Mark your calendars for a "parade of parasitoids!"

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.

The Bohart Museum holds special open houses throughout the academic year. Its 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.

If you want to know what it's like to eat a bug—doesn't everybody?--ask an entomologist, a bug ambassador, or an entomophagist, one who eats insects.

So we did…Because the Bohart Museum of Entomology is hosting an open house on entomophagy from 1 to 4 p.m., Saturday, Sept. 21 in Room 1124 of the Academic Surge Building on Crocker Lane--and you're invited.

The event, free and family friendly, is an opportunity to participate in the joy of eating...drum roll...insects! And for that, you'll get a button proclaiming “I ate a bug at the Bohart."

If you're not into eating insects, you can cuddle and photograph the critters in the live "petting zoo," or view insect specimens. Just remember that 80 percent of the world consumes insects as a protein source. Some 1700 species of insects are edible.

“Many insects are quite edible and if you try them, you might find that crickets are the new shrimp,” says Lynn Kimsey, director of the Bohart Museum and professor of entomology, UC Davis Department of Entomology and Nematology. “Personally, I like flavored mealworms."

"Just think of insects as terrestrial shrimp or crab," adds senior museum scientist Steve Heydon.

Now, what do other entomologists and bug ambassadors think about eating insects?

Danielle Wishon
Danielle Wishon, who holds a bachelor's degree in entomology from UC Davis, is an entomophagist. She likes baking with mealworms when she's not working five jobs, including (1) teaching assistant in the lab of UC Davis alumnus Fran Keller, assistant professor at Folsom Lake College, and (2) police services officer for the Lafayette Police Department.

“Mealworm cookies are visually fun and taste good,” Wishon said. “It's my understanding that people with nut allergies will sometimes make cookies and cakes with ground-up mealworms because they have a ‘nutty flavor' but don't bother their allergies. Crickets are good as well, but only if they are baked or sauteed.”

Rather than asking "why,” Wishon asks "why not?"

“Most of the world includes arthropods in their diet,” Wishon noted. “We do, too; we just think of them differently because we pull them out of the sea. Depending on the arthropod, they are healthy, abundant, and an eco-friendly alternative to other sources of protein.”

Back in 2014, Wishon participated in a “Beer and Bugs” event (Bugs and Beer—Why Crickets and Kölsch Might Be Matches in Heaven” at the Robert Mondavi Institute for Wine and Food Science. It featured UC Davis Professor Charles Bamforth, aka “The Pope of Foam,” and David George Gordon, aka "The Bug Chef," extolling the virtues of beer and bugs. Guests sampled eight different insect-inspired creations in what was billed as "an ultimate tasting experience."

Wishon ate a baked cricket. A very large cricket.

She liked it, too!

That's not to say she likes consuming all crickets. “I once ate a boiled cricket and it was absolutely disgusting!”

Leslie Saul-Gershenz
When we asked entomologist Leslie Saul-Gershenz, who holds a doctorate in entomology from UC Davis and is associate director of research, Wild Energy Initiative, John Muir Institute of the Environment, UC Davis campus, if she has cooked with insects and eaten them, she responded:

“Many times! I have baked chocolate chip chirpies,  made cricket dip surprise, mealworm pizza and eaten all of them.  I have eaten beetle larvae in Papua, New Guinea and Peru and grasshoppers in Mexico. Seriously, they are important sources of protein all around the world and they are eaten regularly in most cultures except ours.  We, of course, eat their close relatives the crustaceans without hesitation.”

Greg Kareofelas
Bohart Museum associate and naturalist/photographer Greg Kareofelas of Davis remembers when he and colleague Danielle Wishon participated in the “insect-eating affair” at the Mondavi Institute.  Frankly, he doesn't make a habit of eating insects. "My favorite is pizza," he says.

Kareofelas can usually be found at the Bohart Museum open houses showing visitors the Lepidoptera (butterflies and moth) section with curator and entomologist Jeff Smith.

“I think it was Dan Janzen (noted evolutionary biologist and conservationist affiliated with  the University of Pennsylvania) that used to say he ‘chewed' butterflies and moths to see how they would taste to birds--the “distasteful monarch” thing," Kareofelas related. "Reading that was the closest I have gotten to eating Leps (Lepidopderans).” 

“I will try and keep an open mind at the open house,” Kareofelas promised. “But my favorite is still pizza!”

'I Ate a Bug at the Bohart'
Various companies, including Hotlix, Exo and Chirps Chips, are providing samples for the Bohart Museum open house, says education and outreach coordinator Tabatha Yang. Visitors will learn about entomophagy, sample insect-based foods, make buttons (“I ate a bug at the Bohart”), view the collection, and handle insects from the petting zoo, which includes Madagascar hissing cockroaches, walking sticks or stick insects, tarantulas and praying mantids.

The event coincides with "Student Move-in Day," when students head back to campus for the academic year, and family and friends help them move.  Many campus visitors are expected to tour the Bohart Museum.

The Bohart Museum, founded by noted entomologist Richard M. Bohart (1913-2007), houses a global collection of nearly eight million specimens. It is home to the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. It also maintains a year-around gift shop, which is stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.

The insect museum is open to the public Mondays through Thursdays from 9 a.m. to noon and 1 to 5 p.m., except on holidays. More information on the Bohart Museum is available on the website at http://bohart.ucdavis.edu or by contacting (530) 752-0493 or bmuseum@ucdavis.edu.

Ever eaten a bug?

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.

