A female and male Gulf Frit find one another.
Near them, Gulf Frit caterpillars hungrily munch the leaves. Soon they will form a chrysalis. From egg to larvae to chrysalis to adult.
If you'd like to learn to rear butterflies, silkworm moths, praying mantids or tarantulas, attend the UC Davis Bohart Museum of Entomology open house on “Arthropod Husbandry: Raising Insects for Research and Fun” from 1 to 4 p.m., Saturday, Nov. 16 in Room 1124 of the Academic Surge Building on Crocker Lane. It's free and family friendly.
UC Davis student Andrew Goffinet, a former UC Davis Bio Boot Camper, will be on hand to talk about rearing butterflies and moths. UC Davis entomology alumnus Lohit Garikipati will discuss praying mantids. Another entomology alumnus Nicole Tam, will talk about rearing insects in the Geoffrey Attardo lab as part of research projects. Doctoral student and Bohart associate Zaid Khouri's topic is how to rear tarantulas and millipedes for fun.
"We also will be discussing Madagascar hissing cockroaches (hissers) as good options for 'starter pets' for kids, and some of the problems with stick insects (walking sticks)," said Tabatha Yang, education and outreach coordinator. Visitors are invited to hold the hissers and stick insects and photograph them.
At 3 p.m., silkworm moth expert İsmail Şeker, a Turkish medical doctor who wrote a book about silkworm moths and the cottage silk industry in his home town, will show his newly produced video about the silkworm moth life cycle. Seker, also a talented videographer and a photographer, will answer questions following his 13-minute video presentation.
"This will be a fun open house for anyone considering a pet with an exoskeleton," Yang said."It will be good for educators to learn about classroom 'pets,' including those who do work with silk moths for life cycle lesson plans."
"Also, to kick off the holiday season we will have the unique wire jewelry by former entomology major Ann Kao, so people should be prepared to shop for some unique insect-inspired jewelry." A family craft activity is also planned.
This is the last open house of the year. The next open house will be on Jan. 18 when UC Davis graduate students from many different fields "will be talking/displaying about their cutting edge research with insects," Yang said.
The Bohart Museum houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum. It maintains a live "petting zoo," featuring Madagascar hissing cockroaches, walking sticks or stick insects and tarantulas. The museum's gift shop, open year around, is stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
Director of the museum is Lynn Kimsey, professor of entomology at UC Davis. The staff includes Steve Heydon, senior museum scientist; Tabatha Yang, education and outreach coordinator; and Jeff Smith, who curates the Lepidoptera (butterflies and moths) section.

It's Veterans' Day, and after paying tribute to the military veterans (my ancestors have fought in all of our nation's wars, dating back to the American Revolution--and my other half is a U.S. Air Force veteran), I slip out the back door to our pollinator garden to see where the insect action is.
Honey bees and a sole carpenter bee are buzzing on the African blue basil; Gulf Fritillaries are nectaring on the Mexican sunflower (Tithonia); and a cabbage white butterfly is sipping nectar from the Lantana.
But the passionflower vine (Passiflora) steals the show. A Gulf Fritillary has just eclosed from a chrysalis that resembles a thick wad of gum chewed up and spit out and left to mummify; several male Gulf Frits are fluttering around in search of females; and the offspring of previous reunions are crawling on the stems and munching what's left of the leaves.
Overhead, the California scrub jays glance down, as if trying to decide on their luncheon menu: a fat juicy caterpillar or the bird seed scattered in the feeder.
Their choice is clear. They forsake the fat juicy caterpillars for the bird seed. Tomorrow morning, however, there will be several caterpillars missing in action.
Where are you, Gulf Fritillaries?
The Gulf Fritillary (Agraulis vanillae) population seems to be diminishing this year around Solano and Yolo counties.
A few here, a few there, but not in the large numbers of last year.
Last summer the Gulf Frits overwhelmed our passionflower vine (Passiflora), their host plant, and skeletonized it.
Which is what we want them to do. We plant Passiflora for them, not for the fruit or the blossoms. On a good year, they eat it all--blossoms, fruit, leaves and stems--and look for more.
The history of the butterfly in California is as striking as its silver-spangled, reddish-orange coloring.
“It first appeared in California in the vicinity of San Diego in the 1870s,” says noted butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis. “It spread through Southern California in urban settings and was first recorded in the Bay Area about 1908. It became a persistent breeding resident in the East and South Bay in the 1950s and has been there since.”
Shapiro, who has monitored butterflies in central California since 1972 and maintains a research website at http://butterfly.ucdavis.edu, says the Gulf Frit “apparently bred in the Sacramento area and possibly in Davis in the 1960s, becoming extinct in the early 1970s, then recolonizing again throughout the area since 2000.”
It's making a comeback, but this year it doesn't seem to be "coming back" so much.
