Lynn Kimsey, director of the Bohart Museum of Entomology, located at 1124 Academic Surge on California Drive, UC Davis campus, knows that a Halloween party isn't a party without the appropriate butterfly, ladybug and honey bee costumes.
After all, the museum houses a global collection of more than seven million specimens (and some live insects, including Madagascar hissing cockroaches, walking sticks and tarantulas).
The Bohart Museum Society party, held tonight (Thursday), drew scores of costumed folks who enjoyed the camaraderie, the refreshments, the gift shop, the specimens and the "live petting zoo." Toward the end, they took time to bash a mosquito pinata, made by Brittany Nelms, a PhD student within the Entomology Graduate Group with a designated emphasis in Vectorborne Diseases. William Reisen of the Center for Vectorborne Diseases, serves as her major professor.
Mosquitoes are meant to be bashed.
UC Davis entomology graduate student Emily Bzdyk arrived as a butterfly, with her face intricately painted. Entomology graduate student Danielle Wishon, who studies with forensic entomologist Bob Kimsey and won the 2011 UC Davis Undergraduate Award in Entomology, selected a maggot theme.

When it was all over, Honey Lovers candy donated by Gimbal's Fine Candies of San Francisco, spilled out of the split mosquito pinata as the eager crowd dashed for the goodies.
On Sunday, Oct. 30, the Bohart Museum will host a free pre-Halloween open house for the public. It will take place from 1 to 4 p.m. Prizes will be awarded to the best insect costumes (youth and adult divisions) and the best insect tattoo.
And, oh, yes, there will be another blood-sucking mosquito to bash in the form of a pinata.

Staff at the UC Davis School of Veterinary Medicine's Center for Equine Health encountered "a strange little bug" that they'd never seen before outside their office Friday on Old Davis Road.
Barbara Meierhenry, senior editor at the Center for Equine Health, described it as "a strange little bug...It was about an inch long, with two rounded body sections covered with 'blond' fuzz, and six legs. He was actually very cute. We have never seen a bug like this before."
She emailed us two cell-phone images taken by Equine Control Officer Laurie Christison.
Enter UC Davis bug experts. Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis, quickly identified it as a "female velvet ant (family Mutillidae)."
Native pollinator specialist Robbin Thorp, emeritus professor of entomology, added: "The photo is of a female velvet ant, genus Dasymutilla, family Mutillidae. The females are wingless and parasitize ground-nesting bees. The males are winged. These ants are not commonly seen. They're usually associated with sandy soil, and are mostly active on cloudy days or at night. Males squeak when handled, females have powerful stings, so it's not a good idea to try to handle them."
Meierhenry speculates the velvet ant "may have come here on a hay truck as we had a delivery of hay on Friday. In the years we have both worked here, we have never seen such a creature."
As a side note, renowned insect photographer and ant specialist Alex Wild, based in Illinois, posted a Mutillidae family member on his popular Monday night insect quiz last February. He titled it "What's That Fuzz?" The responders got the genus right: Dasymutilla, but differed somewhat on the species.
For another amazing photo of Dasymutilla, check out Alex Wild's Dasymutilla gloriosa, aka Thistledown Velvet Ant. Talk about a good hair day!
By the way, Wild, who received his doctorate in entomology at UC Davis in 2005, studying with major professor Phil Ward, will return to UC Davis this week to speak on insect photography. His talk is Wednesday, Oct. 26 from 12:10 to 1 p.m. in 122 Briggs Hall. Professor James R. Carey plans to webcast the seminar and post it on UCTV.
It's a good week for bugs!

