It happened so quickly.
The monarch butterfly (Danaus plexippus) fluttered to the lantana for a sip of nectar when the unexpected happened.
A praying mantis, lying in wait, leaped high and grabbed it by its wings.
Unable to fly, the monarch struggled to right itself. The praying mantis kept its viselike grip.
At the time, I was focusing on the butterfly and didn't see the predator. When I saw the butterfly struggling, I walked over to it and lifted it out of the lantana, only to find a praying mantis attached to it.
The butterfly did not make it. The praying mantis, a female about to lay eggs, did. She will be shown at the Bohart Museum of Entomology's open house on Saturday, Sept. 21 from 1 to 4 p.m. and then released.
Theme of the Bohart open house is "Live at the Bohart!" Live? That's because the open house will feature live insects, such as cabbage white and Gulf Fritillary butterflies, Madagascar hissing cockroaches, walking sticks, a rose-haired tarantula and a “Harry Potter bug,” which is an amblypygid commonly known as a whip spider or tailless whip scorpion.
The Bohart, located on the UC Davis campus in Room 1124 of Academic Surge on Crocker Lane, formerly California Drive, is home to nearly eight million insect specimens, collected throughout the world.
At the open house, museum officials will tell you how to rear a cabbage white butterfly and other butterflies, such as Gulf Fritllaries. You can talk insects with director Lynn Kimsey; senior museum scientist Steve Heydon; public education/outreach coordinator Tabatha Yang, and others. The gift shop will be open for the purchase of t-shirts, jewelry, posters, books, insect nets and other items.
As for the praying mantis, on Saturday she will be freed to catch more prey.

Tabatha Yang and her six-month-old son, Karoo, were sitting on their lawn last Sunday at their West Davis home, when she saw red. Literally.
One minute they were enjoying the springlike weather, and the next minute his head was covered with bright red dots. Looking closer, she spotted a tiny insect in his eye, which she quickly removed.
Then her legs began to welt and itch.
They had just encountered no-see-ums, tiny Valley Black Gnats that feed on blood.
“The adults are emerging in large numbers now and need blood so residents need to beware of grassy areas that cover alkaline clay soils,” said Lynn Kimsey, director of the Bohart Museum of Entomology and professor entomology at UC Davis. “These insects are ferocious biters. Even though they don’t spread any diseases, they are sufficiently annoying to keep people indoors in some areas of California.”
The Bohart Museum is now fielding scores of calls and emails.
“These no-see-ums are smaller than fleas and have a supreme itch,” said Yang, Bohart Museum education and outreach coordinator, who knew immediately what they were.
The biting gnats are particularly troublesome along the west side of the Sacramento Valley, including Davis and Woodland. “They’re often in grassy areas, such as in parks and on golf courses on the west side of California’s Central Valley,” Kimsey said. “When the soil begins to dry and cracks develop, the adults emerge.” The complete life cycle from egg to adult takes about two years.
The no-see-ums (Leptoconops torrens) belong to the family Ceratopogonidae and are about 1/16-inch long. They are so tiny they could pass through window screens, but they don’t, Kimsey said. However, they can and do slip beneath loose clothing, unnoticed, to get a blood meal.
Like mosquitoes, only the female no-see-ums bite. The insects breed when the weather warms in the spring, usually in May and June, and they remain a pest for several weeks, Kimsey said. They need a blood meal to complete their reproductive cycle.
They also bite domestic and wild animals and birds.
The females inject saliva into the skin, which pools the blood just beneath the surface, resulting in a small red dot that becomes excruciatingly itchy. A single bite can welt into a one-or two-inch diameter spot, which lasts about two weeks.
Kimsey cautions people not to scratch the welts, as scratching makes the itchy bites last twice as long and can lead to infected sores.
To avoid being bitten, Kimsey recommends that you limit exposure by not sitting long in places where they are likely to occur, or where you’ve heard of problem areas. “Move quickly through the area.”
“Repellents,” she added, “aren’t effective against these flies.”

