyes face directly forwards, he has the most accurate and detailed view of her and can watch every one of her moves. He then proceeds to approach her from behind. Males can be observed to stop as soon as the female turns her head or even moves. Mantids are very good at detecting moving structures, but are almost unable to see immobile objects. Using this ‘stop-and-go' tactic, the male stalks closer to the female. This can often take several hours. Depending on the environment, males sometimes show a light ‘rocking'-behavior which is believed to imitate the leaves of surrounding plants to blend in with the background. Males doing this had no higher probability of being detected and attacked, which supports this hypothesis of concealment."
We asked praying mantis scientist Lohit Garikipati about this European species. He holds a bachelor's degree from UC Davis and a master's degree from Towson University, Md., and is now PhD-bound at the Richard Gilder Graduate School in the American Museum of Natural History in the Jessica Ware lab.
"In my time at Davis I observationally did--they hold a special place for me as they were the first species that ever kept and raised in captivity!" said Garikapti, who shared his mantises and expertise at the Bohart Museum of Entomology open houses. "But they also highlighted to me the potential impact of invasive species on both native mantis species but also prey populations--as low foliage and ground dwelling predators, they have a different niche from S. limbata, and may be contributing to the decline of native Litaneutria (even as they have for the California mantis, Stagmomantis wheelerii). Adult females have also been observed feeding on fence lizards, without much apparent effort as they can take lizards even larger than they are. All of these factors combined with their cryptic ooth (ootheca) deposition and large clutch size have made them one of the most if not the most successful mantis species on the planet - they tolerate both cold and hot climates being found in deserts to temperate forests and now have a Holarctic distribution."
Garikipati related that in the Ware lab, he will be "investigating the evolutionary relationships of praying mantises and what drove their diversity."
We look forward to hearing more from Lohit! As for our buddy, the male M. religiosa, he took flight. (See video on YouTube).

UC ANR Fire Network compiles expert advice on preparedness, evacuation tasks
The explosive growth of the Park Fire in Northern California was fueled by recent, intense heat waves and extremely dry vegetation – conditions seen at many locations across the state.
Given the potential for wildfire and smoke impacts during what is expected to be a protracted “fire season,” California residents should think ahead and complete emergency preparations: https://ucanr.edu/sites/fire/Preparedness/.
“If you are concerned that you or someone you know could be affected by fire or smoke, now is the time to take simple steps to prepare,” said Yana Valachovic, University of California Cooperative Extension forest advisor for Humboldt and Del Norte counties.
Valachovic and other members of the UC Agriculture and Natural Resources Fire Network are urging community members to tackle small but significant tasks to minimize potential fire damage. Many of these tasks can be finished in a weekend, such as:
- Clean debris from your roof and gutters.
- Inspect the area around your home and nearby structures and remove all combustibles (dead grass, plants, woody mulch, stored wood, etc.) in the first 5 feet, including under decks and stairs.
- Inspect the foundation, under-eave, and gable-end vents for holes and damage; add a layer of finer metal-mesh screens (1/8” mesh) to the vents to prevent ember penetration.
- Inspect the garage door bottom seal to make sure embers can't blow under the door.
- Replace the first 5 feet of wooden fences that attach to buildings with a noncombustible panel or gate.
A recently published report, “Retrofitting a Home for Wildfire Resistance,” also can help residents prioritize the measures that are most cost-effective and fit their budget.
Six things to do, six hours before evacuation
As evacuation warnings are issued for local communities, there are six important things to do in advance of an actual evacuation order, according to Valachovic:
- Close windows, pet doors and skylights.
- Move inside patio cushions, brooms and door mats; tie open wooden gates that attach to the house or deck to prevent a fire from traveling from the fence to the house.
- Relocate the barbecue propane tank away from home.
- Stage buckets of water and garden hoses in visible locations.
- Dress for evacuation: cotton clothes, sturdy shoes, hat and face protection and leather gloves.
- Put your “go bag” in your vehicle.
The UC ANR Fire Network website also includes downloadable checklists – in English and Spanish – for your go bag (https://ucanr.edu/sites/fire/Safety/Evacuation/Preparing_a_Go-Bag/) and for a host of important pre-evacuation tasks for your household, property, pets and livestock (https://ucanr.edu/sites/fire/Safety/Evacuation/).
“We want communities to be wildfire-prepared – not scared,” Valachovic emphasized.
