Bumble bees and spiders don't mix, you say?

Well, they will at the Bohart Museum of Entomology's open house from 1 to 4 p.m., Saturday, July 26. The family-centered event, free and open to the public, takes place in Room 1124 of the Academic Surge building on Crocker Lane, UC Davis campus.

Actually the theme is about spiders: "Arachnids: Awesome or Awful?" There you'll see black widow spiders, jumping spiders, cellar spiders and the like. But you don't have to "like" them as you do posts on Facebook!

You can also learn about bumble bees. Native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis, will be one of the tour guides.  Thorp co-authored the newly published Bumble Bees of North America: An Identification Guide, which is available in the Bohart gift shop. He can autograph your book and answer questions about how to attract bees to your garden.

Thorp was recently interviewed by Tom Oder of the Mother Nature Network on how to garden for bumble bees. So was Steve Buchmann, an adjunct professor in entomology and ecology at the University of Arizona.

Thorp told Mother Nature Network that some bumble bees are in very serious decline, and others are doing quite well.

So, how do you attract them to your garden? Buchmann was quoted as saying: “Gardening for bumblebees is similar to gardening for other bees and pollinators."  To entice bumblebees to visit your garden, “plant mints, Salvia, Monarda, plants in the sunflower family and clovers."

Read Oder's article for more information.

And keep your eyes open for the soon-to-be-published California Bees and Blooms: A Guide for Gardeners and Naturalists, co-authored by entomologist Gordon Frankie of UC Berkeley, Thorp, and two others with UC Berkeley connections: photographer/entomologist Rollin Coville and floral curator Barbara Ertter.

As for Saturday, July 26 there won't be a vote on whether you like bumble bees or spiders better, nor will you be asked to sing "Itsy Bitsy Spider" or "Baby Bumble Bee." It promises, though, to be fun and educational. Plus, you can enjoy the live  "petting zoo," featuring 24-year-old Rosie the tarantula, assorted walking sticks, and the colorful Madagascar hissing cockroaches. Yes, they hiss.

The gift shop is also popular. You can browse through the books, jewelry, t-shirts, sweatshirts, insect-themed candy, butterfly houses, and insect-collecting kits.

The Bohart Museum, directed by Lynn Kimsey, professor of entomology at UC Davis, houses 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 insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum.

The museum's regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. It's closed to the public on Fridays and on major holidays. Admission is free.
