Hide and seek.
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.
We know that a praying mantid lays her eggs in 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.
"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.
Eager hands cradling an orchid mantis.
Eyes darting toward a hornet's nest.
That set the scene at the UC Davis Bohart Museum of Entomology's three-hour open house, themed "Crafty Insects." Visitors learned about the sneaky or cunning insects like praying mantids, and about the skillful insects such as hornets that construct intricate nests of wood pulp and saliva.
Entomologist Jeff Smith, who curates the butterfly and moth section of the Bohart, loaned the quilted dragonfly hanging, the work of his mother-in-law, quiltmaker/seamstress Ann Babicky of Schofield, Wis. "She made it personally with us in mind," he said.
UC Davis entomology student and Bohart associate Lohit Garikipati, who rears mantids, loaned some of his favorites, including an orchid mantis, Hymenopus coronatus, a shield mantis, Rhombodera valida, and an Asian dead leaf mantis, Deroplatys truncata.
Garikipati, who serves as secretary of the UC Davis Entomology Club displayed mantids and walking sticks with club president Chloe Shott.
Smith and Bohart associate Greg Kareofelas showed visitors the moth and butterfly collection, while UC Davis student Emma Cluff answered questions about a hornet's nest. Another UC Davis student, Isabelle Gilchrist, staffed the "paint-a-rock" table. (See Bug Squad blog). Tabatha Yang, the Bohart's education and outreach coordinator, coordinated the open house.
Located in Room 1124 of the Academic Surge Building on Crocker Lane, it houses
- nearly eight million insect specimens
- the seventh largest insect collection in North America
- the California Insect Survey, a storehouse of the insect biodiversity
- a live "petting zoo," comprised of Madagascar hissing cockroaches, walking sticks, tarantulas and praying mantids; and
- a year-around gift shop, which is stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy
The Bohart Museum's regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. It is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free.
Public weekend hours for the academic year 2018-2019 are:

- Saturday, Feb. 16, times vary: (campuswide) Biodiversity Museum Day
- Saturday, March 9, 1 to 4 p.m., "Eight-Legged Wonders"
- Saturday, April 14, 10 a.m. to 3 p.m., (campuswide) UC Davis Picnic Day
Talk about "crafty"--as in cunning or sneaky--insects.
Ever seen a praying mantis ambushing a cabbage white butterfly?
Or an assassin bug targeting a spotted cucumber beetle?
Or European paper wasps attacking a Gulf Fritillary butterfly?
And, how about the other kind of "crafty" insects--like honey bees and European paper wasps creating those intricate nests?
"Crafty Insects" will set the theme for the Bohart Museum of Entomology's open house from 1 to 4 p.m., Saturday, Sept. 22 in Room 1124 of the Academic Surge Building on the UC Davis campus. The event is free and family friendly.
“We are hoping to have two parallel exhibits--one where we show crafty insects and then one where we are asking people to bring insect-themed crafts from their home--a plate with a cicada on it, or mug shaped like a wasp or we have a bee-shaped stapler for example,” said Tabatha Yang, education and outreach coordinator. “We'll have a place for them to display their crafts.”
“Crafty insects can be interpreted in two ways,” Yang commented. "‘Crafty' can be makers such as caddis fly larvae, case bearer moths, and potter wasps. The other crafty interpretation is sneaky, so our live orchid mantid, the dead leaf butterfly like Kallima inachus will be on display.” Activities are to include “spot the flower fly versus bee activity” and “spot the assassin fly versus bumble bee activity.”
For the family crafts, visitors will be painting rocks that can be hidden on campus or elsewhere. The Bohart Museum officials were inspired by Yolo Rocks and Solano Rocks, but a similar organization on campus, UC Davis Rocks, launched a similar activity last spring. It is the brainchild of Kim Pearson and Martha Garrison, who work in the arts administrative group in the College of Letters and Science.
Saturday, Sept. 22 is also move-in weekend for UC Davis students, so the Bohart Museum expects a lot of new people exploring the campus.
Bohart associates Jeff Smith, curator of the butterfly and moth exhibit and naturalist-photographer Greg Kareofelas will be on hand to shows the collection.
The Bohart Museum, directed by Lynn Kimsey, professor of entomology at UC Davis, houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. In addition to the petting zoo, the museum features a year-around gift shop, which is stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
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.

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.)
The three men pause in front of the Kate Frey Pollinator Garden at the Sonoma Cornerstone and begin to read the sign.
"The Pollinator Garden by Kate Frey," one man reads out loud. "It's brand new, come back soon and watch as it grows. This flower-filled and colorful garden is a pollinator garden. All the plants offer food resources of pollen and nectar for pollinators such as native bees, honey bees, butterflies, hummingbirds and beneficial insects. Pollen is a protein, mineral and fat source and is primarily a larval food for bees, while nectar is composed of various sugars and is the main food for pollination and the adult life stage of many beneficial insects."
They watch the bees, butterflies and hummingbirds--buzzing, fluttering and swooshing--in a rush of colors.
"Beautiful garden," one says.
"Do you want to see a praying mantis?" I ask.
I had earlier spotted a mantis in the vegetation--a female Mantis religiosa (species identified by praying mantis expert Lohit Garikipati, a UC Davis entomology student who rears mantids).
Californians commonly see native mantids, Stagmomantis limbata and Stagmomantis californica, as well as this introduced one, M. religiosa.
"I don't see it," one of the men says. "Where is it?"
"There," I point. "Camouflaged."
"You have a good eye," he comments. "Wow, I haven't seen a praying mantis since I was a kid." He whips out his cell phone for a quick image.
The praying mantis made his day.
It's always a good day when you encounter a praying mantis.
Kate Frey, a resident of Hopland, is the author of the award-winning book, The Bee Friendly Garden, with Professor Gretchen LeBuhn of San Francisco State University, a book that details how to design an abundant, flower-filled garden that nurtures bees and supports biodiversity. She's a two-time gold medal winner at the Chelsea Flower Show and co-founder of The American Garden School. (Read this Bug Squad post to learn her favorite plants and how to attract pollinators.)
As Frey told the crowd at the 2018 UC Davis Bee Symposium, hosted last March by the UC Davis Honey and Pollination Center and the UC Davis Department of Entomology and Nematology: "Whether you plant them, nurture them, or walk through them, bee gardens make us happy."
They do, indeed. Praying mantids do, too.
