Talk about the unexpected.
“Look!” says Jim.
He pauses by the kitchen counter.
"Over there!” he says, pointing. I don't see anything except the half-filled coffee pot.
Then I see it. "There," as in “over there,” is a praying mantis clinging to the wall and staring at us. It is like finding a grizzly bear in Kenya. (Yes, there is a grizzly bear in Kenya, on a private reserve, the Ol Jogi wildlife conservancy in Laikipia, Kenya)
Praying mantis expert Lohit Garikipati, entomology student at the University of California, Davis and an associate at the Bohart Museum of Entomology, identified our kitchen guest as a Stagmomantis limbata, a bordered mantis native to North America. “Looks like she wanted to come in for some free food!” Lohit quipped.
That's how we acquired Henrietta (which means home ruler) . Apparently she hitched a ride on the back of Jim's jacket as he was removing a patch of Mexican sunflowers. She opted to depart her "ride" in our kitchen.
By the half-filled coffee pot. Praying mantids don't do coffee.
We placed Henrietta in an aquarium, screened at the top, and kept her for a week, feeding her drone flies and crickets. We provided her with an upright stick just in case she wanted to deposit an egg case, an ootheca.
Several days later an ootheca, about an inch long, appeared in the aquarium. Not on the stick—she chose to deposit it on the floor.
What does an ootheca look like under a powerful microscope? Amazing. Lynn Epstein, UC Davis emeritus professor of plant pathology, photographed it with a Leica DVM6 microscope owned by the Department of Pathology and the College of Agricultural and Environmental Sciences (see below).
She hides 'em and we seek 'em.
We've spotted as many as seven adult praying mantids at a time in our little pollinator garden in Vacaville, Calif., but never once have we seen any of them laying eggs.
The praying mantis lays an egg mass known as an ootheca or a protective egg sac. But always when you're nowhere around!
Not so this time.
Late Sunday afternoon, Sept. 23, Ms. Mantis (a Stagmomantis limbata, as identified by UC Davis student Lohit Garikipati, a Bohart Museum of Entomology associate who rears mantids) decided to grace our milkweed planter with a little present.
She climbed a redwood stake, looked around, saw me (oh, no problem, you're not a predator!), and crawled over to the other side. She positioned herself upside down, bulging abdomen intact, and proceeded to do her business. A frothy cream-colored substance began to emerge. (See my short YouTube video.) When darkness fell, she was still there.
When Monday dawned, she was still there, her ootheca finished and hardening. It probably contains several hundred eggs, but who's counting? However, scientists estimate that only one fifth will survive to adulthood. Many of the nymphs will be eaten by their hungry brothers and sisters. Bon appétit?
"Now that she's deposited the ootheca, will she expire soon?" we asked Garikipati.
"It's still early on in the season, so she may lay another two or three," he said.
She may indeed. Mama Mantis continues to hang out in the milkweed, while her ootheca, like a flag on a flag pole, "commemorates" the spot.
It should be a warning sign to incoming monarchs.
The next day, we found the clipped wing of a male monarch.
Judge: "Will the defendant please rise?"
The defendant, a praying mantis--a male Stragmomantis limbata--rises solemnly, stretching his spiked forelegs.
Judge: "Do you have anything to say for yourself about how this dismembered Gulf Fritillary butterfly, Agraulis vanillae, happened to be in the very same passionflower vine that you were occupying--at the very same time, 4 p.m., Sept. 12, 2018 in Vacaville, Calif.? Do you have anything to say for yourself, Mr. Mantis?"
Defendant: "Yes, sir! I do, sir. I was hungry. But I ate only the abdomen, thorax and head. I left the pretty parts, the wings, behind, for everyone to enjoy."
Mystery solved. Everybody eats in the pollinator garden!
The male Stagmomomantis limbata, as identified by mantis expert and Bohart Museum of Entomology associate Lohit Garikipati, a UC Davis entomology major who rears mantids, proved difficult to see amid the green passionflower vine (Passiflora). A perfect camouflage!
It's a male Stagmomomantis limbata and not a male Mantis religiosa? "Note the bicolored pronotum (first thoracic segment) that is an easy distinguishing tool!" Garikipata said. "Mantis religiosa also have a band around the head!"
S. limbata, commonly called a "bordered mantis," is native to North America. It is green or beige and can reach three inches in length.
"Males are slender, long-winged, and variable in color, but most often green and brown with the sides of the folded tegmina green and top brownish (may be solid gray, brown, green, or any combination of these)," according to Wikipedia. "Abdomen without prominent dark spots on top. The wings are transparent, usually with cloudy brownish spots on outer half."
Garikipata described it as a "super cool find, adult males are superb fliers!"
This one didn't fly. At least then.
Neither did his prey, the hapless Gulf Fritillary.
(Editor's Note: The Bohart Museum of Entomology, directed by Lynn Kimsey, professor of entomology at UC Davis, will host an open house, "Crafty Insects," from 1 to 4 p.m., Saturday, Sept. 22 in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis campus. The public event--free and family friendly--will focus on "crafty" or "sneaky" insects. Visitors are invited to bring insect crafts that they have made. They will be displayed next to "crafty" or "sneaky" insects.)
Well, UC Davis officials and the UC Davis Department of Entomology and Nematology did!
All systems are "go" for the 104th annual UC Davis Picnic Day, an all-day event on Saturday, April 21 when scores of visitors, aka picnickers, will stroll the campus. It promises to be both educational and entertaining.
The UC Davis Picnic Day Committee offered a pre-view Thursday noon at the Quad.
