They do.
Just check out the Bohart Museum of Entomology's newly published calendar.
"Mr. January" is a locust sitting quite comfortably in a chair--a swivel chair at that--and eagerly accessing a dating site. "You've got a match!" the screen informs him.
Yippee! You can almost hear him yelling "Yippee."
The caption reads: "Normally, locusts are introverted creatures; they do not socialize unless it is for reproduction."
The rest of the story: Lynn Kimsey, director of the Bohart Museum of Entomology and longtime professor of entomology at the University of California, Davis, collects unusual answers on the student tests she administers. You can imagine how many sentences comprise her collection: she joined the faculty back in 1989!
The "dating locust" is one of 12 from the Lynn Kimsey Prized Collection that made it into the Bohart's first-ever calendar. UC Davis entomology major Karissa Merritt, a talented artist and scientist known for her creativity and sense of humor, interpreted and illustrated all the sentences.
The calendar, a project of the non-profit Bohart Museum Society, sells for $12, plus tax, at the Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane. (More information is available on the website or by contacting bmuseum@ucdavis.edu or (530) 753-0493.) It's also available in the UC Davis Department of Entomology and Nematology administration office in 367 Briggs Hall.
Those who contribute $50 or more to the Bohart Museum Society will receive a calendar with their donation. All proceeds are earmarked for research, education and outreach projects.
Merritt says insects fascinate her. She's amazed at how "alien their biology and morphology are as compared to vertebrates." She's also drawn to their beauty and diversity.
Professor Kimsey, who holds a doctorate in entomology from UC Davis, directs the world-renowned Bohart Museum, home of eight million specimens, a year-around gift shop and a live "petting zoo" which includes Madagascar hissing cockroaches, walking sticks and tarantulas. She specializes in bees, wasps and insect diversity.
And collecting sentences--many apparently from sleep- or caffeine-deprived students.

Ever seen the male European wool carder bee (Anthidium manicatum) protecting its turf?
It's "no-holds barred" on our blue spike sage (Salvia uliginosa) and frankly, it's a delight to see and photograph.
The highly territorial male body-slams all floral visitors, including honey bees, bumble bees, carpenter bees and butterflies that are trying to seek a little nectar, too.
The wool carder bee (so named because the female scrapes or cards leaf fuzz for her nest) is an Old World bee belonging to the family Megachilidae (which also includes leafcutter and mason bees, among others). Accidentally introduced into the United States from Europe, this pollinator was first discovered in New York State in 1963, and then spread across the continent. Scientists found it in Davis, Calif. in 2007.
In size, wool carder bees are comparable to honey bees. They're readily distinguished, however, by their striking yellow markings on their black abdomens, and yellow faces. Males are considerably larger than females, and have a spine on either side of the last two abdominal segments and three spines on the last segment, according to Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis. Those spines have been mistaken for stingers, but only females have stingers.
One thing's for sure: their highly aggressive behavior tends to make honey bees forage faster! They don't want to get bonked! (Davis insect photographer Allan Jones aptly calls them "bonker bees.")
In our little pollinator garden in Vacaville, Calif., European wool carder bees seem to prefer blue flowers, especially our blue spike sage.
In fact, noted entomologist George Eickwort, writing in 1980 in the journal Psyche, observed that they seem to prefer "blue flowers with a relatively long throat."
We've seen the male carder bees protect patches of lamb's ear, foxgloves, catmint, oregano, cosmos, African blue basil, and Mexican sunflower (Tithonia).
However, they seem to go "bonkers" over bluebeard (Caryopteris x clandonensis) and blue spike sage (Salvia uliginosa).

The Anise Swallowtail, Papilio zelicaon, fluttered into our pollinator garden and headed straight for the Verbena.
Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, identified the gender: "it's a girl."
The Anise Swallowtail, our first sighting of the season, bypassed the butterfly bush, Buddleia davidii.
But she'll be back--hopefully to gather some more nectar and lay her eggs on our fennel.
The Verbena patch was a little too populated for her liking--honey bees and yellow-faced bumble bees, Bombus vosnesenskii, wanted their share of the nectar, too.
"The Anise Swallowtail is a complex set of ecological races, or 'ecotypes,' whose seasonality has been adjusted by natural selection to match that of their host plants," says Shapiro on his research website. He's studied butterfly populations in central California since 1972.
"In multivoltine populations the spring brood is typically small, pale, heavily marked with blue and with narrow dark borders on all wings. Summer individuals are larger, with richer yellow color, broader black borders and little or no blue in males. Univoltine populations tend to be intermediate between these extremes. The small larvae resemble bird droppings. Large larvae are pale green with black bands containing orange spots; in hot, dry sites there is more green and less black, while under cool, humid conditions the green may even disappear! The pupae may be brown or green."
Read more about the swallowtail, including its food sources, on Shapiro's web page.
Meanwhile, whether you see your first Anise Swallowtail of the season or the last of the season, you'll want to see more of this yellow-mellow butterfly!

