It's BYOM at the Bohart Museum of Entomology today (Sunday, Aug. 27).

That's “Bring Your Own Mantis.”

The open house, themed "Praying Mantises," is set from 1 to 4 p.m., in Room 1124 of the Academic Surge Building, 455 Crocker Lane. It is free and family friendly.

 “Bring a live praying mantis to show and share--and to bring back home--and have your name entered into a raffle for a Bohart t-shirt of your choice!” announced Tabatha Yang, education and outreach coordinator. “The mantis can be a purchased pet or one you found outside.” 

The Bohart Museum of Entomology, founded in 1946 and directed by UC Davis distinguished professor LynnKimsey, houses a global collection of eight million insect specimens; a live petting zoo, including Madagascar hissing cockroaches, stick insects and tarantulas; and an insect-themed gift shop, stocked with books, posters, collecting equipment, t-shirts, hoodies, jewelry and more. More information is available on the website https://bohart.ucdavis.edu/ or email bmuseum@ucdavis.edu.

How much do you know about praying mantises?

The Bohart Museum of Entomology is hosting an open house, themed "Praying Mantises," on Sunday, Aug. 27 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. It is free and family friendly. 

When asked what's fascinating about praying mantises, Lohit Garikipati, UC Davis entomology graduate (bachelor of science degree, 2019) wrapping up his master's degree with biologist Christopher Oufiero at Towson University,Towson, MD, said:

"What's fascinating about them... hard to pick just one thing! If I had to choose it would be their general awareness about the environment they are in. They are always watching, always waiting, and adjust their posture, behavior, and movement based on various environmental stimuli. They engage in some of the most interesting predatory behaviors; pouncing, lunging, spearing (yes, spearing!) and sometimes throwing themselves off of perches to secure potential prey. Few flightless predators can catch prey out of the air on the wing but many specialized species are more than capable of doing so. They are the insect equivalent of cats in many ways, but with some weird adaptations!"

Garikipati, who participated in many Bohart Museum open houses while a student at UC Davis, won't be at the open house on Aug. 27 but he will be their spirit. He plans to obtain his doctorate in entomology.

According to Kris Anderson of Las Vegas, an alumnus of Cornell University (master's degree in entomology) and author of Praying Mantises of the United States and Canada: "There are just 28 species of Mantodea found within the United States and Canada, the 7 largest of which are invasive species from other parts of the globe."

Some myths about praying mantises, as related by Anderson in his book, available on Amazon: 

Myth: "Mantises sway back and forth while crawling to imitate vegetation blowing in the wind."

Truth: "The peering movement of mantises, demonstrated by the swaying back and forth of their body while ambulating or preparing to leap/take flight, is a behavioral adaptation to gain depth perception of their surroundings and has nothing to do with mimicry. Mantises blend into their environment by remaining motionless against a substrate that they morphologically resemble—not by moving. Peering movements causes the retinal images of nearby objects to be displaced more quickly than those of more distant objects, thus allowing the mantis to gain depth perception of its environment as it navigates forward."

Myth: "Mantises grab insects and immediately bite the neck/head to quickly kill their prey."

Truth: "The spinose forelegs of praying mantises are used to hold onto and prevent their prey from escaping. Once secured in their grip, the mantis will pull the prey forward and begin to meticulously chew upon whatever body part of the prey item is closest to their mouth—be it a leg, a wing, the thorax, abdomen, or head. No specific body region is exclusively targeted and the prey is always eaten alive, bit by bit, dying a slow death."

Myth: "Female mantises cannibalize the males while mating."

Truth: "With over 2,400 species of Mantodea worldwide, only a small fraction of species regularly engage in sexual cannibalism. Most do not. Of those that engage in this practice, the occurrence is not inevitable, as males typically escape and may mate with other partners."

The Bohart Museum, founded in 1946 and directed by UC Davis distinguished professor Lynn Kimsey, houses a global collection of eight million insect specimens, plus a live insect petting zoo (Madagascar hissing cockroaches, stick insects and tarantulas), and an insect-themed gift shop, stocked with t-shirts, hoodies, books, posters, jewelry and more.

The Bohart Museum is planning two other open houses this fall: 

Saturday, Sept. 23: Household Vampires

Saturday, Nov. 4: Monarchs

All open houses are free and family friendly. At each event, the focus is on a special theme, but there's also a family arts-and-crafts activity, announced Tabatha Yang, education and outreach coordinator.

The Bohart Museum of Entomology has scheduled three fall open houses: 

Sunday, Aug. 27: Praying Mantises

Saturday, Sept. 23: Household Vampires

Saturday, Nov. 4: Monarchs

The open houses, free and family friendly, take place from 1 to 4 p.m. in the insect museum, located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. Parking is free.

