The Bohart Museum of Entomology is hosting an open house, themed "Praying Mantises," on Sunday, Aug. 27 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. It is free and family friendly.
When asked what's fascinating about praying mantises, Lohit Garikipati, UC Davis entomology graduate (bachelor of science degree, 2019) wrapping up his master's degree with biologist Christopher Oufiero at Towson University,Towson, MD, said:
"What's fascinating about them... hard to pick just one thing! If I had to choose it would be their general awareness about the environment they are in. They are always watching, always waiting, and adjust their posture, behavior, and movement based on various environmental stimuli. They engage in some of the most interesting predatory behaviors; pouncing, lunging, spearing (yes, spearing!) and sometimes throwing themselves off of perches to secure potential prey. Few flightless predators can catch prey out of the air on the wing but many specialized species are more than capable of doing so. They are the insect equivalent of cats in many ways, but with some weird adaptations!"
Garikipati, who participated in many Bohart Museum open houses while a student at UC Davis, won't be at the open house on Aug. 27 but he will be their spirit. He plans to obtain his doctorate in entomology.
According to Kris Anderson of Las Vegas, an alumnus of Cornell University (master's degree in entomology) and author of Praying Mantises of the United States and Canada: "There are just 28 species of Mantodea found within the United States and Canada, the 7 largest of which are invasive species from other parts of the globe."
Some myths about praying mantises, as related by Anderson in his book, available on Amazon:
Myth: "Mantises sway back and forth while crawling to imitate vegetation blowing in the wind."
Truth: "The peering movement of mantises, demonstrated by the swaying back and forth of their body while ambulating or preparing to leap/take flight, is a behavioral adaptation to gain depth perception of their surroundings and has nothing to do with mimicry. Mantises blend into their environment by remaining motionless against a substrate that they morphologically resemble—not by moving. Peering movements causes the retinal images of nearby objects to be displaced more quickly than those of more distant objects, thus allowing the mantis to gain depth perception of its environment as it navigates forward."
Myth: "Mantises grab insects and immediately bite the neck/head to quickly kill their prey."
Truth: "The spinose forelegs of praying mantises are used to hold onto and prevent their prey from escaping. Once secured in their grip, the mantis will pull the prey forward and begin to meticulously chew upon whatever body part of the prey item is closest to their mouth—be it a leg, a wing, the thorax, abdomen, or head. No specific body region is exclusively targeted and the prey is always eaten alive, bit by bit, dying a slow death."
Myth: "Female mantises cannibalize the males while mating."
Truth: "With over 2,400 species of Mantodea worldwide, only a small fraction of species regularly engage in sexual cannibalism. Most do not. Of those that engage in this practice, the occurrence is not inevitable, as males typically escape and may mate with other partners."
The Bohart Museum, founded in 1946 and directed by UC Davis distinguished professor Lynn Kimsey, houses a global collection of eight million insect specimens, plus a live insect petting zoo (Madagascar hissing cockroaches, stick insects and tarantulas), and an insect-themed gift shop, stocked with t-shirts, hoodies, books, posters, jewelry and more.
The Bohart Museum is planning two other open houses this fall:
Saturday, Sept. 23: Household Vampires
Saturday, Nov. 4: Monarchs
All open houses are free and family friendly. At each event, the focus is on a special theme, but there's also a family arts-and-crafts activity, announced Tabatha Yang, education and outreach coordinator.

The “makings,” is now published. It's the first of what is expected to be many in his entomological career.
“A Checklist of Mantodea of Belize, with a Regional Key to Species,” co-authored with UC Davis professor and arachnologist Jason Bond, is now online on ZooKeys.
“Lohit did a great job on this, and there's even an online Lucid identification key,” said Bond, the UC Davis Department of Entomology and Nematology's Evert and Marion Schlinger Endowed Chair in Insect Systematics and the newly selected associate dean of the UC Davis College of Agricultural and Environmental Sciences.
“This is a great example of undergraduate research opportunities in entomology,” said Bond. Garikipati worked in the Bond laboratory as a lab assistant before and after receiving his bachelor's degree in entomology in June 2019. He is now studying for his master's degree in biology at Towson University, Md., with advisor Christopher Oufiero.
For the ZooKeys publication, Garikipati and Bond updated the list of known Mantodea in Belize, adding 12 new species to the country records, bringing the total known species of Mantodea in Belize to 21. They provided information on habitat and microhabitat observations; and a regional dichotomous key and Lucid interactive key to known species in Belize. They also included a list of other possibly endemic species. In addition, the scientists remarked on the merit of further sampling efforts in central America, based on recent studies.