It's good to see so many people looking for the critically imperiled Franklin's bumble bee, which the U.S. Fish and Wildlife Service may soon list as “endangered” and provide protective status.
Native pollinator specialist Robbin Thorp, emeritus professor entomology at UC Davis, has been tracking the elusive bumble bee since 1998. Its only known location is in a narrow range in northern California (Siskiyou and Trinity counties) and southern Oregon (Jackson, Douglas and Josephine counties).
He's seen it only once since 2006.
But now Robbin Thorp has a "posse" on the lookout for the elusive bumble bee.
After The News-Review, Douglas County, Ore., published a news story and photo of the bumble bee on Sept. 13, nearly two dozen people "called or wrote...to say they thought they had spotted Franklin's bee," wrote reporter John Sowell in the Oct. 12 edition.
Alas, it was not to "bee." Thorp identified the residents' photos as mostly the yellow-faced bumble bee, Bombus vosnesenskii.
"There are a lot of lookalikes out there," Thorp told Sowell.
Franklin's bumble bee, Bombus franklini (Frison), is mostly black with distinctive yellow markings on the front of its thorax and top of its head. It has a solid black abdomen with just a touch of white at the tip, and an inverted U-shaped design between its wing bases,In contrast, the yellow-faced bumble bee has a yellow face. its thorax and abdomen are mostly black but it has yellow band near the tip of the abdomen.
So, bottom line, if you see a bumble bee with yellow on its face and a yellow band at the tip of the abdomen, it's not our buddy, Franklin's bumble bee.
To check a puzzling identity, email your photo to Robbin Thorp at email@example.com
As Thorp told reporter Sowell: "The more eyes that are looking for it, the better it's going to be."

Native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis, is on a mission.
He and fellow members of the Xerces Society for Invertebrate Conservation are trying to save Franklin's bumble bee from extinction.
So the news that came out today about this critically imperiled bumble bee was both good and bad.
It's good that the U.S. Fish and Wildlife Service (USFWS) today announced that the petition submitted by Thorp and the Xerces Society in June 2010 to list Franklin’s bumble bee under the National Endangered Species Act has moved to the next step in the process, the 12-month review period. This may lead to an “endangered species” listing and provide protective status.
That's good. But it's bad in that Franklin's bumble bee hasn't been seen since 2006.
It's possible that it may already be extinct but Thorp holds out hope. He's been monitoring the declining population since 1998.
Franklin’s bumble bee, Bombus franklini (Frison), occupies only a narrow range of southern Oregon and northern California. Its range, a 13,300-square-mile area confined to Siskiyou and Trinity counties in California; and Jackson, Douglas and Josephine counties in Oregon, is thought to be the smallest of any other bumble bee in North America and the world.
Thorp, who maintains an office at the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis, sighted 94 of the species in 1998, but only 20 in 1999. The numbers soon began declining drastically (except for 2002):
2000: Nine sightings
2007 through 2011: None.
This year Thorp surveyed the bumble bee's historical sites on five separate trips encompassing several days each: two in June and one each in July, August and September.
Zip. Zilch. Nada.
Franklin's bumble bee, mostly black, has distinctive yellow markings on the front of its thorax and top of its head. It has a solid black abdomen "with just a touch of white at the tip, and an inverted U-shaped design between its wing bases," Thorp said.
Take a close look at his photo of Franklin's bumble bee on a California poppy, the state flower. Let's hope it's not one of the last photos of this unique bumble bee.
Robbin Thorp thinks he'll find it again.
“My experience with the Western bumble bee (B. occidentalis) indicates that populations can remain ‘under the radar’ for long periods of time when their numbers are low,” he said.

A good time to photograph the European wool carder bee is in the early morning when it's warming its muscles to prepare for flight.
It lies perfectly still.
That's what it did in our yard last weekend. It warmed itself on the sunny side of a leaf.
Not unlike the sunny side of a street...
The European wool carder bee (Anthidium manicatum), so named because the female "cards" or collects plant material to line her nest, is a relative newcomer to the United States. UC Davis research entomologist Tom Zavortink of the Bohart Museum of Entomology says it was accidentally introduced into New York State before 1963.
Writing in a 2008 edition of the Pan-Pacific Entomologist, Zavortink and fellow entomologist Sandra Shanks now of Port Townsend, Wash., pointed out that several papers “have documented its spread from neighboring areas in the northeastern United States and southern Canada” and that the species has since crossed the country. It was confirmed in Colorado in 2005, Missouri in 2006, and Maine, Michigan, Maryland and California (Sunnyvale) in 2007, the entomologists wrote.
The bee is mostly black and yellow. At first glance, its stark markings remind you of a yellowjacket. The females, about the size of a worker honey bee, range in body length from 11 to 13 millimeters, while the males are 14 to 17 mm.
The males can be aggressive in defending their territory, sometimes body-slamming honey bees and other insects to the ground.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis, says that this kind of contact has a purpose. The male wool carder bee is "merely defending its territory from honey bees and other flying insects to keep the area free of potential competitors that might interfere with its mating opportunities," he says.
One thing's for sure: they do move fast!
Except in the early morning when they're warming their flight muscles...