Smoke exposure a significant public health concern
Hazardous smoke can blanket wide swaths of California – and much of the Western U.S. – during ongoing wildfire events. A primer on harmful health effects, a list of tips for reducing smoke exposure, and other resources and links can be found on the UC ANR Fire Network site: https://ucanr.edu/sites/fire/Safety/Air_Quality_and_Smoke/.
“If there's smoke in the forecast for the next few days, I would keep an eye on my local air quality at fire.airnow.gov,” said Katie Low, statewide coordinator for UC ANR's Fire Network. “And if the AQI – Air Quality Index – is high, I would limit my outdoor activity, wear an N95 mask if I do go outside, and run my air purifier.”
For instructions on making a DIY air cleaner, creating a “clean air space” in your home and fitting an N95 mask properly, visit the California Air Resources Board's “Smoke Ready California” page: https://ww2.arb.ca.gov/smokereadyca.

Born in Tonbridge, England, but a resident of Canada since 1945, Jeremy received his bachelor's degree in zoology, with honors, from the University of Western Ontario in 1969, and his doctorate in entomology and ecology from North Carolina State University in 1972. He served as a professor at Western Ontario from 2004 until his death.
"Jeremy died as he lived, tenacious and determined to the last--qualities that served him well as he blazed a trail through life," according to his obituary in Legacy.com. "He was recognised internationally as an eminent research scientist, publishing hundreds of papers, holding many positions of distinction and receiving countless accolades and awards. These include, among many others, President of the Royal Society of Canada, the Humboldt Research Fellowship in Germany, and the Order of Canada for his services to education. He was a passionate and enthusiastic educator his whole life, an ambassador equally at ease with everyone from VIPs to children."
"He received several national awards for his outreach activities, often saying the publication that he was most proud of was What is an Insect?, a children's book he co-wrote with Let's Talk Science which has been translated into five languages, and is used as a teaching aid in schools across Canada."
The professor, fondly nicknamed "The Bug Man," treasured his 500 (plus) insect-themed T-shirts, his favorite attire. One of them was "The Beetles," the all-time best seller designed and sold by the UC Davis Entomology Graduate Student Association. Mimicking The Beatles (George Harrison, Paul McCartney, Ringo Starr and John Lennon) crossing Abbey Road in a single file, the t-shirt depicts four beetles sauntering across the road. Beneath each beetle image is the family name: Phengogidae, Curculionidae, Cerambycidae and Scarabaeidae. Think glowworm beetles, snout beetles, long-horned beetles and scarab beetles.
"If you look closely," we wrote in a Bug Squad blog posted Dec. 4, 2023, "these UC Davis beetles are all wearing clothes--maybe designer clothes designed just for them? Three are barefoot, and one, the long-horned beetle, is wearing shoes. EGSA records don't indicate who designed The Beetles, but it's a keeper. It never fails to draw smiles. (EGSA sells this t-shirt and others at https://ucdavisentgrad.square.site.)
But back to Jeremy O'Neil and his love of insect-themed T-shirts. On July 26, his friend and colleague, UC Davis distinguished professor Walter Leal, recently elected a member of the National Academy of Sciences, posted an image on X (formerly Twitter) of McNeil wearing his UC Davis Beetles T-shirt. "Jeremy McNeil (Nov. 20, 1944 – July 18, 2024) had 500+ entomology-themed T-shirts, but this is--without a doubt--the number one! I am slightly biased because I like beetles in the family Scarabaeidae, not because I'm a @ucdavis faculty of course."
According to Legacy.com, all of McNeil's t-shirts will be "catalogued and sold to raise money for charity."
Jeremy Nichol McNeil would have loved that--but maybe not quite as much as he loved entomology and inspiring others to learn about insect science.

Quickly planting trees after wildfires crucial for communities, ecosystems, carbon goals
As the climate crisis fuels more high-severity wildfires, many forests – adapted to bounce back from frequent but less-intense fires – are struggling to recover quickly.
“In a lot of locations, forests in the Sierra Nevada that burn at high severity are not regenerating on their own,” said Susie Kocher, University of California Cooperative Extension forestry and natural resources advisor for the Central Sierra. “They need to have living trees to drop seeds; if everything dies in an intense fire, then there's a high likelihood in those locations that trees might not return for a while.”
According to Kocher, a forest may take multiple decades to grow back on its own, seeding in very slowly from the edges of a burn. To speed up that regeneration process, a pilot program of local “Emergency Forest Restoration Teams,” or EFRTs, have been helping forest landowners rapidly remove dead trees, plant new seedlings and expedite other vital tasks after wildfires.