At each event, the focus is on a special theme, but there's also a family arts-and-crafts activity. Visitors can view insect displays and hold the Madagascar hissing cockroaches and stick insects from the live petting zoo.

The museum, founded in 1946, is directed by UC Davis distinguished professor Lynn Kimsey. It houses a global collection of eight million insect specimens. In addition to the petting zoo, it houses a year-around, insect-themed gift shop.

(More details are pending)

The Bohart Museum of Entomology will dedicate its open house, “Night at the Museum” (formerly known as “Moth Night”) to the late Jerry Powell, longtime director of the Essig Museum Entomology of UC Berkeley, and an international authority on moths. He died July 8 in Berkeley at age 90.

Powell was a Bohart Museum associate and a scientific collaborator, identifying scores of insects and attending many of the Lepidopterist Society meetings held there.

The open house, free and family friendly, is set from 7 to 11 p.m., Saturday, July 22 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus.

Plans call for scientists to set up their traditional blacklighting (ultraviolet or UV) display to attract moths and other night-flying insects. Bohart Research Affiliate John De Benedictus, a retired UC Davis Staff Research Associate, also known as "The Moth Man," usually heads the blacklighting project with several other scientists. De Benedictus received his master's degree in 1988 from UC Berkeley, studying with Powell. "I spent more time in the field with Jerry than any other grad student," he related. "I was privileged to be Jerry's student and lucky to have become his friend."

Jerry, born May 23, 1933 in Glendale, Calif., received his bachelor's degree in entomology at UC Berkeley in 1955 and his doctorate there in 1961. One of his most-read books, co-authored with Charles Hogue, is California Insects, Volume 44, published in 1980. The second edition, co-authored by Kip Will, Daniel Rubinoff and Powell and covering more than 600 species, was published in October, 2020.

Powell and Paul Opler (1938-2023) co-authored Moths of Western America, published in 2009.

In a tribute to Powell on its website, the Essig Museum posted in part:

"In his teen years he was heavily influenced by Charles 'Harbie' Harbison, who ran the Junior Naturalist Program at the San Diego Museum of Natural History, and sparked an interest in Jerry for butterflies and moths. Seeing his potential, Harbie recommended Jerry for the Entomology program at UC Berkeley, where he received his BS in 1955 and his PhD in 1961. While climbing through the ranks of Junior Entomologist (1961-62), Assistant Entomologist (1962-67), Associate Entomologist (1967-73), Entomologist (1973-94), Lecturer in Entomology (1964-69), Associate Professor (1969-73), and Professor (1973-94) at UC Berkeley, Jerry also became Curator (1972-2018) and Director (1993-1999) of the Essig Museum of Entomology (1972-1999) and Project Leader for the California Insect Survey (1963-1999). Although he retired as Director in 1999, Jerry remained a professor of the Graduate School until 2012 and maintained an active research program in Lepidoptera life histories and systematics until 2018, advising many students along the way. (See more on Essig website.)"

"Jerry's rearing program was the most extensive in the history of the study of New World Microlepidoptera," according to the Essig post. "For over 50 years he and his students processed more than 15,000 collections of larval or live adult Lepidoptera. Resulting data encompass more than 1,000 species of moths, through rearing either field-collected larvae or those emerging from eggs deposited by females in confinement. This total includes more than 60% of an estimated 1,500 species of Microlepidoptera occurring in California."

Powell gained international recognition when he detected the agricultural pest, the light brown apple moth, Epiphyas postvittana, in a ultralight (UV) trap on July 19, 2006 in his backyard in Berkeley.

In an email to colleagues on July 9, Peter Oboyski, executive director of the Essig Museum of Entomology, wrote: "With a heavy heart I am sad to report that professor Jerry Powell passed away this weekend. His contributions to our knowledge of California entomology, microlepidoptera, and insect life histories are inestimable, as is the value of the training he provided to his students. As one of those students, I am eternally grateful for the time, energy, and knowledge Jerry shared with me in the museum and the field."

"A consummate field biologist, Jerry's knowledge and interests were broad, allowing him to read landscapes and discover the most interesting and cryptic of species interactions," Oboyski noted. "This is well documented in over 220 publications, but also in the 60+ years of his field notes and rearing records that we are currently digitizing. He is the collector of over 400 holotypes of various insect orders, described over 170 species and 14 genera of moths, and honored by 41 patronyms. He also published papers on Hymenoptera, Coleoptera, Diptera, Dermaptera, and a Nematode. His legacy is impressive and will long be remembered."

Powell described himself as a "MothNut" on his vehicle license plate, and also displayed a sticker, "Larvae on Board."

The Bohart Museum, directed by UC Davis distinguished professor Lynn Kimsey, is the home of a global collection of eight million insect specimens; a live insect petting zoo; and a gift shop.
