A Big Butterfly-and-Bee Day at the Bohart

It was a big butterfly-and-bee day at the Bohart.

Despite other major attractions--including the gorgeous spring day and the March Madness basketball tournament--nearly 300 people visited the UC Davis Bohart Museum of Entomology last Saturday during its three-hour open house, themed "Eggs to Wings: Backyard Butterfly Gardening."

They conferred with Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis; Robbin Thorp, distinguished emeritus professor of entomology; Tabatha Yang, education and outreach coordinator; and a number of Bohart associates, including entomologist Jeff Smith, who curates the moth and butterfly display; naturalist Greg Kareofelas, a butterfly and dragonfly enthusiast; entomologists Jessica Gillung and Ziad Khouri, doctoral candidates; Nicole Tam, junior specialist; and Joel Hernandez and Alex Nguyen, recent entomology graduates.

 "Hungry, hungry caterpillars!" read one poster, illustrated with photos of the monarch, gulf fritillary and pipevine swallowtail caterpillars and their adult stages. "Having a garden full of flowers provides nectar, an important food source for adult butterflies, but what about their hungry, hungry caterpillars? It seems counterintuitive to grow plants that yu want insects to eat, but that is exactly what butterflies need when they are larvae."

The poster, the work of Tabatha Yang (with photos by yours truly), pointed out that monarch caterpillars eat only milkweed (genus Asclepias); gulf fritillary caterpillars eat only passionflower vine (genus Passiflora), and pipevine swallowtail caterpillars dine on the pipevine plant (family Aristolochiaceae).

Jeff Smith kept busy showing visitors the drawers of butterfly specimens, including blue morphos, monarchs and swallowtails. As he opened one drawer, he explained that "this drawer contains several species of South American rainforest butterflies, Preponas, in the genus Archaeoprepona." He described them as "extremely strong and fast fliers, but they love to settle on baits such as fermenting fruit on the ground. We (Bohart team) caught several in the ongoing Belize biodiversity work this past year."

Robbin Thorp showed live male Valley carpenter bees, Xylocopa varipuncta, green-eyed blond bees that are also known as "teddy bear" bees. "Boy bees can't sting," Thorp said, reassuring a few leary visitors. The female of the species is solid black. (Following the open house, Thorp returned the bees to the UC Davis Department of Entomology and Nematology's Häagen-Dazs Honey Bee Haven on Bee Biology Road.)

A family craft activity featured "wiggling caterpillars," made with with straw and paper. The youths also held Madagascar hissing cockroaches and walking sticks.

The Bohart gave away Patrón tequila bottles, donated by TJ's Tavern of Vacaville, for the "monarch starter set," which includes a zippered, meshed butterfly habitat (available for purchase at the Bohart gift shop and elsewhere) and a Patrón bottle.  The bottle is filled with water and milkweed cuttings and "just add monarch caterpillars." The bottles, embedded with a bee logo, are favored because they're sturdy with a broad base (so they won't tip over) and a narrow neck (so caterpillars can't fall in and drown).

The bottle is tucked inside a zipped, meshed butterfly habitat and placed indoors or in a screened patio to prevent tachinid flies and wasps from laying their eggs in the caterpillars or chrysalids. Once the monarchs pupate and eclose, they are released to start another generation. This is a small-scale conservation project.

The Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane,  is a world-renowned insect museum that houses a global collection of nearly eight million specimens. It also maintains a live “petting zoo,” featuring walking sticks, Madagascar hissing cockroaches and tarantulas. A gift shop, open year around, offers 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. The museum is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free. Special open houses take place throughout the academic year. The next open house takes place during the annual campuswide Picnic Day on April 22.
