Silkworm moth expert İsmail Şeker, a Turkish medical doctor and author of a book showcasing his hobby, displayed the eggs, larvae, pupae, adults, as well as silk fabric, and fielded questions from the audience.
Seker showed his newly produced 13-minute video detailing the history of the silkworm moth and its life cycle. The crowd marveled at his macro photography and exquisite videography. Assisting him at the presentation were his grandson, Emre, 7, and granddaughter, Ruya, 4. Their father, Erkin Seker, is an associate professor in the UC Davis Department of Electrical and Computer Engineering.
The silkmoth, Bombyx mori, domesticated in China more than 5,000 years ago, belongs to the family Bombycidae, The life cycle: egg, larva, pupa and adult. Their food: mulberry leaves.
The caterpillars are celebrated for spinning silk; each cocoon is comprised of a single strand of raw silk from 1000 to 3000 feet long. It takes about 2000 to 3000 cocoons to make a pound of silk. Worldwide, silkworms produce some 70 million pounds of raw silk, requiring nearly 10 billion cocoons.
The adults cannot fly, and neither eat nor drink. They mate, lay eggs, and the cycle continues.
Seker donated cocoons for the Bohart Museum's family craft activity and watched visitors gleefully turn the cocoons into decorated finger puppets.
Among the visitors: 40 students from the Samuel Jackson Middle School and the James Rutter Middle School, Elk Grove Unified School District, in a program offering special educational opportunities and mentoring. The youths wore t-shirts lettered with "The Power of Us" on the front, and "Resilient, Authentic, Passionate" on the back. Academic mentor Keishawn Turner said the group toured the campus, had lunch, and ended the day by attending a UC Davis football game.

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 Bohart Museum of Entomology at the University of California, Davis, is sponsoring its annual "Parasitoid Palooza" open house on Saturday, Oct. 19 from 1 to 4 p.m. in Room 1124 of the Academic Surge Building on Crocker Lane.
"An insect parasitoid is a species whose immatures live off of an insect host, often eating it from the inside out," said Tabatha Yang, education and outreach coordinator of the Bohart Museum. "It is part of their life cycle and the host generally dies."
The event, free and family friendly, will include a display by senior museum scientist Steve Heydon, who studies Pteromalids, or jewel wasps, a group of tiny parasitoids. He will be available for questions about his research or parasitoids.
There are some 3,450 described species of Pteromalids, found throughout the world and in virtually all habitats. Many are important as biological control agents.
Also planned at the open house:
- A family craft activity, to be announced
- Sampling of Chirp Chips, from the Bohart Museum's recent entomophagy open house
- Display of orange and black Harlequin beetles (just in time for Halloween) from the Ian Grettenberger lab, UC Davis Department of Entomology and Nematology
- Display of cucumber beetles, which can be a pest on squashes, cucumbers and other members of the cucurbits family
The Bohart Museum, directed by Lynn Kimsey, professor of entomology at UC Davis, 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.
Special attractions include a “live” petting zoo, featuring Madagascar hissing cockroaches, walking sticks, praying mantids and tarantulas. Visitors are invited to hold some of the insects and photograph them. The museum's gift shop, open year around, includes T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.

Sure you have.
Insect fragments are in just about all the foods we eat, from chocolate to coffee to wheat flour to pizza sauce to beer and more. An insect control company estimates that we eat, on the average, 140,000 "bug bits" every year. (See Business Insider.)
But now you can REALLY eat a bug. And experience the joy and adventure of eating a new and exciting kind of protein.
The Bohart Museum of Entomology is hosting an open house themed "Gobble, Gobble, Munch, Munch, Crunch: Entomophagy,” from 1 to 4 p.m., Saturday, Sept. 21 in Room 1124 of the Academic Surge Building on Crocker Lane. Open to the public, it's free and family friendly, said Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis.
“The theme is entomophagy and we have some samples from various companies coming our way,” said Tabatha Yang, education and outreach coordinator. Companies providing samples include Hotlix, Exo and Chirps Chips.