Saturday, May 11 is "Moth-ers Day" at the Bohart Museum of Entomology, University of California, Davis.
Moth-ers Day? Yes, moths have mothers, too!
The open house, free and open to the public, will take place at the Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis campus.
The focus is on moths, and moths of all sizes, shapes, colors and patterns will be displayed, said Tabatha Yang, education and outreach coordinator. Most moths are nocturnal--unlike butterflies which fly during the day.
(As an aside, moth lovers and citizen scientists will unite for National Moth Week, July 20-29. As the website says, "Moths offer endless options for study, education, photography and fun.")
The Bohart Museum, directed by Lynn Kimsey, professor of entomology at UC Davis, houses a global collection of nearly eight million insect specimens and is the seventh largest insect collection in North America.
Visitors can also discover the popular live insects in the "petting zoo": Madagascar hissing cockroaches and walking sticks.
The gift shop (yes, credit cards are accepted) includes t-shirts, jewelry, insect nets, posters and books, including the newly published children’s book, “The Story of the Dogface Butterfly,” written by UC Davis doctoral candidate Fran Keller and illustrated (watercolor and ink) by Laine Bauer, a 2012 graduate of UC Davis. The 35-page book, geared toward kindergarteners through sixth graders, also includes photos by naturalist Greg Kareofelas of Davis, a volunteer at the Bohart.
The book tells the untold story of the California dogface butterfly (Zerene eurydice), Keller said. Bauer’s illustrations depict the life cycle of this butterfly and the children who helped designate it as the California state insect. Net proceeds from the book sales go directly to the education, outreach and research programs of the Bohart Museum. In addition, the book can be ordered online at http://www.bohartmuseum.com/the-story-of-the-dogface-butterfly.html.
Bohart officials schedule weekend open houses throughout the academic year so that families and others who cannot visit the insect museum on weekdays can do so on the weekends. The Bohart’s regular hours are from 9 a.m. to noon and from 1 to 5 p.m., Monday through Thursday. The insect museum is closed to the public on Fridays and on major holidays. Admission is free.
The last open house of the academic year is from 1 to 4 p.m., Sunday, June 9. The theme: "How to Find Insects."
For further information on Moth-ers Day, contact Yang at email@example.com or (530) 752-0493.

Insects and Halloween just seem to go together.
What would Halloween be like without costumes depicting honey bees, ladybugs, butterflies, bumble bees, and just plain bugs?
And maybe a few termites, roaches, bed bugs and stink bugs tossed in for good measure?
The Bohart Museum of Entomology at the University of California, Davis, annually hosts two pre-Halloween open houses. One, sponsored by the Bohart Museum Society, is for donors, Entomology Department affiliates, and other invited guests. The other, hosted by the museum itself, is open to all as part of its education, teaching and public service mission.
Spiders--although not insects--are wildly popular at these functions. Spider decorations dangle from the ceiling and painted images adorn faces.
Among the most interesting "bug" costumes showing up at the Bohart last week: a monarch butterfly outfit donned by Maia Lundy of Davis Senior High School, an intern at the Bohart; and a black widow spider costume worn by Tabatha Yang, the museum's outreach and education coordinator. Tabatha and her husband, Louie Yang, assistant professor of entomology at UC Davis, are expecting their first child.

Another guest, carrying an insect net, creatively presented herself as a pinned specimen. (Back in 2010, graduate student Matan Shelomi dressed as Billy the Exterminator.)
The Bohart Museum, located at 1124 Academic Surge on Crocker Lane (formerly California Drive) will be open for more weekend open houses during the 2012-2013 academic year. These open houses are free and open to the public.
The schedule includes:
Sunday, Nov. 18, 1 to 4 p.m. Theme: "Insect Societies"
Saturday, Dec. 15, 1 to p.m. Theme: "Insects in Art"
Sunday, Jan. 13, 1 to 4 p.m. Theme: "Extreme Insects"
Saturday, Feb. 2, 1 to 4 p.m. Theme: "Biodiversity Museum Day"
Sunday, March 24, 1 to 4 p.m. Theme: "Aquatic Insects"

What's Mother's Day without moths?
Moth specimens and a fun caterpillar craft activity will highlight a pre-“Moth’er's Day” open house from 1 to 4 p.m., Saturday, May 12 at the Bohart Museum of Entomology, 1124 Academic Surge on California Drive, University of California, Davis campus. The event is free and open to the public.
You can learn about moths and make "caterpillars" from colorful “scrunched-up paper” and chopsticks, says Tabatha Yang, education and outreach coordinator.
Might make a good Mother's Day gift, yes?
Entomologist and museum associate Jeff Smith will show visitors a “behind-the-scenes” look at the Bohart’s moth collection.
The Bohart Museum also features a year-around live “petting zoo” with such permanent residents as walking sticks, Madagascar hissing cockroaches, and a rose-haired tarantula. You can photograph them cradling in your hand or crawling up your arm.
In addition, the gift shop will be open so visitors can buy Mom such gifts as insect-themed jewelry, candy, T-shirts, sweatshirts, coffee mugs, and posters, as well as insect nets. (Aren't those items on every Mom's list?)
