That's what happened Sunday. A dragonfly--identified by naturalist Greg Kareofelas, volunteer at the Bohart Museum of Entomology, UC Davis as a female Sympetrum madidum--zigzagged into our yard and began catching flies, sweat bees and other soft-bodied insects near our fish pond.
It favored a series of bamboo stakes, installed there just for the dragonflies. It moved from one to another as if trying to decide which one it liked the best.
It appeared to like them all! It stayed for four hours.
This dragonfly, also called a red-veined meadowhawk, belongs to the family Libellulidae, the same family as our favorite red flameskimmers (Libellula saturata).
Most of the dragonflies we've encountered are quite skittish—you can't go within 25 feet before they dart off. Not this one. It allowed us to get within an inch of it. Guess it figured we were no threat. Curious, yes. Predator, no.
Nearby, however, scrub jays nesting in the cherry laurels popped out occasionally to find food for their chirping offspring. Fortunately, Ms. Sympetrum madidum wasn't on the menu.

Hint: It's the state insect.
"What, we have a state insect?" you ask.
Yes, and it's the California dogface butterfly (Zerene eurydice).
On the monorail, it's an artistic blue and white and it seems to flutter along for the ride. (See what the Monorail Society wrote about it in 1995.) In real life, the male of the species is yellow and black, and the female, predominantly yellow.
Fran Keller, doctoral candidate in entomology at the University of California, Davis, and her colleague, naturalist Greg Kareofelas of Davis, a volunteer at the Bohart Museum of Entomology identified the insect on the monorail right away. Several years ago they teamed to create a California dogface butterfly poster, which graces many a classroom, office, and den. The poster is for sale in the Bohart Museum's gift shop on Crocker Lane, UC Davis, or online.
Keller went on to write a children's book, "The Story of the Dogface Butterfly," with watercolor-and-ink illustrations by Laine Bauer, a 2012 graduate of UC Davis. Kareofelas contributed photographs.
Net proceeds from the sale of the 35-page book, also available at the Bohart Museum or online, benefit the insect museum's education, outreach and research programs.
The book tells the untold story of the California dogface butterfly, and how schoolchildren became involved in convincing the State Legislature to select the colorful butterfly as the state insect.
Bauer’s illustrations depict the life cycle of this butterfly. As part of their research, Keller, Karofelas and Bauer visited a Placer County habitat of the butterfly last year.
As for the book, “There are also ecology, life cycle, taxonomy and conservation issues presented that are relevant to grades K-6 that can be used in classroom curriculum,” Keller said. In addition, the book includes information on the butterfly’s host plant, false indigo (Amorpha californica).
So, score one for the California State Fair. And score two for the Bohart Museum.

What a beauty.
But not nearly as striking as her male counterpart.
The flame skimmer dragonfly (Libellula saturata) owned a perch on a bamboo stake last Tuesday in residential Davis.
Davis resident Gary Zamzow, a dynamite insect photographer (especially bumble bees), pointed his Pentax camera at the insect, just inches away.
The dragonfly did not move.
“The female flame skimmers are not as intensely orange as the males are and they also have the expansions on the 7th abdominal tergite that you can see in your picture (below),” said senior museum entomologist Steve Heydon of the Bohart Museum of Entomology (http://bohart.ucdavis.edu/), University of California, Davis.
If you like dragonflies, you may want to purchase a dragonfly poster at the museum, located in Room 1124 of the Academic Surge building on Crocker Lane, or online at its gift shop. It features 18 species of dragonfies, ranging from the common whitetail and green darner to the Western river cruiser and the bison snaketail. And, of course the flame skimmer.
Entomology doctoral candidate Fran Keller designed the poster with images provided and donated to the museum by naturalist Greg Kareofelas of Davis.