Nice to see you!
That's how we greeted our very last bumble bee of 2016.
The yellow-faced bumble bee, Bombus vosnesenskii, apparently came out of hibernation and started nectaring on mallow Nov. 14 at the Natural Bridges State Park, Santa Cruz. We were at the park to see the overwintering monarch butterflies, but it was definitely delightful to see another insect species as well.
Ms. Bombus buzzed from one mallow to the other, keeping her distance from the two-legged park visitors. Once she nearly collided with an overwintering monarch heading for tropical milkweed blossoms.
B. vosnesenskii, native to the west coast of North America and found from British Columbia to Baja California, is an iconic pollinator and also an important pollinator for such crops as greenhouse tomatoes. It's among the bumble bees featured in the book, Bumble Bees of North America: An Identification Guide (Princeton University), the award-winning work of Paul H. Williams, Robbin W. Thorp, Leif L. Richardson and Sheila R. Colla.
When you click on the Princeton site, you'll hear the familiar buzz of bumble bees. It's just like encountering them in a wildflower meadow and listening to them take flight. It's a sound, unfortunately, that we're not hearing that much any more. The world's bumble bee population is declining, and some species are extinct or critically imperiled.
Speaking of bumble bees, did you see the paper, “Bumble Bees of Montana,” published this week by faculty and students in the Montana State University College of Agriculture in the Annals of the Entomological Society of America (AESA)? The scientists researched and compiled the state's first inventory of bumble bees known to live in Montana.
"The first time a bumble bee was recorded in Montana was in the journals of the Lewis and Clark expedition in 1805," wrote Jenny Lavey of the MSU News Service.
Four scientists co-authored the paper:
- Michael Ivie, associate professor of entomology in the MSU Department of Plant Sciences and Plant Pathology
- Kevin O'Neill, professor of entomology in the MSU Department of Land Resources and Environmental Sciences,
- Casey Delphia, MSU research scientist, and
- Amelia Dolan, former MSU entomology graduate student
"Because of Montana's size, landscape diversity and regional junction of eastern and western geographies, when it comes to bumble bees, Montana hosts a diverse, large and globally relevant community of species,” Ivie said in the news release. “Our research shows 28 different species of Bombus, with four more expected to make the list. That's the largest number of bumble bee species recorded for a state in the entire country."
Said Dolan: "It was amazing because we had people collecting specimens across the state, in varying elevations and diverse ecosystems – areas we alone wouldn't have had access to in the time that we had to complete the project. The number of species is representative of Montana's wild spaces and diverse landscapes that host these bees."
When was Bombus vosnesenskii first recorded in Montana? In 1923 (Frison).
If you want to hear more about bumble bees and other bees (some 1600 species of bees reside in California), be sure to attend a free two-hour presentation on "Bee Aware Bee Cause" at 1:30 p.m., Saturday, Jan. 7 by Robbin Thorp at the Rush Ranch Nature Center, 3521 Grizzly Island Road, Suisun. A worldwide expert on bees, Thorp is a distinguished emeritus professor of entomology at UC Davis who continues his research, writings and bee identification work.

Monarch butterflies are migrating now, but we're still finding a few caterpillars in our pollinator garden in Vacaville, Calif.
We recently plucked off five caterpillars from our milkweed plants (our game plan is protect them from California scrub jays and other birds, tachinid flies, wasps and the protozoan parasite, Ophryocystis elektroscirrha or OE, for short).
These are the last 'cats of the season.
Ours is a small-scale conservation project. Our goal is to reach 50 by the end of the season. We're on track to do our small part for the declining monarch population. Plant milkweed (the host plant of monarchs), plant nectar-rich flowers such as Mexican sunflower (Tithonia), butterfly bush (Buddleia) and Lantana, and Danaus plexippus will come.

Weiford works inside the French Administration Building, named for former president C. Clement French. When I joined the Daily Evergreen news staff--way back when!--I used to interview Dr. French.
Small world.
And it became even smaller when the WSU-tagged monarch (monarch@wsu.edu), part of WSU entomologist David James' research program, stopped by for a visit. It was reared by citizen scientist Steve Johnson of Ashland, and tagged and released on Sunday, Aug. 28. "So, assuming it didn't travel much on the day you saw it, it flew 285 miles in 7 days or about 40.7 miles per day," James said. "Pretty amazing."
Yes, pretty amazing, indeed.
Now, with any luck--well, lots of luck--Steve Johnson's progeny has made its way to an overwintering colony in Santa Cruz or Pacific Grove.
And with any more luck, we'll be adding five more to the overwintering site.