The event will include learning about entomophagy, sampling insect-based foods, button-making (“I ate a bug at the Bohart”), viewing the collection, and handling insects from the petting zoo, which includes Madagascar hissing cockroaches, stick insects and tarantulas. Yang and Bohart associate Emma Cluff recently completed an online training for food handling, as required by UC Davis.

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.

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.

Oh, what a (Moth) Night!

It was a family night in more ways than one.

Families who attended the Bohart Museum of Entomology's annual Moth Night last Saturday, Aug. 3, not only saw  specimens from scores of insect families inside the UC Davis insect museum, but outside as well.

The blacklighting display drew at least 11 different species from five moth families: Tineidae, Tortricidae, Pyralidae, Geometridae, and Noctuidae, according to Bohart associate and "Moth Man"  John De Benedictis.

De Benedictis, along with senior museum scientist Steve Heydon and Bohart associate Greg Kareofelas, set up the blacklighting display, comprised of a hanging white sheet illuminated by a generator-powered ultraviolet (UV light).

Moths that visited the blacklighting display from around 9:15 to 11 p.m. included:

Family Tineidae:
Opogona omoscopa (Opogona crown borer)

Family Tortricidae:
Clepsis peritana
Platynota stultana (omnivorous leafroller)
Cydia latiferreana (filbertworm)

Family Pyralidae:
Achyra rantalis (garden webworm)
Ephestiodes gilvescentella (dusky raisin moth)
Cadra figuliella

Family Geometridae:
Digrammia muscariata

Family Noctuidae:
Spodoptera exigua (beet armyworm)
Spodoptera praefica (western yellow-striped armyworm)
Parabagrotis formais

In comparison, De Benedictis found 14 species in his backyard the following night, while Karofelas found nine in his yard. Both live in Davis.

"At this time of year, I get 15 to 20 species most nights," said De Benedictis, an entomologist who started blacklighting in his backyard in 1998 and at Cold Canyon in 1989. "On the best nights, I'll get about 30 species in my yard and more than 100 at Cold Canyon. In recent years (since 2012), I've run my backyard light as many as 260 nights a year and have been getting 140 to 170 species each year."

Since 1998, he has recorded more than 350 species at night from his yard (including an occasional butterfly or skipper), "but there are at least 25 more that I have not identified, so I estimate I've collected 400 plus species in my yard in 21 years when diurnal (day-flying) species are included in the count."

If you attended Moth Night and you cultivate citrus, strawberries, pomegranates or cucumbers, you may have recognized some of the moths on the blacklighting display or seen the larval pests. For example, the omnivorous leafroller is a pest of citrus. The filbertworm is a pest of pomegranate. The Opogona crown borer is commonly found in bird of paradise plants, but also attacks strawberries, according to the UC Statewide Integrated Pest Management Program (UC IPM). The Spodoptera exigua (beet armyworm) and Spodoptera praefica (western yellow-striped armyworm) are pests of cucurbits (cucumber family).

Entomologist Jeff Smith, who curates the Lepidoptera (moths and butterflies) collection at the Bohart, spent the evening, 8 to 11, describing moths, showing specimens, and answering questions. "Moths can be distinguished from butterflies by their antennae, which always taper out to a fine point at the end, while butterflies' antennae end with an enlarged club," he said. "Very few butterflies can be labeled as pests, while a great many species of moths are pests, often extremely damaging kinds such as the gypsy moth, corn earworm, tent caterpillars, and California oak moth."

Smith estimates the Bohart's global moth collection at 300,000 to 350,000 specimens of moths.  "A recent donation from a local collector likely added another 25,000 specimens of moths alone."

"A great many of the colorful moths are diurnal, including hummingbird moths that mimic bumble bees, clearwing moths that mimic wasps, and Arctiid moths that mimic toxic and distasteful butterflies such as Heliconians and Glassywings from South America," Smith said.

In size, visitors saw the biggest (Atlas) to the smallest moth.  "Our smallest moth is one from Africa that was overlooked in the alcohol in which it was captured because of its tiny size," Smith pointed out. "Finally, a student separating the insects in the alcohol found it, and it is nearly microscopic."  Visitors also marveled at the hummingbird moth which has a proboscis (tongue) that 12 inches long.

Bohart associate Emma Cluff curated the silkworm moths and silks display. She gathered silkworm moths from the Bohart Museum collection, and textiles from a donation by Richard Peigler, a moth expert and biology professor at the University of the Incarnate Word, San Antonio, Texas.

The family craft activity involved coloring and stringing white cocoons (donated by Peigler) to make necklaces or bracelets. Cluff and fellow entomologist enthusiast Keely Davies created a huge luna moth in the hallway. Some 200 visitors participated in the free and family friendly event.

The moth exhibit is currently on display at the Bohart Museum.

Founded in 1946 by Richard M. Bohart (1913-2007), and directed by Lynn Kimsey, UC Davis professor of entomology, the Bohart Museum houses a global collection of nearly eight million insect speicments. It is s also the home of the seventh largest insect collection in North America; the California Insect Survey, a storehouse of the insect biodiversity; a live "petting zoo" and a gift shop.

The Bohart Museum's regular hours have changed for the summer season. As of July 3, the insect museum is hosting 30-minute tours starting at 2:30 and 3:30 pm. No reservations are required and all ages are welcome. Admission is free, but donations are always welcomed. The Bohart is open to walk-in visitors Monday through Thursday from 1 to 5 p.m. It is closed from 9 a.m. to noon to walk-in visits (the insect museum conducts many tours and outreach programs during those times). More information on the Bohart Museum is available on the website or by contacting (530) 752-0493 or email bmuseum@ucdavis.edu.