Bohart Museum of Entomology representatives--Wade Spencer, Lohit Garikipati, and Diego Rivera, all UC Davis students and Bohart associates--kept busy answers questions about scorpions, stick insects and praying mantids.
Spencer displayed his desert hairy scorpion named Celeste. Okay, surprise, surprise! Celeste turned out to be a male, but his name remains Celeste.
Lohit Garikipati, an entomology student who rears praying mantids, came with his buddy, a Malaysian shield mantis. "What's that?" visitors asked, looking at the shield.
For a hour, the trio entertained the guests. Some expressed awe at Spencer casually holding a scorpion. "I've been handling scorpions since I was three," he said. "I've never been stung."
Rivera showed an Australian leaf walking stick insect that resembled a leaf. The crowd took turns holding and photographing it.
Now it's showtime!
On Saturday, April 21, during the campuswide Picnic Day, you can engage with insects at both Briggs Hall, which houses the Department of Entomology and Nematology administration and most of the faculty, and the Bohart Museum of Entomology, home of eight million insect specimens.
At Briggs Hall, located off Kleiber Hall Drive, activities will take place from 9 a.m. to 4 or 5 p.m. At the Bohart Museum of Entomology, located in Room 1124 of the Academic Surge Building on Crocker Lane, the open house is from 10 to 3 p.m.
Here's what's on tap at Briggs, either in front or inside the building:
- Entomology at UC Davis: Enter Briggs Hall and find a wide variety of entomology-themed displays, from classics, including insect forestry to recent additions, such as “Virtual Reality Bugs."

The band, dressed in insect costumes, will include Jackson Audley of the Steve Seybold lab, rhythm guitar; Yao Cai of the Joanna Chiu lab, drums; Christine Tabuloc of the Chiu lab, vocals; Zachary Griebenow of the Phil Ward lab, keyboard; Wei Lin of the Brian Johnson lab, bass; Jill Oberski of the Phil Ward lab, tenor saxophone; and Brendon Boudinot of the Phil Ward lab, bassist.
"The band will be setting up and warming up at 4," said Boudinot. "We'll start our set at 4:30, and wrap up at 5 or so. We are working on tightening up the set list--for now we have four songs. Expect some guitar and drum solos at the least!"
At the Bohart Museum, open from 10 a.m. to 3 p.m., the theme is "Where the Sun Doesn't Shine," a play on this year's Picnic Day theme of "Where the Sun Shines."
"We'll be highlighting nocturnal insects, cave dwelling insects, and yes, beaver butt beetles or Platypsyllus castoris, an ectoparasite on beavers, near their glands, wounds, and skin," said Tabatha Yang, education and outreach coordinator. " We will be holding insects as well."
The Bohart Museum will also showcase its live "petting zoo," comprised of Madagascar hissing cockroaches, walking sticks or stick insects, tarantulas and mantids. The museum also offers a year-around gift shop with T-shirts, jewelry, posters, books, insect nets and the like.
"Entomology at UC Davis" (122 Briggs) has been nominated for a special campus award under the category "At One With Nature." The Honey Tasting booth at Briggs has been nominated for a similar award under the category, “Hunger Fix.” Winners of the categories are determined by an Internet vote. (Access the link here to vote from 8 a.m. to 10 p.m. for your favorite exhibits on Picnic Day). The winners will be publicized on the Picnic Day website, Facebook, Twitter, Instagram, and Snapchat accounts after Picnic Day.
What's a picnic without bugs?
Have you ever said "Hi" to a watermelon?
No? Well, you can "meet and greet" a watermelon at the Bohart Museum of Entomology during the seventh annual campuswide Biodiversity Museum Day on Saturday, Feb. 17 at the University of California, Davis.
But you can't thump it.
It's a praying mantis nicknamed "Watermelon," so named because of its red and green coloration.
The adult female Australian rainforest mantis, Hierodula majuscola, is part of the collection of UC Davis entomology student/Bohart Museum associate Lohit Garikipati.
Garikipati will be showing Watermelon and numerous others from his collection--including an orchid mantis named Marsha--from 9 a.m. to 1 p.m. at the Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane.
"Watermelon is actually on the smaller size of her species--wild individuals are more around the 4-5 inch mark, whereas watermelon just passes 3 inches," says Garikipati, who serves as secretary of the UC Davis Entomology Club and is an active member of the Facebook page, Mantis Keepers. "They are incredibly aggressive, both males and females, and females will even regularly eat Extatosoma tiaratum (Australian leaf insects) when they come across them."
The Australian rainforest mantises are not only known for their large size and aggressive nature, but "they are very pretty, with black and red on their inner forearms--which they flash in defense when they are threatened, Garikipati points out. "So far Watermelon has laid two egg cases, "but this species can lay around four, with each ootheca hatching 150 plus nymphs."
Garikipati presented a detailed seminar on mantises last Friday to fellow scientists at the Bohart Museum during their regular lab meeting.
Also at the Bohart Museum on Feb. 17, you can see the butterfly and moth collection, curated by entomologist Jeff Smith; and newly collected specimens from a January field trip to Belize headed by Bohart associate and entomologist Fran Keller, assistant professor at Folsom Lake College; wildlife biologist Dave Wyatt, professor at Sacramento City College; and others on the field trip. No stranger to the Bohart, Keller received her doctorate in entomology from UC Davis, studying with major professor Lynn Kimsey, director of the Bohart.
The Bohart Museum is just one of 13 museums or collections to be showcased during the UC Davis Biodiversity Museum Day. The event is free and open to the public.
The following will be open from 9 a.m. to 1 p.m.:
