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.

A perfect perch.
A young male variegated meadowhawk dragonfly, Sympetrum corruptum, found a perfect perch--a seed ball of Mexican sunflower (Tithonia) in our pollinator garden in Vacaville, Calif.
It towered over the garden and so did he.
Naturalist Greg Kareofelas, Bohart Museum of Entomology associate, University of California, Davis, has been seeing and photographing some of these migrating dragonflies in his yard in Davis as well.
"Evidently, there was a big migration of lots of these dragonflies south of San Francisco," Kareofelas noted in his Facebook post.
And apparently thousands have been spotted at Half Moon Bay. Dragonfly alert!
Variegated meadowhawks live near ponds, lakes, and swamps. They are largely tan or gray with a pale face that is tan in young males and females but becomes red in mature males, according to Odonatacentral.org. They're found throughout the United States and southern Canada; also Mexico south to Belize and Honduras. "This species may be seen on the ground more than other meadowhawks. It will also readily perch on the tips of grass stems and tree branches. It can be numerous flying over roads, lawns, meadows, marshes and ponds...It is largely tan or gray with a pale face that is tan in young males and females but becomes red in mature males."
The Bohart Museum, located in Room 1124 of the Academic Surge building on Crocker Lane, offers a beautiful dragonfly poster, "Dragonflies of California," in its gift shop. It's the work of entomologist Fran Keller (she received her doctorate in entomology from UC Davis and is now an assistant professor at Folsom Lake College) and Kareofelas, whose expertise includes butterflies and dragonflies.
Who doesn't love the red flameskimmer dragonfly, Libellula saturata?
If the Fourth of July had its own insect, it would be the firecracker red flameskimmer. It's so showy and eye-popping red that it almost looks patriotic. Or at least it should be flying over an Independence Day parade while a band plays "Yankee Doodle Dandy."
On a breezy day in the late spring, we can usually count on a flameskimmer or two entering our yard. Of course it helps if you have a pond and a pollinator garden and some bamboo stakes. They hover over our pond, turn the pollinator garden into their dining room, and perch on the stakes to eat their prey.
We managed to capture a few images of this one last weekend as it helicoptered from bamboo stake to bamboo stake. It "posed" against a shade-cloth fence, a pink background of Jupiter's beard, and with a little aperture changing, against a black background.
It stayed for a couple of hours.
More than enough to strike up a band to play "Yankee Doodle Dandy."
The flameskimmers are back!
We've been waiting for the new generation of flameskimmers, aka firecracker skimmers (Libellula saturata), to visit our yard after the long winter.
On Sunday, a male flameskimmer did.
It perched on a bamboo stake, soaked up some rays, took flight, and then returned to its perch. It glittered in the morning sun, a ruby helicopter of an insect. Finally, it clumsily took off, zigging and zagging over the cherry laurel hedge.
Meanwhile, a Western scrub jay nesting in the cherry laurels tracked its movements.
Says Wikipedia: "Due to its choice habitat of warm ponds, streams, or hot springs, flame skimmers are found mainly in the southwestern part of the United States. They also make their homes in public gardens or backyards."
"An immature flame skimmer (nymph) feeds mainly on aquatic insects. Its diet consists of mosquito larvae, aquatic fly larvae, mayfly larvae, freshwater shrimp, small fish, and tadpoles. The nymphs, which live in the mud at the bottom of warm streams or ponds, catch their prey by waiting patiently for it to pass by. Adult skimmers usually feed on moths, flies, ants, or any other soft-bodied insect while waiting perched on a small rock or twig or while flying through the air."
It's our fish pond that draws dragonflies to our yard. To accommodate them, we've posted a dozen bamboo stakes at different heights, from four feet to six feet. Finches and hummingbirds perch on them, too.
To be honest, however, the bamboo stakes are mainly for the dragonflies. (But don't tell that to the finches and hummers.)
It's a bird, it's a plane...
It's not Superman. It's a flame skimmer dragonfly (Libellula saturata).
We spotted this dragonfly in our yard recently and crouched down for a low angle, framing it against the sky.
This is one insect that everyone notices and admires.
Except maybe its prey...