“Our findings,” they wrote in their abstract, “suggest that our understanding of Central American Mantodean diversity could be vastly improved by further documentation.”
Grateful to Jason Bond. “After a probably too lengthy amount of time, I am extremely pleased to present my first publication,” Lohit wrote on his Facebook page. “I cannot understate how grateful I am to Jason Bond for providing his time and advice to help guide me through this process, it quite literally would not have been possible without his enthusiasm and support. Thanks to the other members of the Bond lab as well for their advice and critique of various parts of the manuscript during its development. Hopefully we can continue to update and document the fauna of the southern Yucatan peninsula and further our understanding of mantis distribution.”
Mantids have long fascinated Lohit, who grew up in Pleasanton, Alameda County. “I first became interested in praying mantises when I was about six years old,” he said. “I found a praying mantis on my aunt's curtain in India and had no clue what the insect was! After a lot of Googling and finding out that people kept various species as pets, I started rearing both native and exotic species.”
“Admittedly, mantises are not the easiest organism to rear; it took me a few years before I bred my first species, Mantis religiosa (Linnaeus),” Lohit said. “I was really fascinated just by their hunting methods and cryptic strategies; I think I could watch them hunt another thousand times and still be as fascinated. Currently, I think I'm pushing 40 or 50 species that I have reared, with representatives from most families. Captive observations have been a large part of fueling my interest and raising questions about these organisms, as they've afforded me the chance to watch organisms that are often rarely found in the wild.”
High Biodiversity. The June 22-July 6 bioblitz, led by biology professors and Bohart associates Fran Keller of Folsom Lake College and Dave Wyatt of Sacramento City College and headquartered at Toucan Ridge Ecology and Education Society (T.R.E.E.S) Field Station and Research Center, spanned four locations. The area boasts "some of the highest biodiversity the country has to offer," according to its website.
“Lohit and Brian Fridie (undergraduate at the University of Florida, Gainesville) captured many more individuals and more species than I ever saw on any of our trips,” said Keller, who holds a doctorate in entomology from UC Davis, where she studied with major professor Lynn Kimsey, director of the Bohart Museum and a UC Davis distinguished professor of entomology. “Granted, I was collecting everything and leading the trip but having specialists on the trip helps us gather and document insect diversity greater than we could do with just Dave and I collecting.”
“Possibly the thing that surprised me the most was the sheer underrepresentation of taxa in the country,” Garikipati said. “I had expected to maybe find one or two new country records, but I did not expect to more than double the number of species recorded from the country! The other thing that astounded me was how numerous and diverse insect populations were as well (this was my first time collecting in the tropics). Despite the sheer scope of the environment there, mantises were not an uncommon find (though they are still as a whole much more difficult to find than many insect groups).”
“It was a real pleasure searching for mantises in Belize,” Garikipati said. “My favorite find was most likely seeing wild individuals of species I'd only be able to see in pinned collections and on iNaturalist. There is something so enchanting about seeing an animal in its natural habitat, and these observations bring up many questions. It was definitely a fun experience and I am very happy to be able to contribute to our understanding of these animals.”
More Than 50 Specimens. He and his colleagues collected more than 50 specimens from 14 genera and 19 species as part of the survey. Using the specimens they collected, they generated a dichotomous key and a Lucid interactive key.
“The aim is to provide both citizens and entomologists unfamiliar with this group with an easy method to identify collected species with high accuracy,” wrote Garikipati and Bond. “Photographs in the Lucid key are included to aid with character determination.”
In their publication, the scientists thanked Julio Rivera (an entomologist at Universidad San Ignacio de Loyola in Lima, Peru) for his assistance, patience, and providing some of his unpublished work to assist in identification. “We also thank Brendon Boudinot (UC Davis doctoral alumnus) for his boundless energy, support, and methodological feedback; Philip S. Ward (professor and ant specialist at UC Davis) for assisting in identification of Formicidae; Brian T. Fridie (undergraduate at the University of Florida, Gainesville) for his assistance in collecting mantises; and one anonymous reviewer for feedback on an earlier version of the manuscript.”
Garikipati's future plans? “I am looking to continue to incorporate ecology into my comparative morphology work,” he said. “Currently, I am investigating diversity in prey capture mechanisms in mantises, which may have implications for prey specialization.” His thesis title: “Diversity of Prey Capture Mechanisms in Praying Mantises: Implication for Prey Specialization.”
“Mantises,” he said, “have long been homogenized--until relatively recently--both in terms of their behavior and morphology by the general public, and I'm hoping by showcasing diversity both in behavior and morphology, the public's perception of these animals will change. “And this research will provide us valuable insight into the impact mantises have in the ecosystems they are in, as well as their potential use as bioindicators for conservation purposes.”