Kocher is a co-author of a recently released report evaluating the EFRTs, which appear to be effective in assisting often-overwhelmed private landowners navigate competitive funding programs and complicated permitting pathways after wildfire. Small private landowners in California own 7 million acres, comprising 22% of forested land across the state.
“None of our current assistance programs were really designed to rapidly respond to high-severity fire disasters,” Kocher said. “And we're just getting so much more high-severity fire now that there needed to be a different way of helping people, besides business as usual.”
Lead agencies improve coordination of restoration efforts
Drawing from a successful model in Washington, Kocher and other members of the Governor's Forest Management Task Force recommended the formation of EFRTs in 2019 and this recommendation made it into the California Wildfire and Forest Resilience Action Plan of 2021.
Following the Caldor, Dixie and Tamarack fires during that year, disaster relief funds from CAL FIRE and the U.S. Forest Service enabled the establishment of pilot EFRTs in each of the affected regions. A key innovation was designating a local lead agency to coordinate restoration efforts: the El Dorado Resource Conservation District (Caldor), the Feather River Resource Conservation District (Dixie) and Alpine County (Tamarack).
“The idea is that one well-established local agency gets the funds to carry out all the reforestation work,” Kocher said. “They find contractors for the landowners and plan and carry out all the work needed, including dead tree removal, site preparation and replanting; this helps it be more coordinated across the landscape and reduces competition for contractors.”
“Also, for most of that work, there's no cost to the landowner – which is a huge benefit to them, because these things can get really expensive, like many thousands of dollars an acre,” Kocher added.
Although there was an initial steep learning curve for the local lead agencies on the complexities of reforestation and the maze of required permits, they quickly executed a significant number of forest restoration treatments. Within two years, the three pilot teams had collectively completed over 2,500 acres of dead tree removal and 1,400 acres of conifer planting.
“The overwhelming benefit of the pilots was that a lot of work got done on the ground, that otherwise would not have been done – at least not in the timeframe that was made possible by the EFRTs,” said Daylin Wade, a UCCE staff research associate and co-author of the recent report, who synthesized feedback from interviews of professionals involved in the program.
Rapid reforestation better financially, ecologically
Both Wade and Kocher underscored how the EFRTs were crucial in completing restoration tasks in a timely manner. Removal of dead wood becomes trickier and more expensive over time, as the trees decay and are dangerous to cut down.
“A major accomplishment was getting trees out of there while it was both safe and economically viable to remove those trees – and getting trees in the ground before shrubs dominate the site,” Wade explained.
It's also imperative to quickly remove the dead trees to reduce the fuel load and minimize the chances of re-burn in the area.
“If you're not doing this work, then you're actually endangering the investment that you're putting into rebuilding communities that burned, because they're in danger of burning again if you have huge piles of dead trees everywhere,” Kocher said.
Furthermore, expediting those tasks helps restore the forest cover that is crucial for sequestering carbon and achieving the goals of California's sweeping climate action plan – such as attaining carbon neutrality by 2045.
“We have very ambitious carbon goals for our forests in California, and so reestablishing them – even on private lands – is a public benefit,” Kocher said.
Evaluation of EFRTs by UC Cooperative Extension continues
In addition to enumerating the progress of the three EFRT case studies, the evaluation report also lists recommendations to further enhance the program, such as securing rapid and flexible funding for future EFRTs, improving guidance for local lead agencies and streamlining permitting processes.
The authors also stressed the need to expand opportunities for the commercial sale of woody material in the aftermath of a wildfire event. Selling logs and wood chips reduces the volume of material that would need to processed onsite by the EFRTs and their contractors, thereby defraying some of the costs for that work.
But there simply hasn't been a sufficient market for that woody biomass.
“It's a big barrier,” Kocher said. “If we had a healthier timber market, it would be easier to make this stuff pay its own way and be less of a subsidized endeavor.”
UC Cooperative Extension's EFRT evaluation work – made possible by funding from the U.S. Forest Service State, Private and Tribal Forestry, Region 5 – will continue for the next couple years. On the heels of this first report, Wade will next gather and summarize feedback from private landowners on whether the EFRTs are meeting their goals.
And, later this summer and fall, researchers will begin assessing the ecological success of the plantings in the restoration areas, surveying seedling survival and gauging the volume of competing vegetation.
