Scientists at the UC Davis Bohart Museum of Entomology will help you do just that.
They've scheduled an 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.
"We will have a number of people who are expert at raising insects, both for research and for fun," said Tabatha Yang, Bohart Museum education and outreach coordinator. 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)," Yang said. 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.

When we last left Ms. Mantis, a female Stagmomantis limbata residing in our verbena patch, she was munching on a honey bee.
A successful ambush stalker, she was.
But not always.
Her plan to take down a duskywing butterfly, genus Erynnis, didn't go so well.
The butterfly, foraging on the blossoms, touches down near the predator, unaware of the trouble that could lie ahead.
The predator and the prey. The skillful hunter and the unsuspecting prey. Ms. Mantis is poised, ready to strike. The butterfly flutters away in the nick of time.
It will live to forage another day.
The mantis? It will live to hunt another day.

Yes, I'm hungry.
A female praying mantis is perched upside down in our pollinator garden. She has maintained this position in the verbena over a four-day period, enduring temperatures that soar to 105 degrees.
The mantis, a Stagmomantis limbata (as identified by praying mantis expert Lohit Garikipati of UC Davis) remains persistent, even as the temperature gauge spikes and the insects vanish.
Then on Saturday afternoon, we notice a few honey bees and Valley carpenter bees buzzing around her, and Gulf Fritillary butterflies and skipper butterflies fluttering next to her.
The predator and the prey. The hunter and the hunted. Will she be a successful hunter today? No, not today. Maybe tomorrow.
On Sunday morning, with the temperature hovering at 80 degrees, it happens. A sluggish honey bee makes the fatal mistake of nectaring on a blossom next to her.
Bad day for the honey bee; good day for the mantis. The mantis grabs the bee with her spiked forelegs, clutching it firmly, and begins to eat.
Freeloader flies, Milichiidae (probably genus Desmometopa), arrive too late to partake in the meal.
Ms. Mantis, now nourished, scales a verbena stem.
Am I hungry? Well, I can still eat a bite.

We rarely see an adult praying mantis until late summer or fall.
Their offspring are out there, though.
And sometimes we see life go full circle.
On Sept. 23, 2018, we watched a Mama Stagmomantis limbata, as identified by UC Davis entomology student and mantis expert Lohit Garikipati, a Bohart Museum of Entomology associate who rears mantids) grace our planter with an ootheca in Vacaville, Calif.
As we mentioned in a previous Bug Squad blog:
"She climbed a redwood stake, looked around, saw me (oh, no problem, you're not a predator!), and crawled over to the other side. She positioned herself upside down, bulging abdomen intact, and proceeded to do her business. A frothy cream-colored substance began to emerge. (See my short YouTube video.) When darkness fell, she was still there."
"When Monday dawned, she was still there, her ootheca finished and hardening. It probably contains several hundred eggs, but who's counting? However, scientists estimate that only one fifth will survive to adulthood. Many of the nymphs will be eaten by their hungry brothers and sisters. Bon appétit!"
Fast forward to May 13, 2019. We spotted an offspring cradled in a leaf a few inches from the ootheca. "First-instar, Stagmomantis limbata," Garikipati said. "Must be an ooth nearby."
And then on May 19 our "star"--or maybe one of its siblings--came up missing a chunk of its abdomen. Sibling cannibalism?
No "sisterly or brotherly love," to be sure.

Henrietta, our Stagmomantis limbata praying mantis, perches on a Mexican sunflower (Tithonia).
She is as patient as she is persistent.
The drone fly, aka syrphid and also known as a hover fly or flower fly, makes the fatal mistake of touching down on the same blossom.
Henrietta eyes it hungrily. Faster than a blink of the eye, she snares it, clutching it between her spiked forelegs.
"Well, of course, I like drone flies," she appears to be saying, between mouthfuls. "Thank you for asking."
Praying mantids are not known for their table manners. It's grab, hold and eat.
The cycle of life in the garden.