"Just think of insects as terrestrial shrimp or crab," said senior museum scientist Steve Heydon.
In preparation for the event, Bohart Museum volunteer Iris Bright, a second-year biology major at Sacramento City College, sampled crickets, mealworms and earthworms last week.
Bright liked them all. “They're good,” she said, as she tasted red, green and blue earthworms. She described them as having "a sweet and sour taste." The mealworms? “Somewhat cheesy.”
“The crickets are crunchy," she said, adding "I've had them before.”
Bright, who plans to obtain a degree in biology and a field ecology certificate and then her master's degree, joined the Bohart Museum of Entomology/Folsom Lake College team that recently collected insects in Belize. She's studied with Belize bioblitz team leader Fran Keller, an assistant professor at Folsom Lake College who received her doctorate in entomology at UC Davis.
Eighty percent of the world population, including those living in Central and South America, Africa, Asia, Australia, and New Zealand, consume insects as a high protein source. Some 1700 species of insects are edible.
The Food and Agriculture Organization of the United Nations (FAO) has registered some 1,900 edible insect species and estimates that there were, in 2005, some two billion insect consumers worldwide. FAO suggests eating insects as a possible solution to environmental degradation caused by livestock production. Insects and arachnids eaten globally include crickets, cicadas, grasshoppers, ants, various beetle grubs (such as mealworms, the larvae of the darkling beetle, various species of caterpillars (such as bamboo worms, Mopani worms, silkworms and waxworms), scorpions and tarantulas, according to Wikipedia.
Spencer Michels in a PBS News Hour report in May 2017, commented: “But the big advantage of eating insects is that they are generally healthier than meat. A six-ounce serving of crickets has 60 percent less saturated fat and twice as much vitamin B-12 than the same amount of ground beef. ..Bugs also don't spread disease to humans the way cows — think mad cow disease– or pigs can.”
“I do realize that insects do have a bad rap,” California Academy of Sciences entomologist Brian Fisher recently said. “Most people see insects are pests or as dangerous. But it's just the opposite. Insects are less dangerous and less of a problem for humans in terms of disease."
“We do have concerns about disease jumping from animals like pigs and cows to humans,” Fisher said. “But there are no worries about a disease jumping from an insect to humans. The more evolutionary distant we are from our food source, the less danger there is. … There is almost zero chance that any disease that affects an insect could actually impact a human after it's cooked.”
Celebrity bug chef David George Gordon, author of the “Eat-a-Bug” cookbook, extolled the virtues of the “bugs as food” movement when he addressed a UC Davis audience in 2014 at the Robert Mondavi Institute for Wine and Food Science. Insects are an environmentally friendly source of protein, he said, and bug farming reduces greenhouse gas emissions and is exponentially more water-efficient than farming for beef, chicken, or pigs.

She's one of the 10 fly researchers who will greet the public and answer questions about insects in the Diptera order and talk about their research and career possibilities. The event, free and open to the public and family friendly, will be held from 1 to 4 p.m. in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis campus.
The theme is "Time's Fun When You're Studying Flies." That's a take-off of "Time flies when you're having fun."
Wishon, who holds a bachelor of science degree in entomology from UC Davis, worked at the California Department of Food and Agriculture from 2012 and 2016, and as a forensic investigator with the Sacramento Police Department from 2016 to 2017. She has also worked at the Bohart Museum and in the Phil Ward ant lab in the UC Davis Department of Entomology and Nematology.
She is now seeking her master's degree.
"I am in the process of applying to Dr. Trevor Stamper's laboratory in the Entomology Department at Purdue University," she related. "Dr. Stamper is the Forensics Science Program director and works, primarily, on the identification and biology of forensically significant dipteran. Currently, his lab is focused on testing the idea that potential evaporation, and the environmental parameter it comprises, regulate vertebrate decomposition rates across broad geographical space. If accepted, I will be studying humidity as a variable for oviposition behavior in the decomposition process. Additionally, I will use SEM (scanning electronic microscope) and molecular data to support insect identification and develop a practical pictorial key for forensically significant Diptera egg identification."
