The Bohart Museum of Entomology on the UC Davis campus is planning an open house on "How to Be an Entomologist" from 1 to 4 p.m., Saturday, Sept. 27. The insect museum is located in Room 1124 of the Academic Surge building, Crocker Lane, off LaRue Road.
The event is free and open to the public and is family friendly. This is the first of nine open houses during the 2014-15 academic year.
Plans call for a number of UC Davis entomologists to participate--to show and explain their work, said Bohart Museum director Lynn Kimsey, professor of entomology, UC Davis Department of Entomology and Nematology.
"We will have a pinning and butterfly and moth spreading ongoing workshop with Jeff Smith and tips on how to rear insects," said Tabatha Yang, the Bohart Museum's education and outreach coordinator. Smith, an entomologist in Sacramento, is a longtime donor and volunteer at the Bohart.
Representatives from the labs of molecular geneticist Joanna Chiu, assistant professor; bee scientist Brian Johnson, assistant professor; ant specialist Phil Ward, professor; insect demographer James R. Carey, distinguished professor; and integrated pest management specialist Frank Zalom, distinguished professor and current president of the 7000-member Entomological Society of America will share their research.
The Johnson lab will provide a bee observation hive, and Cindy Preto of the Zalom lab will be sharing her research on leafhoppers. The Carey lab will show student-produced videos, including how to make an insect collection, and one-minute entomology presentations (students showcasing an insect in one minute). The Ward lab will be involved in outside activities, demonstrating how to collect ants. Entomology students will be on hand to show visitors how to use collecting devices, including nets, pitfall traps and yellow pans.
Other entomologists may also participate. "There will be a lot going on inside the Bohart and outside the Bohart," Yang said. "It will be very hands-on."
The Bohart Museum, founded by noted entomologist Richard M. Bohart (1913-2007), houses a global collection of nearly eight million specimens and boasts the seventh largest insect collection in North America. It also houses the California Insect Survey, a storehouse of the insect biodiversity. The Bohart Museum's regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. The museum is closed to the public on Fridays and on major holidays. Admission is free.
The museum's gift shop (on location and online) includes T-shirts, sweatshirts, books, jewelry, insect-collecting equipment and insect-themed candy.
Special attractions include a “live” petting zoo, featuring Madagascar hissing cockroaches, walking sticks and tarantulas. Visitors are invited to hold the insects and photograph them. The newest residents of the petting zoo are Texas Gold-Banded millipedes, Orthoporus ornatus, which are native to many of the southwestern United States, including Texas.
“They're a great addition to the museum's petting zoo,” Kimsey said. “They are very gentle and great for demonstrations of how millipedes walk and how they differ from centipedes.”
Millipede enthusiast Evan White, who does design and communications for the Robert Mondavi Institute for Wine and Food Science, and is a frequent presenter at the Bohart's open houses, recently obtained the arthropods from a collector in Texas. “Texas Gold-Banded millipedes are naive to many of the Southwestern United States, not just Texas,” he said.
Contrary to popular belief, millipedes are not dangerous. “There is much public confusion about the difference between millipedes and centipedes--not because the two look similar, but because the terms are used interchangeably when not connected to a visual,” White said.
He described millipedes as non-venomous, and relatively slow moving, with cylindrical bodies, two pairs of legs per body segment, and herbivorous. “In fact, they are more like decomposers – they do well on rotting vegetation, wood, etc.--the scientific word for is ‘detritivore.' Most millipedes are toxic if consumed, some even secrete a type of cyanide when distressed. The point being: don't lick one.”
In contract, centipedes are venomous, fast-moving insects with large, formidable fangs, and one pair of legs per body segment. “They are highly carnivorous, although some will eat bananas. Go figure. And they are often high-strung and aggressive if provoked.”

If you are interested in growing pomegranates while maximizing water and nitrogen use efficiency, you may want to register for a meeting that will be held at Kearney on October 2, 2014.
Individuals interested in growing pomegranates with surface or subsurface drip irrigation are invited to attend a meeting at Kearney Agricultural Research & Extension Center (KARE) on October 2, 2014, to learn about improving pomegranate fertigation and nitrogen use efficiency. To attend, a reservation made with Diana Nix at 559-46-6500, extension 0, is required.
The field day will share the results of a fertigation study at KARE that uses high frequency drip and subsurface drip irrigation/fertigation systems. Check in is at 9:30 am, presentations start at 10:00 am, and the tour of the research plot begins at 11:00 am. The meeting will adjourn at noon.
The agenda includes:
- Introduction, objectives, orchard configuration and operation
- Evapotranspiration, crop coefficient and lysimeter management
- Yields, water use efficiency, and nitrogen use efficiency
- Soil matric potential measurements and hydraulic gradient calculations in the subsurface drip irrigated lysimeter
- Tissue responses to high frequency injected nitrogen at three levels of nitrogen
- Canopy cover and leaf chlorophyll measurements
- Conclusions and questions
For additional information, please contact Kevin R. Day, UC Cooperative Extension advisor in Tulare County, specializing in fresh-shipping deciduous tree fruits, cultural practices and production, fruit growth and development, pruning and training systems, at 559-684-3311, or Claude J. Phene, President of SDI Plus, at 559-298-0201.

How can you hate a caterpillar and love a butterfly?
Some gardeners so love their passionflower vine (Passiflora) that they squirm at the thought of a caterpillar munching it down to nothing.
But that's what caterpillars do. The Gulf Fritillary butterfly (Agraulis vanillae) lays its eggs on its host plant, the passionflower vine, the eggs develop into larvae or caterpillars, and the caterpillars into Gulf Frits.
Our passionflower vine--which we planted specifically for the Gulf Frits--is now a skeleton. The caterpillars ate all the leaves, the flowers and the stems. What was once a flourishing green plant looks like a criss-cross of brown sticks.
Comedian George Carlin supposedly said "The caterpillar does all the work but the butterfly gets all the publicity."
And architect-author-designer-inventor Richard Buckminster Fuller observed: "There is nothing in a caterpillar that tells you it's going to be a butterfly."
And someone named John Grey offered this poetic comment:
"And what's a butterfly? At best,
He's but a caterpillar, at rest."
So, it is. Take a look at the Gulf Frit caterpillar and then check out the Gulf Frit butterfly.
Yes, a hungry caterpillar turned into a magnificent butterfly.

We all take shortcuts.
We look for the shortest line at the supermarket, we use keyboard shortcuts, and we text ”how r u?”
So, why shouldn't honey bees use shortcuts? They do.
If you've ever watched a carpenter bee drill a hole in the corolla of a tubed flower to get at the nectar—this is "nectar robbing" or bypassing pollination—you may have seen a honey bee come along and sip nectar from the hole. Why work hard to get at the nectar when it's right there for the taking?
This is the insect version of a convenience market!
Take the foxgloves (family Plantaginaceae, genus Digitalis). Sometimes you'll see a honey bee trailing or shadowing a carpenter bee that moves from corolla to corolla.
Short cut to the nectar!