Want to attract the Gulf Frit? Plant its host plant and some of its favorite nectar plants. In our pollinator garden in Vacaville, their favorite nectar sources include the butterfly bush (Buddleia), Mexican sunflower (Tithonia) and lantana (genus Lantana.)
Plant them and they will come--if they're around!
Entomologists at the University of California, Davis, will share their love of insects with fairgoers at the 144th annual Dixon May Fair, which opened today (Thursday, May 9) and continues through Sunday, May 12.
Have a question about insects?
Entomologist Jeff Smith, who curates the Lepitopdera (butterfly and moth) section at the Bohart Museum of Entomology, UC Davis, and Alex Dedmon, a forensic entomologist and doctoral student at UC Davis, will be showing bee, butterfly, dragonfly and other specimens, and live insects from the "petting zoo," including walking sticks and Madagascar hissing cockroaches. Fairgoers are encouraged to hold them, photograph them and ask questions.
Smith and Dedmon will be at the fair on Saturday, May 11 from 11 a.m. to 3 p.m. in the Floriculture Building. Smith was honored in 2015 as a "Friend of the College," a coveted award presented by the College of Agricultural and Environmental Sciences. He saved the museum some $160,000 over a 27-year period through his volunteer service (See news story.)
Dedmon studies with forensic entomologist Robert Kimsey, an adjunct professor in the UC Davis Department of Entomology and Neamtology.
The Bohart Museum, directed by Lynn Kimsey, professor of entomology, is the home of nearly eight million insect specimens, plus a year-around gift shop and a petting zoo. The gift shop is stocked with books, jewelry, t-shirts, insect-collecting equipment, insect-themed candy, and stuffed animals.
The Bohart Museum, founded in 1946 by UC Davis entomologist Richard “Doc” Bohart (1913-2007), is open to the general public Mondays through Thursdays, from 9 a.m. to noon and from 1 to 5 p.m., plus occasional, weekend open houses. Admission is free. The next weekend event will be "Moth Night" on Saturday, Aug. 3 from 8 p.m. to 11 p.m. Further information is available on the Bohart Museum website or contact (530) 753-0493 or firstname.lastname@example.org.
You can see them at the Bohart Museum of Entomology during the campuswide UC Davis Picnic Day, set Saturday, April 13. The theme is "Will Travel for Bugs: The Bohart Museum of Entomology's Collections From Around the World."
The Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane, will be open from 11 a.m. to 2 p.m., a change from last year's hours. The shorter hours will allow the Bohart Museum folks to help with the UC Davis Department of Entomology and Nematology's displays at Briggs Hall and the “Black Widow-on-Parade” entry in the UC Davis Picnic Day Parade.
"At the Bohart, we are focusing on the various countries from around the world and some of their insect fauna," said Tabatha Yang, education and outreach coordinator. The 12 countries that the Bohart is highlighting are:
- Democratic Republic of Congo
- Papua New Guinea
- Republic of South Africa
- United States
“So for anyone who is from there, has lived there, has visited there, or who wants to visit there, please come and take a peak at some unique insects from around the world,” Yang said. “Some people enjoy traveling to explore cuisine and culture, but traveling for the flora and fauna of the world is equally wonderful. Insects are an important part of nature, so be curious, not afraid.”
There's also something special about this year's display at the Bohart. Its exhibit, "Will Travel for Bugs: The Bohart Museum of Entomology's Collections From Around the World," has been nominated for the Planet Earth Award. "Visitors will have the opportunity to vote for their favorite exhibits in five award categories," according to Madhuri Narayan, UC Davis Picnic Day exhibits director. A QR code, linked to the voting survey, will be displayed at the museum. Or folks can vote here from 8 a.m. to 10 p.m. April 13. The prize for earning the most votes? "An awesome certificate and bragging rights," Narayan said.
Briggs Hall. At Briggs Hall, home of the UC Davis Department of Entomology and Nematology, the honey tasting booth has also been nominated for a special award. The Honey tasting is being organized by Extension apiculturistElina Lastro Niño. Briggs Hall will also offer maggot art, cockroach races, a bee observation hive and displays featuring aquatic insects, forensic entomology, and ants, among others, according to co-chairs forensic entomologist Robert Kimsey and doctoral student Brendon Boudinot. The Bug Doctor, the UC Statewide Integrated Pest Management Program, the Sacramento-Yolo Mosquito and Vector Control District, and the Davis Fly Fishers will staff booths. Also planned: insect face painting, t-shirt sales and a bake sale. Both the UC Davis Entomology Graduate Student Association, headed by president Boudinot, and the UC Davis Entomology Club, advised by Kimsey, will participate in the day's events.
Campuswide Picnic Day. The 105th annual UC Davis Picnic Day is free (free parking, free admission). It serves as the university's annual open house for prospective and current students, families, alumni, staff, faculty, and the greater Davis and regional communities. Picnic Day begins with the parade opening ceremony at 9:30 a.m., and the parade begins at 10 a.m. Most events will run from 10 a.m. to 4 or 4 p.m. (See website.)