At her booth, "I will speak to this research as well as general forensic entomology and other research I have participated in, including Dr. Robert Kimsey's fire-death related entomology evidence for determining minimum PMI (post-mortem interval)." She also will display equipment.
Danielle is a past president of the UC Davis Entomology Club, and the recipient of the Department's 2011 Outstanding Undergraduate Student Award. At the plaque ceremony, Kimsey, a forensic entomologist and the club advisor, praised her as "the hardest working student I have ever seen. And, her overwhelming concern for humans of all kinds earns her the title of latter day Florence Nightingale."
Danielle has always loved insects and "anything creepy crawly. for that matter."
We remember featuring her in a 2011 blog. Tracing her love of insects to her early childhood, Danielle acknowledged that while other girls played with dolls, she spent many of her non-school hours collecting and playing with insects, snails and slugs, pill bugs, spiders and other invertebrates.
At age 4, she created a habitat for 30 garden snails in a shoebox. “I took the box up to my room and put it under my bed. Sometime later I came crying down the stairs because all of my snails had left me. Apparently I had not yet learned the concept of a lid. My mother then proceeded to help me collect my snail pets off my bed post, the walls, the nightstand…”
Although Danielle has always loved insects, she was unaware she could make a career out of it. She mentioned that in the third grade, “we had to write an autobiography and description of our desired future.” She wrote that she wanted to become an ice skater and have six children.
“It's amazing how times change,” Danielle commented. “Soon after I completed it, a family friend who knew my affinity for insects, read the autobiography and informed me that I could become an entomologist. It had never occurred to me that I could play with insects as a profession.”
Born on Coronado Island, Danielle moved to Las Vegas at age 11. “My insect collecting was limited while I lived in Las Vegas, but I kept several black widows, jumping spiders, and beetles. I also dipped into herpetology a bit and became the editor of the Southern Nevada Herpetological Society.”
Danielle attended colleges in Las Vegas and San Diego before settling in Rocklin and Davis.
While studying for her entomology degree at UC Davis, Danielle reared bed bugs for several years, sharing them with other scientists and at open houses at the Bohart Museum. She no longer keeps a colony of bed bugs but keeps or retains fond memories of UC Davis and the Department of Entomology and Nematology.
And now, her sights are set on a master's degree in entomology.
"Time's Fun When You're Studying Flies."
Danielle will be joining these fellow fly researchers at the open house:
- Fourth-year doctoral student Charlotte Herbert Alberts of the Lynn Kimsey lab, Bohart Museum, who studies assassin flies
- Graduate student Socrates Letana of the Lynn Kimsey lab, Bohart Museum, who studies botflies
- Doctoral student Caroline Wright Larsen of the James R. Carey lab, who studies non-native non-native tephritid flies, including Mediterranean fruit flies
- Graduate students Cindy Truong and Yao Cai and undergraduate students Cindy Truong and Christopher Ochoa, all of the Joanna Chiu lab, who research fruit flies
- Undergraduate student Kathlyne-Inez Soukhaseum of the Frank Zalom lab, who researches the fruit fly, the spotted-wing drosophila, Drosophila suzukii
- Nermeen Raffat, a visiting scholar in the Sharon Lawler lab, who studies "the effect of copper sulphate and other toxicants on the development and anti-predatory behavior of the mosquitoes larvae."
"Besides checking out the flies, this is also a good time for visitors to inquire about graduate school, ask about starting research projects, and to meet people working in forensics, evolution, agriculture, animal behavior, genetics, geography, and home pests, among other topics," said Tabatha Yang, education and outreach coordinator.
Entomologist Jeff Smith, who curates the Bohart's butterfly and moth section, will be on hand to open the Diptera section and answer questions. A family craft activity is also planned.
The Bohart Museum houses nearly eight million insect specimens, a live "petting zoo" (think Madagascar hissing cockroaches, stick insects and tarantulas) and a year-around gift shop. The museum 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.