“It's hugely encouraging that we've gotten all these trees in the ground, but it's not the end of the process – it's just the beginning,” Kocher said. “Trees and forests need to be maintained over time, so this next step will let us see how successful that has been, and if there are additional steps needed to actually ensure that these trees succeed and thrive.”

The Vacaville Museum Guild's annual children's party--for Vacaville children ages 3 to 9--promises to be a honey of a party.
Themed "Fun on the Farm," it's an entertaining and educational event set for 10 a.m. to 12:30 p.m., Thursday, Aug. 8 in the museum courtyard, 213 Buck Ave.,Vacaville.
Coordinators Pamela King and Diana McLaughlin said the children's party will include a walk-around Queen Bee handing out honey sticks, and a real "Queen Bee"--Ettamarie Peterson of Petaluma, known as the Queen Bee of Sonoma, who will display a bee observation hive. Another Queen Bee, Amina Harris, has donated honey sticks.
The event also will include 4-H animals, a walk-around Mother Goose, face-painting, and a ring toss with a hobby horse named Trigger. The youngsters will create sand art jars, craft paper crowns, plant seeds in a take-home container, and pose for photos behind a UC Davis Bohart Museum of Entomology California dogface butterfly cutout banner. The menu, free with the $3 admission, includes hot dogs, popcorn, chips, cookies and water. Tickets can be purchased only at the museum on Thursdays through Saturdays between 1 p.m. and 4:30 p.m.
Capsule information:
Ettamarie Peterson. She's a retired teacher, a longtime beekeeper, a 4-H beekeeping leader and a great-grandmother who loves to talk about bees and show her bee observation hive at schools and special events. She'll point out the queen bee, worker bees and drones and discuss their roles. “I started beekeeping before I retired in 1998 from 37 years of teaching,” Peterson says. She has served as president and treasurer of the Sonoma County Beekeepers' Association (SCBA) and edits the SCBA newsletter, The Monthly Extractor. She collects swarms for her Liberty 4-H Club beekeepers. "I got involved in 4-H when my son wanted his daughters to learn how to keep bees. They are both parents now so I am hoping to teach the three great-grandsons, too!"
Peterson is also a longtime friend and supporter of UC Davis. She delivered a tribute to the late Eric Mussen (1946-2022), a 38-year California Cooperative Extension apiculturist and member of the Department of Entomology and Nematology faculty.
Queen Bee Costume. The queen bee costume is from the UC Davis-based California Master Beekeeper Program (CAMBP), founded and directed by apiculturist/bee scientist Elina Lastro Niño, associate professor of UC Cooperative Extension, and a member of the faculty of the Department of Entomology and Nematology. CAMBP is "a continuous train-the-trainer effort," the website explains. "The CAMBP's vision is to certify Honey Bee Ambassador, Apprentice, Journey, and Master level beekeepers so 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 (UC Cooperative Extension) staff." Program managers are Wendy Mather and Kian Nikzad.
Honey Sticks. The wildflower honey sticks were donated by Amina Harris, founding director of the UC Davis Honey and Pollination Center who retired last year to return to her family business, Z Food Specialty and The HIVE, 1221 Harter Ave, Woodland. The Hive is known as the largest honey and mead tasting room in California and is newly featured in Travel and Leisure. A community gathering place, The Hive "aims to educate and engage visitors in varietal honeys, mead, honey bees, and pollinators." A honey-inspired menu features local and seasonal farm-to-fork foods. A pollinator garden and musical presentations are also draws. Amina's husband, Ishai Zeldner (he passed in 2018 at age 71), founded the business. Amina serves as the Queen Bee; son, Josh Zeldner is the nectar director, and daughter, Shoshana Zeldner, is the director of brand strategy. See more about the family and its business here.
Be a Butterfly. Attendees will pose for pictures behind the cut-out California dogface butterfly banner from the Bohart Museum. They also will see Bohart associate Greg Kareofelas' macro images of the egg, caterpillar, chrysalis and adult. The California dogface butterfly, Zerene eurydice, is the state insect, as designated by State Legislature in 1972. The butterfly is found only in California from the foothills of the Sierra Nevada to the Coast Ranges and from Sonoma south to San Diego. Its habitat also includes Gates Canyon, Vacaville. The male butterfly, which sports a yellow silhouette of a dog's head on its wings, is known as "the flying pansy." The female is mostly solid yellow except for a single black spot on its upper wings.