If you or someone in a household near you can draw a bug, then you need to head over to the Bohart Museum of Entomology on the UC Davis campus on Saturday afternoon, Dec. 15.
The Bohart Museum is hosting an open house from 1 to 4 p.m. in Room 1124 Academic Surge on Crocker Lane. It's free and open to the public.
The theme: "Insects in Art."
The person (all ages invited) who submits the most creative bug drawing between 1 and 3:30 p.m. will win a t-shirt at around 4 p.m.
Here's what you do: draw a bug that will fit into a button about 2-1/4 wide. The Bohart Museum folks will insert it into their button-maker machine. If your bug art is selected as the most creative, you take the button home--and your prize, an insect-related t-shirt.
The open house will feature the illustrations of Lynn Kimsey, director of the Bohart and professor of entomology at UC Davis; the late Mary Foley Benson of Davis; and Ivana Li, an undergraduate entomology student and president of the UC Davis Entomology Club.
Visitors also will be able to see the original plates for the children’s book, “The Story of the Dogface Butterfly,” written by Fran Keller, doctoral candidate in entomology, and Laine Bauer, who received her degree in art in June from UC Davis. Greg Kareofelas of Davis, a Bohart volunteer, contributed photos.
Expanding on the open house theme, Heydon said that “Insects and Art” began as early as the caveman days. Cave drawings found in Spain depict honey gatherers from more than 10,000 years ago.
“Insects in art are found in scientific illustrations and are represented on fabric, paintings, toys, jewelry and other media,” Heydon said.
The Bohart Museum houses a global collection of nearly eight million insect specimens and is the seventh largest insect collection in North America. It is also the home of the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum in 1946.
In addition to the insect specimens, the Bohart houses a “live petting zoo” of Madagascar hissing cockroaches, walking sticks and tarantulas; and a gift shop filled with t-shirts, sweatshirts, jewelry, posters, insect nets, and insect-themed candy.
Bohart officials schedule weekend open houses throughout the academic year so that families and others who cannot attend on the 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 remaining weekend open houses:
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"
Saturday, April 20: 10 a.m. to 3 p.m.
Theme: UC Davis Picnic Day
Saturday, May 11, 1 to 4 p.m.
Theme: "Moth-er's Day"
Sunday, June 9, 1 to 4 p.m.
Theme: "How to Find Insects"

It's a joy to watch these firecracker-red dragonflies (Libellula saturata) make their presence known. They dart over our fish pond, snatch an insect, and then perch on a tomato-plant stake to eat it.
Last year another generation did the same thing. They darted over our fish pond, snatched an insect, and then staked their claim in the vegetable garden. Over a tomato plant.
Most of the time the flame skimmers seem unaware of my presence. Guess they consider me neither prey nor predator.
If you love dragonflies, several years ago the Bohart Museum of Entomology, University of California, Davis, created an educational poster, "Dragonflies of California," the work of doctoral candidate Fran Keller and naturalist/photographer Greg Kareofelas of Davis. It focuses on 18 dragonflies commonly found in the Golden State. The largest insect depicted in the poster is the Giant Darner (Anax walshinghami), but the most colorful just has to be...drum roll...the flame skimmer. But I'm biased.
Keller came up with these facts about dragonflies:
Ten fast facts about dragonflies, as provided by the Bohart Museum:
- Dragonflies date back before the dinosaur age.
- The largest known prehistoric species of dragonfly, living 300 million years ago, was the Meganeura monyi. Its wingspan measured more than two feet long.
- The largest species today is a South American dragonfly with a wingspan of 7.5 inches. The smallest modern species is an east Asian dragonfly, the libellulid dragonfly, Nannophya pygmaea, with a wingspan of about 3/4 of an inch.
- California is home to approximately 108 species. More than 5000 species are found worldwide.
- Dragonflies help control pests such as mosquitoes, midges and flies, but will also dine on honey bees and butterflies.
- The adults feed by hawking their prey. They dart off a perch to catch prey and often return to the perch to eat.
- Most dragonflies live around lakes, ponds, streams, and marshes; their larvae, known as “nymphs,” are aquatic. Some dragonfly larvae live in bromeliad flowers.
- Dragonflies usually do not bite or sting humans, but if grasped by the abdomen, they may bite to escape.
- The dragonfly is thought to have better eyesight than any other insect. Its compound eyes take up much of the insect’s head. Each compound eye has up to 30,000 facets or sensor modules, arranged to provide nearly a 360-degree field of vision. That's why it's difficult to sneak up on them.
- Dragonflies are a common motif in Native American art, displayed on Zuni pottery, Hopi rock art and on Pueblo necklaces. In Japan, they are considered symbols of courage, strength and happiness.
The Bohart Museum, home of more than seven million insects, is open year around, but is closed to the public on Friday. It's directed by Lynn Kimsey, professor of entomology att UC Davis.
But if you want to see dragonflies in The Great Outdoors, look for them near a body of water, whether it be a river, creek or...a fish pond in the back yard...
